If unsure about using a pre-rigged rescue setup, what should you do?

Stopping the task and asking the supervisor to show you the system is the most appropriate course of action when unsure about using a pre-rigged rescue setup. Safety is paramount in rope access work, and if there is any uncertainty regarding equipment or procedures, it is crucial to seek guidance from a supervisor or someone experienced who can provide the necessary instruction. This approach ensures clarity and understanding of the rescue system before attempting to use it, thereby minimizing risks and enhancing safety for the technician and the team.

While continuing with the task without clarification could lead to dangerous situations and is not advisable, trying to figure it out independently might also lead to errors or safety oversights. Relying on a nearby colleague could be helpful, but it does not guarantee the same level of expertise and knowledge that a supervisor would have regarding the specific setup in question. Therefore, prioritizing direct mentorship and confirmation from a supervisor is the best practice in this scenario.
