- have sufficient strength to hold the worker(s) in addition to the heaviest tools and equipment expected plus a safety factor consistent with design practice for the structural materials
- be constructed of open metal grating
- have floor surfaces treated with nonskid material for interior platforms or where open metal grating is impractical outdoors 0700, 6146, HFDS
