Self-Retracting Lanyard/Lifeline
Self-retracting lanyards and lifelines offer more freedom to move than shock-absorbing lanyards. Each has a drum-wound line that unwinds and retracts as the worker moves.
Self-Retracting Lifeline
If the worker falls, the drum immediately locks, which reduces free-fall distance to about 2 feet - if the anchorage point is directly above the worker. Some self-retracting lanyards will reduce free-fall distance to less than one foot.
Self-retracting lanyards are available in lengths up to 20 feet. Self-retracting lifelines, which offer more freedom, are available in lengths up to 250 feet.
- Self-retracting lanyards and lifelines that limit free-fall distance to 2 feet or less must be able to hold at least 3,000 pounds with the lanyard (or lifeline) fully extended.
- Self-retracting lanyards that don't limit free-fall distance to 2 feet must be able to hold at least 5,000 pounds with the lanyard (or lifeline) fully extended.
Rope Grab
A rope grab allows a worker to move up a vertical lifeline but automatically engages and locks on the lifeline if the worker falls.
Rope Grab System
When using a rope grab, keep the following in mind:
- The rope grab must be compatible with the lifeline.
- The rope grab must be correctly attached to the lifeline (not upside down).
- Keep the lanyard (between the rope grab and the body harness) as short as possible.
- Keep the rope grab as high as possible on the lifeline.
Shock Trauma Strap
A Shock Trauma Strap is a device integrated into or attached to a full-body harness that helps alleviate pressure on the legs and prevent suspension trauma after a fall. The strap allows the suspended worker to stand in a supported position, improving circulation until rescue occurs. It is a critical component of fall protection equipment for prolonged suspension scenarios. (See the video at the end of the module.)
