Question 1

What is a key difference between using a Self-Retracting Lifeline in rescue/retrieval mode (SRL-R) versus a standard SRL?

Accepted Answer

An SRL-R includes a mode allowing an attendant to manually raise or lower a suspended worker, in addition to standard fall-arrest function This dual function makes the SRL-R a practical assisted-rescue tool: the same device used for fall protection during the task can be switched to rescue mode to recover a suspended casualty without needing a separate haul system rigged from scratch.

Question 2

What are the three broad categories a height-work rescue plan should cover, in increasing order of how much external help is needed?

Accepted Answer

Self-rescue, assisted (mechanically aided) rescue, and fully assisted rescue Self-rescue relies on the worker's own capability (e.g. a descent device); assisted/mechanically aided rescue uses a rope/haul system operated by colleagues; fully assisted rescue is needed when the casualty cannot participate at all.

Question 3

Why is using fall-arrest equipment WITHOUT a corresponding rescue capability considered unacceptable, even if the equipment itself functions correctly?

Accepted Answer

Because surviving the initial fall means nothing if the worker then dies of suspension trauma while waiting for help that was never planned A harness that arrests a fall but has no rescue plan behind it converts an immediate fall risk into a slower, equally fatal suspension trauma risk. Rescue planning is what makes fall-arrest equipment a complete safety system.
