Personal Fall Arrest Systems. Personal fall arrest systems are designed to control the fall of a worker and minimize the injury once a worker has fallen. Personal fall arrest systems consist of the following components: • Full body harness (body wear) • Shock absorbing lanyard or retractable (connecting device) • Tie off point (anchorage) • Training Specific Requirements • Safety harness is the only acceptable means of personal fall arrest system permitted on any Webcor/Obayashi project; the use of body belts is not acceptable for fall protection (including positioning systems). • Retractable lanyards are the most preferred fall protection systems for this project. • Each subcontractor and tiered subcontractor is responsible for providing and requiring the use of safety harnesses, lifelines and lanyards when workers are exposed to a fall of 6 feet or greater. • All subcontractors must provide safety harness at their cost when fall protection is required. • All lanyards must be equipped with locking snap hooks. • Appropriate shock absorbing lanyards will be used for fall protection when they do not create a greater hazard due to the length of the potential fall. • Shock absorbing lanyards are not to be used in combination with a retractable lanyard. • Any safety harness, lifeline or lanyard actually subjected to in-service loading MUST be immediately removed from service and should not be used again for worker safeguarding. • Fall arrest equipment should be removed from service when evidence of wear is detected. • Retractable lifelines are preferred where direct anchorage is not available. • All safety harnesses, lifelines and lanyards must have a nominal breaking strength of 5,000 lbs (5,400 lbs in CA). • The anchorage (tie off point) must be capable of withstanding a minimum 5,000 lbs (5,400 lbs in CA) tensile strength per worker attached. • Anchorage used for attachment of personal fall arrest equipment should be secured above the point of operation whenever possible • Anchorage, tie off, must generally be above the worker’s head. • Anchorage must be high enough that the worker will not strike any lower level surface or object should a fall occur. • All fall protection equipment shall be inspected daily/monthly and before each use, with documentation made available upon request that it is in proper working order.
Personal Fall Arrest Systems. These consist of an anchorage, connectors, and full body harness, and includes a deceleration device, lifeline, or suitable combinations. If a personal fall arrest system is used for fall protection, it must do the following:
Personal Fall Arrest Systems. These consist of an anchorage, connectors, and a body belt or body harness and may include a deceleration device, lifeline, or suitable combinations. If a personal fall arrest system is used for fall protection, it must do the following: • Limit maximum arresting force on an employee to 900 pounds (4 kilonewtons) when used with a body belt; • Limit maximum arresting force on an employee to 1,800 pounds (8 kilonewtons) when used with a body harness; • Be rigged so that an employee can neither free fall more than 6 feet (1.8 meters) nor contact any lower level; • Bring an employee to a complete stop and limit maximum deceleration distance an employee travels to 3.5 feet (1.07 meters);and • Have sufficient strength to withstand twice the potential impact energy of an employee free falling a distance of 6 feet (1.8 meters) or the free fall distance permitted by the system, whichever is less. • The use of body belts for fall arrest is prohibited and a full body harness is required. Personal fall arrest systems must be inspected prior to each use for wear damage, and other deterioration. Defective components must be removed from service.
