When working from an aerial lift (boom-type elevating work platform), workers must:
解析
In a boom-type elevating work platform the lanyard goes to the boom or the basket, and the anchorage is part of the answer rather than an afterthought. That is what (a) gets wrong: tying off to an adjacent structure means that if the basket is struck or drifts, the worker is pulled out of it, and a displaced boom turns the lanyard into the thing that removes them. Option (b) treats the guardrails as enough; a basket that is struck, or whose boom fails, throws the occupant over the rail - the catapult effect these machines are known for. Option (c) picks a body belt and a mid-rail, and the mid-rail is the fatal half: it is a guardrail component, not an anchorage, and is not designed or rated to take arresting forces.
