areas outside the platform. Exit/Enter the platform through
the gate area only. The system is designed for use by one per-
son.
Personnel must use fall protection at all times. A full body har-
ness is required with lanyard not to exceed 6 ft. (1.8 M) in
length, that limits the maximum arrest force to 900 lbs. (408
kg).

one (1) person maximum.
