The product (raw meat or raw fish) with a weight < 15 kg which is to be processed is either fed by hand or by an
infeed device (e.g. infeed conveyor belt) and a hold down device carried to the tooth or transport roller. Using open
derinding-, skinning- and membrane removal machines, the product is pressed by hand against the blade device
and the rind, the skin or the membrane is cut off by the blade.
1.4
Not intended use
A not intended use is e.g.:
the wrong installation of a derinding-, skinning- and membrane removal machine;
the processing of flat products on open derinding machines;
working on open derinding-, skinning- and membrane removal machines without using the gloves which the
manufacturer recommends;

(normative)
Common hazards for food processing machines and reduction
reqUlirements applicable to derinding-, skinning- and membrane removal
machines
C.1 Cutting hazards
Blade handling: Blades shall be removed periodically. Cutting tools are sharp and special measures shall be taken.
For such blades, designers shall provide means of attaching a tool to the blade to avoid hand contact: and a box,
or surround guard, to protect against the sharp edges of the blade during handling and transportation. Explanations
on the use of these protective means shall be included in the Instructions for use.
Verification: Visual inspection of the machine and its documentation.
C.2 Risks 'from cleaning
In the food industry the risk from cleaning is increased due to the need for operators to clean the danger zones so
frequently including removal of blockages, assisting product flow and cleaning between different products during a
working day and gaining access to the machine parts for a thorough clean to meet the hygiene needs as required
throughout or at the end of a working day.
Hazards commonly arise from the cleaning processes or substances used to obtain the hygiene condition needed.
Where hazardous chemicals are used, e.g. concentrated caustic solutions, the derinding-, skinning-, membraneremoval machines shall be designed so that the substance is handled, diluted, used and recovered in an enclosed
system (e.g. Cleaning in place) which removes the operator from contact. Where contact is unavoidable, the
instructions to the user shall include appropriate information on the need to select and use suitable personal
protective equipment and any other protective recommendations.
Verification: By visual inspection and examination of documentation
C.3 External influences on electrical equipment
Many food machines are exposed to humid environments and wet cleaning methods which increase the risk from
electrical shock.
The designer shall employ safeguarding strategies such as:
Ensuring the possibility of impact on electrical equipment from direct (or indirect) water jets is minimised
Verification: By functional test, or examination of documentation.
45
UNI EN 12355:2010
EN 12355:2003+A1 :2010 (E)
C.4 Restoration of energy supply after an interruption
The hazards from mechanical parts unexpectedly restarting exist at all food machines where access is made into
the danger zone
EN 60204-1 :1997 provides the options of specifying or not, devices to prevent unexpected start up of machines
following a power interruption. For food machines, as the risk from mechanical hazards and the frequency of
approach to danger zones is so high, such devices shall always be used.
Verification: By visual inspection.
C.s Hazards from neglecting use of PPE
Certain personal protective equipment is required at food machines to deal with residual risks e.g.:
wearing gloves to clean and remove blades;
aprons for cleaning;
gloves to handle frozen products.
The instructions to the user shall include appropriate information on the need to select and use suitable personal
protective equipment.
Verification: Examination of the documentation
