work at height | In any place, including ground level, where a person could fall through an opening (like an uncovered pit). On a ladder or scaffold. On a flat or sloping roof. Anywhere above the ground level. The primary focus of all "work at height" regulations and procedures is fall prevention and fall arrest (stopping a fall once it has started).
