Consumer uses of inorganic phosphates (sodium
and potassium pyrophosphates) do not contribute
to the oral intake of phosphates. Oral intake is
predominately via food and water in the form of
food additives or similar or from natural sources. It
is therefore considered appropriate to use the
Maximum tolerable daily intake (MTDI) value of 70
mg/kg bw /day of phosphorus as calculated by the
Joint FAO/WHO Expert Committee on Food
Additives (JEFCA) as any toxicity effects noted via
the oral route are not attributable to the cation but
are as a result of high doses of phosphates.
As no acute toxicity hazard has identified, there is
no requirement to derive acute DNELs. Therefore

PNEC
Remarks
No long-term toxicity studies are available and therefore the
PNEC is based on the lowest value from the short-term
0.05 mg/L
studies (100 mg/L), the assessment factor used takes the use
of short-term data and read-across data into account. (AF =
2000)
No reliable studies are available on marine species. The
PNEC is therefore based on the short-term studies conducted
0.005 mg/L
on freshwater species. The assessment factor used takes the
use of short-term data in freshwater species and read-across
data into account. (AF = 20000)
The PNEC is based on the lowest value from the short-term
0.5 mg/L
studies (100 mg/L), the assessment factor used takes the use
of read-across data into account. (AF = 200)
The PNEC is based on the NOEC from the ASRI study. The
assessment factor used takes the use of read-across data into
50 mg/L
account and uses the assessment factor appropriate for use of
a NOEC value. (AF = 20)
No data is available for freshwater sediments. Na+, K+, Mg2+, Ca2+ and
PO43- ions are ubiquitous in the environment and are found naturally in soil,
water and sediment. All are assimilated by species residing in the sediment,
water or soil and are essential for maintaining a good chemical balance. It is
therefore unlikely that inorganic phosphates of this nature would be toxic to
sediment organisms and hence toxicity studies are scientifically unjustified.

PO43- ions are ubiquitous in the environment and are found naturally in soil,
water and sediment. All are assimilated by species residing in the sediment,
water or soil and are essential for maintaining a good chemical balance.
Furthermore inorganic phosphate fertilizers (containing Na+, K+, Mg2+, Ca2+
and PO4- ions) are often added to soils to improve soil quality. Given the
extensive use of inorganic phosphates as soil fertilizers and the natural
occurrence of the ions in the environment it is unlikely that inorganic
phosphates of this nature would have a detrimental effect on soil
macroorganisms and plants and hence toxicity studies are scientifically
unjustified.

Date of issue: xxx
Inorganic phosphates are not considered to pose a risk of secondary
poisoning as they are unlikely to bioaccumulate due to the fact that they are
not lipophillic and will therefore not accumulate in fatty tissues. It not
considered necessary to derive a PNEC to take into account the risk of
secondary poisoning and no further testing is considered necessary.
8.2 Exposure controls

12.2 Persistence and degradability
Tetrapotassium pyrophosphate is an inorganic substance, biodegradation studies are not applicable. No
further testing is deemed to be necessary.
12.3 Bioaccumulative potential
Tetrapotassium pyrophosphate hydrolyses to orthophosphate and sodium ions in aqueous and biological
systems. The degradation products of tetrapotassium pyrophosphate are essential nutrients (food elements)
for plants, and stimulate the growth of water plants (macrophytes) and/or algae (phytoplankton) and are
ubiquitous in the environment.
The potential for bioaccumulation is therefore considered to be minimal.
12.4 Mobility in soil
No data available:
A batch equilibrium study according to OECD Guideline 106 was deemed to be not applicable to
Tetrapotassium pyrophosphate for the following reasons:
Firstly, analysis of the test material may not be possible due to interference from the soil extracts that may
leach into the aqueous media during the test. This would prevent quantification of the test material.
In addition, the mobility of the test item would be dependent on the anion exchange capacity of the soils as
the main component of the test material is an anion. This absorption relationship would not be anticipated to
correlate with the organic carbon content of the soils and is considered to be beyond the scope of the OECD
106 method.

12.5 Results of PBT and vPvB assessment
According to the Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.11:
PBT Assessment, the PBT and vPvB criteria of Annex XIII to the regulation do not apply to inorganic
substances. Therefore tetrapotassium pyrophosphate is not considered to require any further assessment of
PBT properties.
12.6 Other adverse effects
No sediment or terrestrial toxicity data exists. Substance is not considered to be hazardous to
sediment dwelling or terrestrial organisms. According to the criteria of the European classification
and labelling system, the substance does not require classification as hazardous for the
environment

4. Risk Management Measures
4.1 RMMs related to workers
Organisational
measures
The employer must ensure that the required PPE is available and used according to
instructions (provide training if necessary). PPE are required when breaching the system
or handling the pure substance and concentrated solutions.
Eye wash stations should be available in case of accidental contact.
Technical
measures
Respiratory
protection
Hand
protection
Revision date: X

Transport over pipes, technical barrel filling/emptying of barrel with automatic systems
(suction pumps etc.) (Good practice)
 Use of pliers, grip arms with long handles with manual use “to avoid direct contact and
exposure by splashes (no working over one’s head)” (Good practice)
 Store in cool, dry, clean, well ventilate areas. (Good practice).
 Local exhaust / general ventilation should be present when solids are handled to
reduce the likelihood of inhalation exposure to dusts.
 Workers wear appropriate personal protective equipment, such as gloves, breathing
masks and safety glasses when breaching the system or else being in contact with the
undiluted substance.
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with a suitable efficiency (see table below) is not available. Exposure to dusts
from the handling of solid materials should be reduced by the use of local exhaust
ventilation (efficiency of at least 90%). Some processes occurring outdoors may require
respiratory protection.
If local exhaust ventilation is not available then it will be necessary to use personal
respiratory protection that is compliant with EN141 or EN 405.
Hand protection is recommended: impervious chemical resistant protective gloves.
Material: Material of gloves: Butyl rubber, BR. Fluorocarbon rubber (Viton). Nitrile rubber,
NBR. Natural rubber, NR. Chloroprene rubber, CR. Neoprene gloves.

Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. Goggles or face protection shield should be
consistent with EN 166 or equivalent.
Skin and body
protection
Wearing of suitable protective clothing and rubber boots is recommended.
Hygiene
measures
Keep away from foodstuffs, drinks and tobacco. Wash hands before breaks and at end of
work. Keep work clothes separate.
4.2 RMMs related to the environment
Organisational
measures
Emissions to the environment must meet the requirements of Council Directive 96/61/EC
and National Regulations concerning phosphate in industrial wastewater.
Abatement
measures
related with
wastewater
The efficiency of the process is maximised in such a way that minimal emission of
phosphates into the wastewater will occur. In addition, phosphate can be precipitated from
the wastewater by addition of metal ions.
Abatement
measures
waste air and
solid waste
Emissions of particles into the air of workplaces or the atmosphere can be significantly
reduced by the use of cyclones, gas scrubbers or bag filters. Solid and liquid waste has to
be incinerated or appropriately disposed of as chemical waste.
4.3 Waste related measures
Type of waste
Liquid waste, solid residues.
Disposal
technique
The release of phosphates to wastewater is highly regulated.The residue of the containers
or the used container itself should be disposed in accordance with local requirements. See

MEASE(EBRC, Eurometaux, 2010): Used to assess exposure to inorganic solutions and
handling of solid inorganics (PROC 26).
The manufacture and processing of TKPP will not notably contribute to the oral intake of
phosphates.
It is also considered that workplace exposure limits for dust are applicable to this
substance in the countries in which the substance is manufactured and used. Therefore,
the exposure estimates will also be compared against a relevant general dust limit for an
inhalable fraction of 10 mg/m3 as described by the occupational exposure limits detailed in
the Technical Rules for Hazardous Materials – TRGS 900, January 2006 (Germany).This
applies to both industrial and professional use as although the two settings are not directly
comparable, it may be prudent to assess both the DNEL and the industrial against the
same values both for consistency and for worker safety.
A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or
national limits.
A number of industrial activities associated with the manufacture and processing of TKPP
may result in inhalation exposure of workers to the substance. The risk characterisation
ratios for these activities are given in the table below. Workers handling concentrated

however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application.
Indirect
exposure via
the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of
indirect exposure of humans via the environment is performed.
Consumer
exposure
No direct consumer exposure is anticipated with the manufacture and processing of TKPP.
It is concluded that the manufacture and processing of TKPP is of no risk for the general
public.
5.2. Environmental exposure (qualitative assessment)
Environmental
release
The production of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.
Waste water
treatment
plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be
reliably achieved by the available phosphorus removal techniques. Site-specific conditions
such as flow rate of the receiving surface water body and phosphorus concentration in the
receiving surface water body should be taken into account when implementing an
appropriate wastewater treatment. Council Directive 96/61/EC concerning integrated
pollution prevention and control and national regulations concerning phosphates in
industrial wastewater have to be followed to minimise the risk of eutrophication due to
phosphate releases.
Aquatic
pelagic
compartment
No direct acute or long-term adverse effects on aqueous or terrestrial organisms are
anticipated with orthophosphates in the environment.
Sediments
No direct acute or long-term adverse effects on aqueous or sediment organisms are
anticipated with orthophosphates in the environment.
Soil and
groundwater
No direct acute or long-term adverse effects on terrestrial organisms are anticipated with
orthophosphates in the environment.
Atmospheric
compartment
The manufacture of TKPP is not considered to pose a risk to the atmospheric
compartment.
Secondary
poisoning
Bioaccumulation in organisms is not relevant for inorganic phosphates.

A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or
national limits.
A number of industrial activities associated with the the mixing of TKPP into final products
may result in inhalation exposure of workers to the substance. The risk characterisation
ratios for these activities are given in the table below. Workers handling concentrated

*Outdoor exposure of industrial workers assumed to be reduced by 30% to give
consistency with ECETOC calculations for solids.
Workers
(dermal)
No systemic toxicity effects are expected due to the inorganic nature of the substance
however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application.
Indirect
exposure via
the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of
indirect exposure of humans via the environment is performed.
Consumer
exposure
No direct consumer exposure is anticipated with the mixing of TKPP into final products. It
is concluded that the mixing of TKPP into final products is of no risk for the general public.
5.2. Environmental exposure (qualitative assessment)
Environmental
release
Revision date: X
The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.

Waste water
treatment
plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be
reliably achieved by the available phosphorus removal techniques. Site-specific conditions
such as flow rate of the receiving surface water body and phosphorus concentration in the
receiving surface water body should be taken into account when implementing an
appropriate wastewater treatment. Council Directive 96/61/EC concerning integrated
pollution prevention and control and national regulations concerning phosphates in
industrial wastewater have to be followed to minimise the risk of eutrophication due to
phosphate releases.
Aquatic
pelagic
compartment
No direct acute or long-term adverse effects on aqueous or terrestrial organisms are
anticipated with orthophosphates in the environment.
Sediments
No direct acute or long-term adverse effects on aqueous or sediment organisms are
anticipated with orthophosphates in the environment.
Soil and
groundwater
No direct acute or long-term adverse effects on terrestrial organisms are anticipated with
orthophosphates in the environment.
Atmospheric
compartment
The formulation of TKPP is not considered to pose a risk to the atmospheric compartment.
Secondary
poisoning
Bioaccumulation in organisms is not relevant for inorganic phosphates.

Respiratory
protection
Hand
protection
Eye protection
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with an efficiency of ≥90% is not available. Exposure to dusts from the
handling of solid materials should be reduced by the use of local exhaust ventilation
(efficiency of at least 90%, please see below for specific requirements).
NOTE. For certain processes an efficiency of ≥95% is assumed. Please see below
exposure summary for details.
If local exhaust ventilation is not available then it will be necessary to use personal
respiratory protection that is compliant with EN141 or EN 405 and has a sufficient
efficiency.
Hand protection is recommended: impervious chemical resistant protective gloves. Material:
Material of gloves: Butyl rubber, BR. Fluorocarbon rubber (Viton). Nitrile rubber, NBR.
Natural rubber, NR. Chloroprene rubber, CR. Neoprene gloves.
Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. Goggles or face protection shield should be
consistent with EN 166 or equivalent.
Skin and body
protection
Wearing of suitable protective clothing and rubber boots is recommended.
Hygiene
measures
Keep away from foodstuffs, drinks and tobacco. Wash hands before breaks and at end of
work. Keep work clothes separate.
4.2 RMMs related to the environment
Organisational
measures
Emissions to the environment must meet the requirements of Council Directive 96/61/EC
and National Regulations concerning phosphate in industrial wastewater.
Abatement
measures
related with
wastewater
The efficiency of the process is maximised in such a way that minimal emission of
phosphates into the wastewater will occur. In addition, phosphate can be precipitated from
the wastewater by addition of metal ions.
Abatement
measures
waste air and
solid waste
Emissions of particles into the air of workplaces or the atmosphere can be significantly
reduced by the use of cyclones, gas scrubbers or bag filters. Solid and liquid waste has to
be incinerated or appropriately disposed of as chemical waste.
4.3 Waste related measures
Type of waste
Liquid waste, solid residues, packaging materials.
Disposal
technique
The release of phosphates to wastewater is highly regulated. The residue of the containers
or the used container itself should be disposed in accordance with local requirements. See
Section 13 of the SDS for more information.

It is also considered that workplace exposure limits for dust are applicable to this substance
in the countries in which the substance is manufactured and used. Therefore, the exposure
estimates will also be compared against a relevant general dust limit for an inhalable
fraction of 10 mg/m3 as described by the occupational exposure limits detailed in the
Technical Rules for Hazardous Materials – TRGS 900, January 2006 (Germany).This
applies to both industrial and professional use as although the two settings are not directly
comparable, it may be prudent to assess both the DNEL and the industrial against the
same values both for consistency and for worker safety.
A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or
national limits.
A number of industrial activities associated with the mixing of TKPP into final products may
result in inhalation exposure of workers to the substance. The risk characterisation ratios for
these activities are given in the table below. Workers handling concentrated TKPP solutions
or pure, solid substances are obliged to wear chemical resistant safety goggles. The use of
appropriate gloves and working suits is recommended. It is concluded that conditions can
be defined under which the potential health risks from the use of TKPP in chemical
synthesis are adequately controlled.

Workers
(dermal)
No systemic toxicity effects are expected due to the inorganic nature of the substance
however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application. Workers are recommended to wear the appropriate PPE.
Indirect
exposure via
the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of
indirect exposure of humans via the environment is performed.
Consumer
exposure
No direct consumer exposure is anticipated with the use of TKPP as a raw material and
process aid in chemical synthesis. It is concluded that the use of TKPP as a raw material
and process aid in chemical synthesis is of no risk for the general public.
5.2. Environmental exposure (qualitative assessment)
Environmental
release
The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.
Waste water
treatment
plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be
reliably achieved by the available phosphorus removal techniques. Site-specific conditions
such as flow rate of the receiving surface water body and phosphorus concentration in the
receiving surface water body should be taken into account when implementing an
appropriate wastewater treatment. Council Directive 96/61/EC concerning integrated
pollution prevention and control and national regulations concerning phosphates in
industrial wastewater have to be followed to minimise the risk of eutrophication due to
phosphate releases.

The use of TKPP as a raw material and process aid in chemical synthesis is not considered
to pose a risk to the atmospheric compartment.

Respiratory
protection
Date of issue: xxx
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with an efficiency of ≥90% is not available. Exposure to dusts from the
handling of solid materials should be reduced by the use of local exhaust ventilation
(efficiency of at least 90%, please see below for specific requirements).
NOTE. For certain processes an efficiency of ≥95% is assumed. Please see below exposure
summary for details
It is assumed that professional locations may not have sufficient local exhaust ventilation,
therefore , If local exhaust ventilation is not available then it will be necessary to use
personal respiratory protection that is compliant with EN141 or EN 405 and has a sufficient
efficiency (see table below for assumed APF and/or efficiency values).
Hand
protection
Hand protection is recommended: impervious chemical resistant protective gloves. Material:
Material of gloves: Butyl rubber, BR. Fluorocarbon rubber (Viton). Nitrile rubber, NBR.
Natural rubber, NR. Chloroprene rubber, CR. Neoprene gloves.
Eye
protection
Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. Goggles or face protection shield should be
consistent with EN 166 or equivalent. Eye protection is also recommended when workers
are using metal parts treated with TKPP.
Skin and
body
protection
Wearing of suitable protective clothing and rubber boots is recommended.
Hygiene
measures
Keep away from foodstuffs, drinks and tobacco. Wash hands before breaks and at end of
work. Keep work clothes separate.
4.2 RMMs related to the environment
Organisationa
l measures
Emissions to the environment must meet the requirements of Council Directive 96/61/EC
and National Regulations concerning phosphate in industrial wastewater.
Abatement
measures
related with
wastewater
The efficiency of the process is maximised in such a way that minimal emission of
phosphates into the wastewater will occur. In addition, phosphate can be precipitated from
the wastewater by addition of metal ions.
Abatement
measures
waste air and
solid waste
Emissions of particles into the air of workplaces or the atmosphere can be significantly
reduced by the use of cyclones, gas scrubbers or bag filters. Solid and liquid waste has to
be incinerated or appropriately disposed of as chemical waste.
4.3 Waste related measures
Type of waste
Liquid waste, solid residues, packaging materials.
Disposal
technique
The release of phosphates to wastewater is highly regulated. The residue of the containers
or the used container itself should be disposed in accordance with local requirements. See
Section 13 of the SDS for more information.

It is also considered that workplace exposure limits for dust are applicable to this substance
in the countries in which the substance is manufactured and used. Therefore, the exposure
estimates will also be compared against a relevant general dust limit for an inhalable fraction
of 10 mg/m3 as described by the occupational exposure limits detailed in the Technical
Rules for Hazardous Materials – TRGS 900, January 2006 (Germany).This applies to both
industrial and professional use as although the two settings are not directly comparable, it
may be prudent to assess both the DNEL and the industrial against the same values both
for consistency and for worker safety.
A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or
national limits.
INDUSTRIAL USERS:
Various industrial activities associated with metal treatment and finishing may result in
inhalation exposure of workers to TKPP. The risk characterisation ratios for these activities
are given in the table below. Workers handling concentrated TKPP solutions or pure, solid
substances are obliged to wear chemical resistant safety goggles. The use of appropriate
gloves and working suits is recommended. It is concluded that conditions can be defined
under which the potential health risks from the use of TKPP in metal treatment and finishing
are adequately controlled.

Workers
(dermal)
No systemic toxicity effects are expected due to the inorganic nature of the substance
however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application.
Indirect
exposure via
the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of indirect
exposure of humans via the environment is performed.
Consumer
exposure
No direct consumer exposure is anticipated with the use of TKPP in metal treatment and
finishing. It is concluded that the use of TKPP in metal treatment and finishing is of no risk
for the general public.
5.2. Environmental exposure (qualitative assessment)
Environmenta
l release
The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.
Waste water
treatment
plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be reliably
achieved by the available phosphorus removal techniques. Site-specific conditions such as
flow rate of the receiving surface water body and phosphorus concentration in the receiving
surface water body should be taken into account when implementing an appropriate
wastewater treatment. Council Directive 96/61/EC concerning integrated pollution
prevention and control and national regulations concerning phosphates in industrial
wastewater have to be followed to minimise the risk of eutrophication due to phosphate
releases.
Aquatic
pelagic
compartment
No direct acute or long-term adverse effects on aqueous or terrestrial organisms are
anticipated with orthophosphates in the environment.
Sediments
No direct acute or long-term adverse effects on aqueous or sediment organisms are
anticipated with orthophosphates in the environment.
Soil and
groundwater
No direct acute or long-term adverse effects on terrestrial organisms are anticipated with
orthophosphates in the environment.
Atmospheric
compartment
The use of TKPP and products containing TKPP for the treatment of metals is not
considered to pose a risk to the atmospheric compartment.
Secondary
poisoning
Bioaccumulation in organisms is not relevant for inorganic phosphates.

4. Risk Management Measures
4.1 RMMs related to workers
Organisational
measures
The employer must ensure that the required PPE is available and used according to
instructions (provide training if necessary). PPE are required when breaching the system or
handling the pure substance and concentrated solutions.
Eye wash stations should be available in case of accidental contact.
Technical
measures
Respiratory
protection

Transport over pipes, technical barrel filling/emptying of barrel with automatic systems
(suction pumps etc.) (Good practice)
 Use of pliers, grip arms with long handles with manual use “to avoid direct contact and
exposure by splashes (no working over one’s head)” (Good practice)
 Store in cool, dry, clean, well ventilate areas. (Good practice).
 Local exhaust ventilation may be present.
 Workers wear appropriate personal protection equipment, such as gloves, working suits
and safety glasses, when handling the TKPP in solid form or as solutions.
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with an efficiency of ≥90% is not available. Exposure to dusts from the
handling of solid materials should be reduced by the use of local exhaust ventilation
(efficiency of at least 90%, please see below for specific requirements).
NOTE. For certain processes an efficiency of ≥95% is assumed. Please see below
exposure summary for details
It is assumed that professional locations may not have sufficient local exhaust ventilation,
therefore , If local exhaust ventilation is not available then it will be necessary to use
personal respiratory protection that is compliant with EN141 or EN 405 and has a sufficient
efficiency (see table below for assumed APF and/or efficiency values).
Hand
protection
Hand protection is recommended: impervious chemical resistant protective gloves. Material:
Material of gloves: Butyl rubber, BR. Fluorocarbon rubber (Viton). Nitrile rubber, NBR.
Natural rubber, NR. Chloroprene rubber, CR. Neoprene gloves.
Eye protection
Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. Goggles or face protection shield should be
consistent with EN 166 or equivalent.
Skin and body
protection
Wearing of suitable protective clothing and rubber boots is recommended.
Hygiene
measures
Keep away from foodstuffs, drinks and tobacco. Wash hands before breaks and at end of
work. Keep work clothes separate.
4.2 RMMs related to the environment
Organisational
measures
Emissions to the environment must meet the requirements of Council Directive 96/61/EC
and National Regulations concerning phosphate in industrial wastewater.
Abatement
measures
related with
wastewater
The efficiency of the process is maximised in such a way that minimal emission of
phosphates into the wastewater will occur. In addition, phosphate can be precipitated from
the wastewater by addition of metal ions.

Abatement
measures
waste air and
solid waste
Date of issue: xxx
Emissions of particles into the air of workplaces or the atmosphere can be significantly
reduced by the use of cyclones, gas scrubbers or bag filters. Solid and liquid waste has to
be incinerated or appropriately disposed of as chemical waste.
4.3 Waste related measures
Type of waste
Liquid waste, solid residues, packaging materials.
Disposal
technique
The release of phosphates to wastewater is highly regulated. The residue of the containers
or the used container itself should be disposed in accordance with local requirements. See
Section 13 of the SDS for more information.

ECETOC TRA (2010).
MEASE(EBRC, Eurometaux, 2010): Used to assess exposure to inorganic solutions and
handling of solid inorganics (PROC 26).
The use of TKPP in manufacturing and treatment of leather and textiles will not notably
contribute to the oral intake of phosphates.
It is also considered that workplace exposure limits for dust are applicable to this substance
in the countries in which the substance is manufactured and used. Therefore, the exposure
estimates will also be compared against a relevant general dust limit for an inhalable
fraction of 10 mg/m3 as described by the occupational exposure limits detailed in the
Technical Rules for Hazardous Materials – TRGS 900, January 2006 (Germany).This
applies to both industrial and professional use as although the two settings are not directly
comparable, it may be prudent to assess both the DNEL and the industrial against the same
values both for consistency and for worker safety.
A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or
national limits.
DNEL:

Various industrial activities associated with manufacturing and treatment of leather and
textiles may result in inhalation exposure of workers to TKPP. The risk characterisation
ratios for these activities are given in the table below. Workers handling concentrated TKPP
solutions or pure, solid substances are obliged to wear chemical resistant safety goggles.
The use of appropriate gloves and working suits is recommended. It is concluded that
conditions can be defined under which the potential health risks from the use of TKPP in
leather and textiles manufacture and treatment are adequately controlled.

(dermal)
No systemic toxicity effects are expected due to the inorganic nature of the substance
however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application.
Indirect
exposure via
the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of indirect
exposure of humans via the environment is performed.
Consumer
exposure
No direct consumer exposure is anticipated with leather and textile manufacture and
treatment. It is concluded that the use of TKPP in leather and textile manufacture and
treatment is of no risk for the general public.
5.2. Environmental exposure (qualitative assessment)
Environmental
release
The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.
Waste water
treatment
plants
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be

(WWTP)
reliably achieved by the available phosphorus removal techniques. Site-specific conditions
such as flow rate of the receiving surface water body and phosphorus concentration in the
receiving surface water body should be taken into account when implementing an
appropriate wastewater treatment. Council Directive 96/61/EC concerning integrated
pollution prevention and control and national regulations concerning phosphates in industrial
wastewater have to be followed to minimise the risk of eutrophication due to phosphate
releases.
Aquatic
pelagic
compartment
No direct acute or long-term adverse effects on aqueous or terrestrial organisms are
anticipated with orthophosphates in the environment.
Sediments
Soil and
groundwater
No direct acute or long-term adverse effects on aqueous or sediment organisms are
anticipated with orthophosphates in the environment.
No direct acute or long-term adverse effects on terrestrial organisms are anticipated with
orthophosphates in the environment.
Atmospheric
compartment
The use of TKPP and products containing TKPP for the manufacture and treatment of
leather and textiles is not considered to pose a risk to the atmospheric compartment.
Secondary
poisoning
Bioaccumulation in organisms is not relevant for inorganic phosphates.

The conditions of exposure can be characterised on the basis of an AISE exposure
scenario developed for the treatment of drinking water (AISE 2009a). Accordingly, the
transfer of concentrated solutions occurs once a day for 10 minutes and treatment in the
closed process occurs once a day for 8 hours.
The daily and annual amount/emission per site is not considered to be the main determinant
for environmental exposure.

Concentration
of substance
in mixture
No information about the concentration of the substance in solid form or in dilute solutions is
available. In the first-tier assessment of exposure the concentration of TKPP in solids will be
set to 100% w/w and the concentration in the working solution to > 25% w/w, respectively.
3.3 Other relevant operational conditions
Not applicable.
4. Risk Management Measures
4.1 RMMs related to workers
Organisational
measures
The employer must ensure that the required PPE is available and used according to
instructions (provide training if necessary). PPE are required when breaching the system or
handling the pure substance and concentrated solutions.
Eye wash stations should be available in case of accidental contact.
Technical
measures
Respiratory
protection

Transport over pipes, technical barrel filling/emptying of barrel with automatic systems
(suction pumps etc.) (Good practice)
 Use of pliers, grip arms with long handles with manual use “to avoid direct contact and
exposure by splashes (no working over one’s head)” (Good practice)
 Store in cool, dry, clean, well ventilate areas. (Good practice).
 Local exhaust ventilation may be present.
 Workers wear appropriate personal protection equipment, such as gloves, working suits
and safety glasses, when handling the TKPP in solid form or as solutions.
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with an efficiency of ≥90% is not available. Exposure to dusts from the
handling of solid materials should be reduced by the use of local exhaust ventilation
(efficiency of at least 90%, please see below for specific requirements). If outdoors PRE
may be required.
NOTE. For certain processes an efficiency of ≥95% is assumed. Please see below
exposure summary for details
It is assumed that professional locations may not have sufficient local exhaust ventilation,
therefore , If local exhaust ventilation is not available then it will be necessary to use
personal respiratory protection that is compliant with EN141 or EN 405 and has a sufficient
efficiency (see table below for assumed APF and/or efficiency values).
Hand
protection
Hand protection is recommended: impervious chemical resistant protective gloves. Material:
Material of gloves: Butyl rubber, BR. Fluorocarbon rubber (Viton). Nitrile rubber, NBR.
Natural rubber, NR. Chloroprene rubber, CR. Neoprene gloves.
Eye protection
Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. Goggles or face protection shield should be
consistent with EN 166 or equivalent.
Skin and body
Wearing of suitable protective clothing and rubber boots is recommended.

protection
Hygiene
measures
Keep away from foodstuffs, drinks and tobacco. Wash hands before breaks and at end of
work. Keep work clothes separate.
4.2 RMMs related to the environment
Organisational
measures
Emissions to the environment must meet the requirements of Council Directive 96/61/EC
and National Regulations concerning phosphate in industrial wastewater.
Abatement
measures
related with
wastewater
The efficiency of the process is maximised in such a way that minimal emission of
phosphates into the wastewater will occur. In addition, phosphate can be precipitated from
the wastewater by addition of metal ions.
Abatement
measures
waste air and
solid waste
Emissions of particles into the air of workplaces or the atmosphere can be significantly
reduced by the use of cyclones, gas scrubbers or bag filters. Solid and liquid waste has to
be incinerated or appropriately disposed of as chemical waste.
4.3 Waste related measures
Type of waste
Liquid waste, solid residues, packaging materials.
Disposal
technique
The release of phosphates to wastewater is highly regulated. The residue of the containers
or the used container itself should be disposed in accordance with local requirements. See
Section 13 of the SDS for more information.

ECETOC TRA (2010).
MEASE(EBRC, Eurometaux, 2010): Used to assess exposure to inorganic solutions and
handling of solid inorganics (PROC 26).
The substance should be used in the drinking water treatment in such a way that the final
concentration of phosphate in drinking should not exceed the maximum admissible
concentration of 5 mg/L given in the Council Directive 80/778/EEC relating to the quality of
water intended for human consumption.
It is also considered that workplace exposure limits for dust are applicable to this substance
in the countries in which the substance is manufactured and used. Therefore, the exposure
estimates will also be compared against a relevant general dust limit for an inhalable
fraction of 10 mg/m3 as described by the occupational exposure limits detailed in the
Technical Rules for Hazardous Materials – TRGS 900, January 2006 (Germany).This
applies to both industrial and professional use as although the two settings are not directly
comparable, it may be prudent to assess both the DNEL and the industrial against the same
values both for consistency and for worker safety.
A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or
national limits.
INDUSTRIAL USERS:
Various industrial activities associated with the treatment of industrial waters and
wastewater may result in inhalation exposure of workers to TKPP. The risk characterisation
ratios for these activities are given in the table below. Workers handling concentrated TKPP
solutions or pure, solid substances are obliged to wear chemical resistant safety goggles.
The use of appropriate gloves and working suits is recommended. It is concluded that

* Outdoor exposure of industrial workers assumed to be reduced by 30% to give
consistency with ECETOC calculations for solids
PROFESSIONAL USERS:
Various professional activities associated with the treatment of industrial waters and
wastewater may result in inhalation exposure of workers to TKPP. The risk characterisation
ratios for these activities are given in the table below. Workers handling concentrated TKPP
solutions or pure, solid substances are obliged to wear chemical resistant safety goggles.
The use of appropriate gloves and working suits is recommended. It is concluded that
conditions can be defined under which the potential health risks from the use of TKPP in the
professional treatment of industrial waters and wastewater are adequately controlled.

(dermal)
No systemic toxicity effects are expected due to the inorganic nature of the substance
however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application.
Indirect
exposure via
the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of
indirect exposure of humans via the environment is performed.
Consumer
exposure
No direct consumer exposure is anticipated with the use of TKPP in water and wastewater
treatment. The substance should be used in the drinking water treatment in such a way that
the final concentration of phosphate in drinking should not exceed the maximum admissible
concentration of 5 mg/L given in the Council Directive 80/778/EEC relating to the quality of
water intended for human consumption. It is concluded that the use of TKPP in water and
wastewater treatment is of no risk for the general public.
5.2. Environmental exposure (qualitative assessment)
Environmental
release
The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.
Waste water
treatment
plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be
reliably achieved by the available phosphorus removal techniques. Site-specific conditions
such as flow rate of the receiving surface water body and phosphorus concentration in the
receiving surface water body should be taken into account when implementing an
appropriate wastewater treatment. Council Directive 96/61/EC concerning integrated
pollution prevention and control and national regulations concerning phosphates in
industrial wastewater have to be followed to minimise the risk of eutrophication due to
phosphate releases.
Aquatic
pelagic
compartment
No direct acute or long-term adverse effects on aqueous or terrestrial organisms are
anticipated with orthophosphates in the environment.
Sediments
No direct acute or long-term adverse effects on aqueous or sediment organisms are
anticipated with orthophosphates in the environment.

3. 1 Operational conditions related with frequency and quantities of use
Duration of
exposure at
workplace:
Frequency of
exposure at
workplace:
Annual amount
used per site:
The industrial and professional use of cleaners is characterised on the basis of an AISE
exposure scenario developed in the context of REACH (AISE 2009a) for the use of such
products. Accordingly, the transfer of undiluted cleaners may occur once a day for 10
minutes and the industrial or professional use of diluted solutions may occur once a day
for 8 hours. A single worker may be exposed on 220 days per year.
The daily and annual amount/emission per site is not considered to be the main
determinant for environmental exposure.
3.2 Operational conditions related with substance/ product
Physical state
Solid / Liquid
Concentration
of substance in
mixture
No information about the concentration of the substance in cleaners or in dilute solutions
is available. In the first-tier assessment of exposure the concentration of TKPP solid
cleaning products was > 10% w/w and the concentration in the liquid products and
working solutions was set to > 25% as a worst-case.
3.3 Other relevant operational conditions
Not applicable.
4. Risk Management Measures
4.1 RMMs related to workers
Organisational
measures
The employer must ensure that the required PPE is available and used according to
instructions (provide training if necessary). PPE are required when breaching the
system or handling the pure substance and concentrated solutions.
Eye wash stations should be available in case of accidental contact.
Technical
measures


Respiratory
protection
Revision date: X
Transport over pipes, technical barrel filling/emptying of barrel with automatic
systems (suction pumps etc.) (Good practice)
Use of pliers, grip arms with long handles with manual use “to avoid direct contact
and exposure by splashes (no working over one’s head)” (Good practice)
Store in cool, dry, clean, well ventilate areas. (Good practice).
Local exhaust ventilation may be present.
Workers wear appropriate personal protection equipment, such as gloves, working
suits and safety glasses, when handling the TKPP in solid form or as solutions.
Breathing masks are used during manual high-pressure spraying of solutions onto
surfaces. Professional users may wear gloves and safety glasses during transfer of
cleaning products and cleaning activities.
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with an efficiency of ≥90% is not available. Exposure to dusts from the
handling of solid materials should be reduced by the use of local exhaust ventilation
(efficiency of at least 90%, please see below for specific requirements). If outdoors
PRE may be required.
NOTE. For certain processes an efficiency of ≥95% is assumed. Please see below
exposure summary for details
It is assumed that professional locations may not have sufficient local exhaust
ventilation, therefore , If local exhaust ventilation is not available then it will be
necessary to use personal respiratory protection that is compliant with EN141 or EN
405 and has a sufficient efficiency (see table below for assumed APF and/or efficiency

Hand protection
Hand protection is recommended: impervious chemical resistant protective gloves.
Material: Material of gloves: Butyl rubber, BR. Fluorocarbon rubber (Viton). Nitrile
rubber, NBR. Natural rubber, NR. Chloroprene rubber, CR. Neoprene gloves.
Eye protection
Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. Goggles or face protection shield should be
consistent with EN 166 or equivalent.
Skin and body
protection
Wearing of suitable protective clothing and rubber boots is recommended.
Hygiene
measures
Keep away from foodstuffs, drinks and tobacco. Wash hands before breaks and at end
of work. Keep work clothes separate.
4.2 RMMs related to the environment
Organisational
measures
Emissions to the environment must meet the requirements of Council Directive
96/61/EC and National Regulations concerning phosphate in industrial wastewater.
Abatement
measures
related with
wastewater
The efficiency of the process is maximised in such a way that minimal emission of
phosphates into the wastewater will occur. In addition, phosphate can be precipitated
from the wastewater by addition of metal ions.
Abatement
measures waste
air and solid
waste
Emissions of particles into the air of workplaces or the atmosphere can be significantly
reduced by the use of cyclones, gas scrubbers or bag filters. Solid and liquid waste has
to be incinerated or appropriately disposed of as chemical waste.
4.3 Waste related measures
Type of waste
Liquid waste, solid residues, packaging materials.
Disposal
technique
The release of phosphates to wastewater is highly regulated. The residue of the
containers or the used container itself should be disposed in accordance with local
requirements. See Section 13 of the SDS for more information.

MEASE(EBRC, Eurometaux, 2010): Used to assess exposure to inorganic solutions
and handling of solid inorganics (PROC 26).
The use of TKPP in industrial and professional washing and cleaning will not notably
contribute to the oral intake of phosphates.
Workers
(inhalation)
It is also considered that workplace exposure limits for dust are applicable to this
substance in the countries in which the substance is manufactured and used.
Therefore, the exposure estimates will also be compared against a relevant general
dust limit for an inhalable fraction of 10 mg/m3 as described by the occupational
exposure limits detailed in the Technical Rules for Hazardous Materials – TRGS 900,
January 2006 (Germany).This applies to both industrial and professional use as
although the two settings are not directly comparable, it may be prudent to assess both
the DNEL and the industrial against the same values both for consistency and for
worker safety.

A comparison of both the DNEL and a dust limit will ensure that downstream users
have enough information on the required RMMs to ensure safe use in line with regional
or national limits.
INDUSTRIAL USERS:
Various industrial activities associated with industrial cleaning and washing may result
in inhalation exposure of workers to TKPP. The risk characterisation ratios for these
activities are given in the table below. Workers handling concentrated TKPP solutions
or pure, solid substances are obliged to wear chemical resistant safety goggles. The
use of appropriate gloves and working suits is recommended. It is concluded that
conditions can be defined under which the potential health risks from the use of TKPP
in industrial cleaning and washing are adequately controlled.

(dermal)
No systemic toxicity effects are expected due to the inorganic nature of the substance
however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application.
Indirect
exposure via
the environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of
indirect exposure of humans via the environment is performed.
Consumer
exposure
No direct consumer exposure is anticipated with the industrial and professional use of
washing and cleaning products. It is concluded that the use of TKPP in industrial and
professional use of washing and cleaning products is of no risk for the general public.
5.2. Environmental exposure (qualitative assessment)
Environmental
release
The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water
quality deterioration.
Waste water
treatment plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be
reliably achieved by the available phosphorus removal techniques. Site-specific
conditions such as flow rate of the receiving surface water body and phosphorus
concentration in the receiving surface water body should be taken into account when
implementing an appropriate wastewater treatment. Council Directive 96/61/EC

concerning integrated pollution prevention and control and national regulations
concerning phosphates in industrial wastewater have to be followed to minimise the risk
of eutrophication due to phosphate releases.
Aquatic pelagic
compartment
No direct acute or long-term adverse effects on aqueous or terrestrial organisms are
anticipated with orthophosphates in the environment.
Sediments
Soil and
groundwater
No direct acute or long-term adverse effects on aqueous or sediment organisms are
anticipated with orthophosphates in the environment.
No direct acute or long-term adverse effects on terrestrial organisms are anticipated
with orthophosphates in the environment.
Atmospheric
compartment
The use of TKPP in washing and cleaning products is not considered to pose a risk to
the atmospheric compartment.
Secondary
poisoning
Bioaccumulation in organisms is not relevant for inorganic phosphates.

Drilling may be operated on 365 days a year for 24 hours a day. A single worker may be
exposed on 220 days per year. No information about frequency and duration of the various
tasks is available. In the first-tier assessment of exposure a frequency of once a day and an
exposure duration of 8 hours was considered.
The daily and annual amount/emission per site is not considered to be the main determinant
for environmental exposure.

4.1 RMMs related to workers
Organisational
measures
The employer must ensure that the required PPE is available and used according to
instructions (provide training if necessary). PPE are required when breaching the system or
handling the pure substance and concentrated solutions.
Eye wash stations should be available in case of accidental contact.


Store in cool, dry, clean, well ventilate areas. (Good practice).
Personal respiratory equipment may be available.
Workers wear appropriate personal protection equipment, such as gloves, working suits
and safety glasses, when handling the TKPP in solid form or as solutions.
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with an efficiency of ≥90% is not available. Exposure to dusts from the
handling of solid materials should be reduced by the use of local exhaust ventilation
(efficiency of at least 90%, please see below for specific requirements). If outdoors PRE
may be required.
NOTE. For certain processes an efficiency of ≥95% is assumed. Please see below
exposure summary for details
It is assumed that professional locations may not have sufficient local exhaust ventilation,
therefore , If local exhaust ventilation is not available then it will be necessary to use
personal respiratory protection that is compliant with EN141 or EN 405 and has a sufficient
efficiency (see table below for assumed APF and/or efficiency values).
Hand protection is recommended: impervious chemical resistant protective gloves. Material:
Material of gloves: Butyl rubber, BR. Fluorocarbon rubber (Viton). Nitrile rubber, NBR.
Natural rubber, NR. Chloroprene rubber, CR. Neoprene gloves.
Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. Goggles or face protection shield should be
consistent with EN 166 or equivalent.
Wearing of suitable protective clothing and rubber boots is recommended.

ECETOC TRA (2010).
MEASE(EBRC, Eurometaux, 2010): Used to assess exposure to inorganic solutions and
handling of solid inorganics (PROC 26).
The activities associated with the drilling fluid applications will not result in oral exposure of
workers to TKPP.
It is also considered that workplace exposure limits for dust are applicable to this substance
in the countries in which the substance is manufactured and used. Therefore, the exposure
estimates will also be compared against a relevant general dust limit for an inhalable
fraction of 10 mg/m3 as described by the occupational exposure limits detailed in the
Technical Rules for Hazardous Materials – TRGS 900, January 2006 (Germany).This
applies to both industrial and professional use as although the two settings are not directly
comparable, it may be prudent to assess both the DNEL and the industrial against the same
values both for consistency and for worker safety.
A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or
national limits.
Various industrial activities associated with the drilling fluid applications may result in
inhalation exposure of workers to TKPP. The risk characterisation ratios for these activities
are given in the table below. Workers handling concentrated TKPP solutions or pure, solid
substances are obliged to wear chemical resistant safety goggles. The use of appropriate
gloves and working suits is recommended. It is concluded that conditions can be defined
under which the potential health risks from the use of TKPP in drilling fluid applications are
adequately controlled.

however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application.
Indirect
exposure via
the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of
indirect exposure of humans via the environment is performed.
Consumer
exposure
No direct consumer exposure is anticipated with the use of TKPP in drilling fluid
applications. It is concluded that the use of TKPP in drilling fluid applications is of no risk for
the general public.
5.2. Environmental exposure (qualitative assessment)
Environmental
release
TKPP is listed in the OSPAR list of substances/preparations used and discharged offshore
which are considered to pose little or no risk to the environment (PLONOR). Further,
national regulations are available to regulate the waste management from offshore and
mining industry.
The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.
Waste water
treatment
plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be
reliably achieved by the available phosphorus removal techniques. Site-specific conditions
such as flow rate of the receiving surface water body and phosphorus concentration in the
receiving surface water body should be taken into account when implementing an
appropriate wastewater treatment. Council Directive 96/61/EC concerning integrated
pollution prevention and control and national regulations concerning phosphates in
industrial wastewater have to be followed to minimise the risk of eutrophication due to
phosphate releases.
Aquatic
pelagic
compartment
No direct acute or long-term adverse effects on aqueous or terrestrial organisms are
anticipated with orthophosphates in the environment.
Sediments
Soil and
groundwater
No direct acute or long-term adverse effects on aqueous or sediment organisms are
anticipated with orthophosphates in the environment.
No direct acute or long-term adverse effects on terrestrial organisms are anticipated with
orthophosphates in the environment.
Atmospheric
compartment
The use of TKPP in drilling applications is not considered to pose a risk to the atmospheric
compartment.
Secondary
poisoning
Bioaccumulation in organisms is not relevant for inorganic phosphates.

Frequency of
exposure at
workplace:
Revision date: X
No information about frequency and duration of the various tasks is available. In the firsttier assessment of exposure a frequency of once a day and an exposure duration of 8
hours was considered. A single worker may be exposed on 220 days per year. No
information about the concentration of the substance in dilute and concentrated solutions or
in solids is available.
The CEPE has developed exposure scenarios for consumer use of coatings in the context
of the REACH regulation (CEPE 2009). These scenarios indicate a maximum duration of
use ranging from 4 to 8 hours. No use frequency is given in the CEPE scenarios. The
frequency of paint use by consumers is between 1 to 3 times a year depending on the type
of paint used; the amount of paint used per application ranges from approximately 1 to 1.3
kg (RIVM 2007b). No information about the concentration of TKPP in paints for consumer
use is given. In the first-tier assessment of exposure the concentration of the substance in
paints is set to 10 %. Paints containing TKPP are used by consumers in various ways. The
ready-to-use preparations can be purchased in retail shops. Hand mixing of other
components into the paint before use may occur. The paint mixture has to be transferred
from the transport, storage or mixing vessels to smaller containers or the spray systems.
Paints are brushed onto surfaces or sprayed using medium to high pressure systems in
private indoor or outdoor settings. Spray painting is performed manually in open processes.
Painted surfaces are air-dried. Extensive manual cleaning of the equipment after use may
be necessary.

In the first-tier assessment of exposure worst-case assumptrion were made with regards to
the composition of materials containing TKPP. The concentration of TKPP in undiluted
liquid mixtures was > 25 % w/w. The concentration of solid TKPP delivered to professional
and private users was 100% w/w and the concentration in cements, plasters and other solid
products for consumer use was 10% w/w. The amounts of products and materials used per
event may vary considerably ranging from a few grams to several hundred kilograms of
material per event.
The CEPE has developed exposure scenarios for consumer use of coatings in the context
of the REACH regulation (CEPE 2009). These scenarios indicate a maximum duration of
use ranging from 4 to 8 hours. No use frequency is given in the CEPE scenarios. The
frequency of paint use by consumers is between 1 to 3 times a year depending on the type
of paint used; the amount of paint used per application ranges from approximately 1 to 1.3

4. Risk Management Measures
4.1 RMMs related to workers
Organisational
measures
The employer must ensure that the required PPE is available and used according to
instructions (provide training if necessary). PPE are required when breaching the system or
handling the pure substance and concentrated solutions.
Eye wash stations should be available in case of accidental contact.
Technical
measures



Respiratory
protection
Revision date: X
Store in cool, dry, clean, well ventilate areas. (Good practice).
Professionals wear appropriate personal protection equipment, such as goggles,
gloves and working suits, when handling solutions or materials, cements and plasters
containing TKPP
Breathing masks may be used during transfer and mixing of solid preparations to
reduce the inhalation of dusts.
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with an efficiency of ≥90% is not available. Exposure to dusts from the
handling of solid materials should be reduced by the use of local exhaust ventilation
(efficiency of at least 90%, please see below for specific requirements). If outdoors PRE
may be required.
NOTE. For certain processes an efficiency of ≥95% is assumed. Please see below

exposure summary for details
It is assumed that professional locations may not have sufficient local exhaust ventilation,
therefore , If local exhaust ventilation is not available then it will be necessary to use
personal respiratory protection that is compliant with EN141 or EN 405 and has a sufficient
efficiency (see table below for assumed APF and/or efficiency values).
Hand protection is recommended: impervious chemical resistant protective gloves.
Material: Material of gloves: Butyl rubber, BR. Fluorocarbon rubber (Viton). Nitrile rubber,
NBR. Natural rubber, NR. Chloroprene rubber, CR. Neoprene gloves.
Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. Goggles or face protection shield should be
consistent with EN 166 or equivalent.
Skin and body
protection
Wearing of suitable protective clothing and rubber boots is recommended.
Hygiene
measures
Keep away from foodstuffs, drinks and tobacco. Wash hands before breaks and at end of
work. Keep work clothes separate.
4.2 RMMs related to consumers
It is assumed that consumers will not wear PPE. However, eye protection and hand protection is
recommended.
4.3 RMMs related to the environment
Organisational
measures
Emissions to the environment must meet the requirements of Council Directive 96/61/EC
and National Regulations concerning phosphate in industrial wastewater.
Abatement
measures
related with
wastewater
Phosphate can be precipitated from the wastewater by addition of metal ions.
Abatement
measures
waste air and
solid waste
Solid and liquid waste has to be incinerated or appropriately disposed of as chemical
waste.
4.4 Waste related measures
Type of waste
Liquid waste, solid residues, packaging materials.
Disposal
technique
The release of phosphates to wastewater is highly regulated. The residue of the containers
or the used container itself should be disposed in accordance with local requirements. See

in the countries in which the substance is manufactured and used. Therefore, the exposure
estimates will also be compared against a relevant general dust limit for an inhalable
fraction of 10 mg/m3 as described by the occupational exposure limits detailed in the
Technical Rules for Hazardous Materials – TRGS 900, January 2006 (Germany).This
applies to both industrial and professional use as although the two settings are not directly
comparable, it may be prudent to assess both the DNEL and the industrial against the
same values both for consistency and for worker safety.
A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or
national limits.
Various professional activities associated with the use of products and materials containing
TKPP in construction and building work may result in inhalation exposure of workers to
TKPP. The risk characterisation ratios for these activities are given in the table below.
Workers handling concentrated TKPP solutions or pure, solid substances are obliged to
wear chemical resistant safety goggles. The use of appropriate gloves and working suits is
recommended. It is concluded that conditions can be defined under which the potential
health risks from the use of products and materials containing TKPP in construction and
building work are adequately controlled.

* Outdoor exposure of industrial workers assumed to be reduced by 30% to give
consistency with ECETOC calculations for solids
Workers
(dermal)
No systemic toxicity effects are expected due to the inorganic nature of the substance
however local effects may occur but these effects will not be dose-dependent but will
depend on the concentration of the substance present in the mixture/solution used in a
specific application.
Indirect
exposure via
the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the
substance can be effectively removed from the wastewater. Thus, no assessment of
indirect exposure of humans via the environment is performed.
Consumer
exposure
Private users of products and materials used for construction and building work and
containing TKPP and users of paints containing TKPP may be exposed to the substance
by inhalation. The risk characterisation ratios obtained for different types of paints applied
by rolling, brushing or spraying are given in the tables below. It is concluded that the
conditions of consumer use of products and materials containing TKPP for private
construction and building work are such that the potential human health risks are
adequately controlled.

5.2. Environmental exposure (qualitative assessment)
Environmental
release
The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.
Waste water
treatment
plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be
reliably achieved by the available phosphorus removal techniques. Site-specific conditions
such as flow rate of the receiving surface water body and phosphorus concentration in the
receiving surface water body should be taken into account when implementing an
appropriate wastewater treatment. Council Directive 96/61/EC concerning integrated
pollution prevention and control and national regulations concerning phosphates in
industrial wastewater have to be followed to minimise the risk of eutrophication due to
phosphate releases.
Aquatic
pelagic
compartment
No direct acute or long-term adverse effects on aqueous or terrestrial organisms are
anticipated with orthophosphates in the environment.
Sediments
Soil and
groundwater
No direct acute or long-term adverse effects on aqueous or sediment organisms are
anticipated with orthophosphates in the environment.
No direct acute or long-term adverse effects on terrestrial organisms are anticipated with
orthophosphates in the environment.
Atmospheric
compartment
The use of TKPP and products and materials containing TKPP is not considered to pose a
risk to the atmospheric compartment.
Secondary
poisoning
Bioaccumulation in organisms is not relevant for inorganic phosphates.

3. Operational conditions
3. 1 Operational conditions related with frequency and quantities of use
Duration of
exposure at
workplace:
No information about frequency and duration of the various tasks is available. In the first-tier
assessment of exposure a frequency of once a day and an exposure duration of 8 hours was
considered. A single worker may be exposed on 220 days per year.
Frequency of
exposure at
workplace:
Annual
amount used

The daily and annual amount/emission per site is not considered to be the main determinant
for environmental exposure.
3.2 Operational conditions related with substance/ product
Physical
state
Solid / Liquid
Concentratio
n of
substance in
mixture
No information about the concentration of TKPP in liquid or solid fertilisers is available and a
concentration of 100% w/w for the undiluted product and > 25% w/w for the diluted product
was considered in the first-tier exposure assessment and worst-case.
3.3 Other relevant operational conditions
Not applicable.
4. Risk Management Measures
4.1 RMMs related to workers
Organisation
al measures
The employer must ensure that the required PPE is available and used according to
instructions (provide training if necessary). PPE are required when breaching the system or
handling the pure substance and concentrated solutions.
Eye wash stations should be available in case of accidental contact.
Technical
measures




Respiratory
protection
Store in cool, dry, clean, well ventilate areas. (Good practice).
Local exhaust ventilation may be present.
Professionals wear appropriate personal protection equipment, such as goggles, gloves
and working suits, when handling solutions or materials, cements and plasters
containing TKPP
Breathing masks may be used during transfer and mixing of solid preparations to reduce
the inhalation of dusts.
Respiratory protection: Respiratory protection is required when workers are exposure to
dusts, if LEV with an efficiency of ≥90% is not available. Exposure to dusts from the handling
of solid materials should be reduced by the use of local exhaust ventilation (efficiency of at
least 90%, please see below for specific requirements). If outdoors PRE may be required.
NOTE. For certain processes an efficiency of ≥95% is assumed. Please see below exposure
summary for details
It is assumed that professional locations may not have sufficient local exhaust ventilation,
therefore , If local exhaust ventilation is not available then it will be necessary to use

Abatement
measures
related with
wastewater
Phosphates are generally retained on soil particles and except in exceptional circumstances
will not leach through soils to ground or surface water as soluble ions. Loss to surface waters
is thus usually related to surface run-off or erosion of soil particles, which carry attached
phosphates. To avoid such effects, the following recommendations (Lory, 1999) should be
followed:

Abatement
measures
waste air and
solid waste
Apply phosphorus sources below the surface.
Surface-apply phosphorus sources during periods of the year when runoff is unlikely.
Surface-apply phosphorus sources only on fields with a low potential for runoff.
Do not surface-apply phosphorus sources to frozen or snow-covered soils.
Maintain buffer strips around water resources where no phosphorus is applied.
Add alum or similar treatment to manure to reduce the availability of phosphorus.
Solid and liquid waste has to be incinerated or appropriately disposed of as chemical waste.

No oral exposure to TKPP is anticipated with the use of TKPP in fertilisers.
It is also considered that workplace exposure limits for dust are applicable to this substance
in the countries in which the substance is manufactured and used. Therefore, the exposure
estimates will also be compared against a relevant general dust limit for an inhalable fraction
of 10 mg/m3 as described by the occupational exposure limits detailed in the Technical
Rules for Hazardous Materials – TRGS 900, January 2006 (Germany).This applies to both
industrial and professional use as although the two settings are not directly comparable, it
may be prudent to assess both the DNEL and the industrial against the same values both for
consistency and for worker safety.
A comparison of both the DNEL and a dust limit will ensure that downstream users have
enough information on the required RMMs to ensure safe use in line with regional or national
limits.
Various professional activities associated with the use of fertilisers may result in inhalation
exposure of workers to TKPP. The risk characterisation ratios for these activities are given in
the table below. Workers handling concentrated TKPP solutions or pure, solid substances
are obliged to wear chemical resistant safety goggles. The use of appropriate gloves and
working suits is recommended. It is concluded that conditions can be defined under which
the potential health risks from the professional use of fertilisers containing TKPP are
adequately controlled.

No systemic toxicity effects are expected due to the inorganic nature of the substance
however local effects may occur but these effects will not be dose-dependent but will depend
on the concentration of the substance present in the mixture/solution used in a specific
application.
Indirect

the
environment
No indirect exposure of humans via the environment is expected for TKPP, as the substance
can be effectively removed from the wastewater. Thus, no assessment of indirect exposure
of humans via the environment is performed.
Consumer

Private users of fertilisers containing TKPP may be exposed to the substance by inhalation.
The risk characterisation ratios obtained for different types of fertiliser applied are given in

5.2. Environmental exposure (qualitative assessment)
Environment

The use of TKPP can potentially result in aquatic emissions and locally increase the
3phosphate (PO4 ) concentration. Phosphates reaching surface water increase the
phosphorus content in the water body which may cause eutrophication and water quality
deterioration.
Waste water
treatment
plants
(WWTP)
Phosphorus should be removed from industrial wastewater before it is released to the
environment. This can be done by chemical treatment (by precipitation with the help of
aluminium or iron addition) or biological treatments. A high degree of removal can be reliably
achieved by the available phosphorus removal techniques. Site-specific conditions such as
flow rate of the receiving surface water body and phosphorus concentration in the receiving
surface water body should be taken into account when implementing an appropriate
wastewater treatment. Council Directive 96/61/EC concerning integrated pollution prevention
and control and national regulations concerning phosphates in industrial wastewater have to
be followed to minimise the risk of eutrophication due to phosphate releases.
