• Inspection procedures.
• Fall clearances and potential swing falls.
• Proper structure/substrate anchoring to withstand the minimum required
loads.
• A rescue plan in case end user or someone is subject to a fall.
Total Fall Clearance for PFAS: According to OSHA, the total fall clearance
distance is the minimum vertical distance between the worker and the lower
level that is necessary to ensure the worker does not contact a lower level
during a fall. The total fall clearance distance is calculated before a decision
is made to use a PFAS. If the available distance is not greater than the total fall
clearance distance, it is inappropriate to use the PFAS and a fall restraint system
might be used instead. Total fall clearance distance calculations are simple to
perform based on several factors, including but not all inclusive:
• Lanyard/Self Retracting Lifeline length which may vary depending on the
device being used and their specifications. See connecting device user
manual for more information.
• The height at which the lanyard is anchored relative to where the other end
attaches to the worker’s harness.
• The distance the worker will travel as the deceleration device absorbs the
energy from the fall (i.e., slows it down.)
• The worker’s height.
• D-ring shift and a safety factor.
Below are illustrations to help guide the user to determine minimum fall
clearances and swing hazards:
