What is ANSI Z359.1?
•
•
•
•
National standard for fall arrest equipment
Originally published in 1992 and revised in 1999
Covers requirements for fall arrest equipment including harnesses,
lifelines, lanyards, energy absorbers and anchorage connectors
Standard is divided into 8 sections

ANSI Z359.1 Safety Requirements
for Personal Fall Arrest Systems,
Subsystems and Components
•
•
Standard remains the same as the current standard with several
important revisions and additions
Gate hook strength of snaphooks and carabiners has changed
– Gate face must withstand load of 3,600 pounds
(up from 220 pounds)
– Side of the gate must withstand load of 3,600 pounds
(up from 350 pounds)
– Minor axis of a snaphook or carabiner, except those
with captive eyes, must withstand 3,600 pounds
(new to standard)
– Tensile load for the snaphook or carabiner
must withstand 5,000 pounds (same as old version)
ANSI Z359.1
(Continued)
•
Front-mounted D-ring element on
harnesses can now be used for fall arrest
– Maximum free-fall distance must be limited
to two feet and maximum arrest force to 900
pounds
– The old standard only allowed the frontal
D-ring to be used for ladder climbing, fall
restraint and work positioning
ANSI Z359.1
(Continued)
•
Anchorage load has changed from “3,600 pounds when certification exists”
to “two times the maximum arrest force permitted on the system when
certification exists”
•
Additions to the Equipment Rigging and Use section include requirements
that harnesses and fall arrest systems be selected and properly sized for
the user and connectors, snaphooks and carabiners must be compatible
with the equipment they are used with
Lanyards, lifelines and anchors- no knots and kept clear of workplace and
environmental hazards
•
•
Additions to the Training section include provisions that training address
how to select, inspect and use fall protection equipment; training methods
and language; and assessments of trainers
•
Editorial revisions:
– The term “user” has been clarified with the terms “competent person,” ”qualified
person” and “authorized person”
ANSI Z359.2 Minimum Requirements
for a Comprehensive Managed
Fall Protection Program
•
Guidelines to organize and manage a fall protection program
– Identify, evaluate and eliminate (or control) fall hazards through
planning
– Ensure proper training of personnel exposed to fall hazards
– Ensure proper installation and use of fall protection and rescue systems
– Implement safe fall protection and rescue procedures
•
Program required whenever one or more persons are routinely
exposed to fall hazards
ANSI Z359.2
(Continued)
•
Duties and responsibilities are laid out for each person associated
with the comprehensive fall protection program
–
–
–
–
–
–
–
–
–
–
Employer-Commitment, provide procedures, equipment and training
Program Administrator-developing program, guidance & maintenence
Qualified Person - design/installation of equipment
Competent Person- program supervisor, hazard surveys, potential
hazards, inspections, training and ability to stop work at hazardous site
Authorized Person- user of equipment, proper inspection
Competent Rescuer- procedures and training
Authorized Rescuer- user of rescue equipment and training
Qualified Person Trainer
Competent Person Trainer
Competent Rescuer Trainer
ANSI Z359.2
(Continued)
•
Inspections
– Daily inspections of fall protection equipment and
anchorages by the authorized person, or user of the
equipment, as well as yearly inspection by a qualified
person, competent person or competent rescuer are
required
– Items to verify include:
• Presence and legibility of markings and tags
• Presence of all integral components of the
equipment
• Absence of defects and damage
ANSI Z359.2
(Continued)
•
Rescue procedures
– If emergency services are not able to answer a
request for assistance in a timely manner or if
they do not have adequate equipment, then
companies should have in-house rescue
procedures and trained personnel in place
– Program effectiveness should be evaluated at
regular intervals of no more than two years
– If an accident occurs, the incident must be
thoroughly investigated and documented
promptly
ANSI Z359.4 Safety Requirements for
Assisted-Rescue and Self-Rescue
Systems, Subsystems and Components
•
Addresses safety requirements for rescue systems
– Requirements for performance, design, marking,
qualification, instruction, training, use, maintenance
and removal from service
– Equipment includes connectors, winches/hoists, descent
control devices, rope tackle blocks, and self-retracting
lanyards with integral rescue capability
– Utilized in pre-planned self-rescue and assistedrescue applications for 1-2 persons
•
Rescuer must assess workplace conditions
prior to selecting a rescue system
– Must be based on compatibility with other fall
protection equipment as well as hazards and anchorages
that are present
Values of Expanded
Fall Protection Standard
•
Provides guidance in creating fall protection programs
– Clear lines of authority and responsibility
– Detailed job planning and expanded training
•
Broadens scope of standard, additional work tasks and equipment types
– Work positioning and travel restraint
– Rescue and rope access
•
Improves strength and performance of fall protection equipment
– Increased snaphook & carabiner gate strength
– Additional testing for twin leg lanyards
– Establishes requirements for positioning, restraint and rescue equipment
•
May increase compliance and reduce number of accidents
– Protects worker from potential mis-use reducing risk and liability
– Hook changes reduce the chance of forced “roll-out” for added safety

by a competent person to do the inspection.
OSHA Definitions
Competent Person

existing and predictable hazards in the
surroundings or working conditions which are unsanitary,
hazardous, or dangerous to employees, and who has authorization
to take prompt corrective measures to eliminate them.
Qualified Person

professional standing, or who by extensive knowledge, training and
experience, has successfully demonstrated his ability to solve or
resolve problems relating to the subject matter, the work, or the
project.
Authorized Person

protection and rescue topics
• Customized capabilities/in-house and on-Site
Fall Arrest Rescue Procedures,
Innovations in Anchor Points and
Confined Space Retrieval
Fall-Arrest Rescue Regulations
OSHA 1926.502 (d) (20):
The employer shall provide for prompt
rescue of employees in the event of a fall or
shall assure that employees are able to
rescue themselves.
Rescue Plan Considerations
1. Timely Rescue
2. Review your options for Self Rescue
3. Assisted Self Rescue. Ie. Ladders, work
platforms, aerial lifts, forklift baskets
4. Remote Rescue
5. Rescue Pick-off
6. Incorporating the FD as part of your Plan.
Suspension Trauma
How long Do you have before
trauma begins?
• OSHA Says “Research indicates that
suspension in a fall arrest device can result in
unconsciousness, followed by death, in less than
30 minutes”
• If your in vertical position and your legs are
perfectly still, then you can start feeling the first
signs of shock in as little as three minutes. The
average is between five and twenty minutes.
Clearance Calculations
Situation:
• I am 6 ft tall
• Using a 6 ft shock absorbing lanyard
What’s the minimum fall
clearance (in feet) do I need
from the anchor point to nearest
Hazard for me to be safe?
Clearance Calculations
Free Fall 6’

What if I don’t have 18ft?
What if I have 16 ft of clearance?

Safety Factor
• Raise the anchor point 2’
• Use a 2’ shorter lanyard
• Use a SRL
SRL Example
• 3.5 ft for Deceleration
• 1.0 ft for D-ring slide
• 2.0 ft for Safety Factor
6.5 ft clearance required

Obstructions ?
4. Assisted Self Rescue. Ie.
Ladders, Work Platforms
• Can someone bring you a step ladder or a
rolling platform so you can stand up or
rescue yourself?
• Aerial lift, forklift baskets, JLGs
• Keep the plan simple if possible
5. Remote Rescue
• The use of specialty devices that
allow for remotely hooking up to a
fallen worker
• A conscious worker may be able to
assist in providing a safe connection
for rescue
Remote Rescue
RPD

Cantilevered Systems
Transportation: Pylon Access Stand
The customer was an airline looking to improve the way they access sensors in
the pylon area above the engines. Their existing stands were heavy and difficult to
move, and did not provide adequate fall protection. The stands are aluminum to
reduce weight, and use a curved platform to cantilever over the engine and allow a
worker to lean comfortably over the pylon, with fall protection on both sides.
