Question

a personal fall - arrest system must be secured properly to a(n) ______. anchorage point warning line positioning device stanchion

Explanation:

A personal fall - arrest system is designed to stop a fall. An anchorage point is a secure point to which the fall - arrest system is attached to provide the necessary support and arrest the fall. A warning line is used for warning, not for securing the fall - arrest system. A positioning device is for holding a worker in place, not for arresting falls. A stanchion is a vertical post, not the correct point for securing a fall - arrest system.

Answer:

A. Anchorage point
