A) A planned maneuver for emergency retrieval.
B) Inadvertent separation of a worker from the system.
C) Routine engagement of safety mechanisms.
D) Controlled descent during a rescue operation.

Answer 1

Unintentional disengagement (roll-out) refers to the inadvertent separation of a worker from the system.

Step-by-step explanation:

Unintentional disengagement, which is also known as a roll-out, refers to B) Inadvertent separation of a worker from the system. This term is typically used in the context of occupational health and safety, especially when discussing safety harnesses and other fall protection systems. Unintentional disengagement occurs when a worker accidentally becomes detached from a safety mechanism, leading to a potential fall or injury. It is not planned, unlike emergency retrieval maneuvers, nor is it related to the routine engagement of safety features or a controlled descent during rescue operations. For example, if a construction worker's harness were to unexpectedly unclip from the lifeline, that would constitute as unintentional disengagement, putting the worker at risk of falling.
