- A rigid track type system gives very little, so it can provide a more robust protection.
In scenarios where the work area is limited and the worker does not to move about very much, a single point attachment can be used to allow a worker to hook-in with their restraint lanyard to a designated point in the ceiling (using a structural eye-bolt or some type of a load-rated beam clamp). In this case, the worker’s movement is limited, per OSHA, to 30° off of plumb, but they are still protected in the event of a freefall. The 30° limitation is to prevent the worker from swinging too far in a pendulum motion where they might swing back and smash into a wall or other protruding hazard.
The typical theatrical fall protection focus, however, is on systems designed for workers who will be working in a potential fall hazard area — such as workers who must adjust lighting equipment at height or climb about on fixed or portable trusses. Common locations for Fall Protection requirements in the theatre are:
- Balcony Railing Lighting Bars
- Tormentor Boom Lighting Pipes
- Scissors Lifts and Boom Arm Lifts
- Weight Loading Gallery Rails
- Open Beams and Trusses
- Fixed Vertical Ladders (with and without cages)
- Roll-up ladders (like are used to access concert trusses)
- Upper level storage areas where there can be open sections of the railing
- Follow Spotlight Platforms
- Elevated Paint Bridges
