When are entrants allowed to be off the retrieval line during vertical entries?

Entrants are allowed to be off the retrieval line during vertical entries when it is deemed safe to do so. This implies that there are specific conditions under which the safety of the entrants can be ensured. The retrieval line serves as a vital safety measure, providing a means for workers to be rescued if they become incapacitated or if an emergency arises. However, if the situation has been assessed and determined to be safe—such as the environment being free from hazards, or when the entrant has been properly trained and equipped to work without the line—then they may be allowed to detach for specific, short durations to perform tasks or assist others.

Situations where entrants would never be allowed off the retrieval line would expose them to increased risk, as the line is a critical safety tool in confined spaces. Similarly, detaching the line when lifting a victim could hinder rescue efforts, and not having lines available does not create a safe scenario for a person to be off the retrieval line. Thus, the emphasis is on safety and risk assessment before making any decision to allow entrants to detach from the retrieval line.
