Working at Heights – Below the Permanents Multiple Rope Grab System
When work at heights below the permanents cannot be accomplished by using a ladder, aerial lift, or scaffolding, (for instance, when hanging greenbeds or walking on the top of set walls), you must use fall arrest equipment. When you need to move long distances horizontally across the set, use a multiple rope grab system. Two or more rope grab set-ups will allow you to travel across the set without risking a swing fall. This equipment includes: a full body harness with self-retracting lanyards, vertical lifelines with rope grabs, tag lines, and a double D-ring extender.
- Inspect all fall protection equipment prior to use.
- Locate an anchorage point for each of your vertical lifelines. Single-user anchorage points
- are located on the soundstage trusses and have been identified with a yellow tag.*
- Select anchorage points above you and as close as possible to where you are going to be working to avoid or limit a swing fall.
- Connect the vertical lifelines to the anchorage points you have chosen with the double- locking snap hook. Attach only one vertical lifeline per anchor point.
- Attach the manual rope grab to each vertical lifeline. Make sure that the arrow on the rope grab is pointing up toward the anchorage point.
- Attach the self-retracting lanyard (SRL) to the rope grab with a self-locking carabiner.
- Connect the tag line to the double-locking snap hook on the SRL.
- Position the rope grab, SRL and tag line on the lifeline so that the final height of the SRL is 6 feet above your intended work height.
- Protect the lifeline against rough edges by using a rope protector or by padding sharp corners.
- From the ground or greenbed, pull the tag line and attach the double-locking snap hook from the SRL to the double D-ring extender located on the back of your harness.
- Never remove one lifeline until you are safely attached to the second lifeline, or until you are back on the ground or greenbed.
