What action should be prioritized if you hear a low air alarm while operating in an IDLH?

When a low air alarm is activated while operating in an Immediately Dangerous to Life or Health (IDLH) environment, the most critical action to prioritize is to exit the IDLH immediately. The low air alarm indicates that the air supply is depleting, which can lead to suffocation or loss of consciousness if not addressed quickly.

In an IDLH situation, time is crucial, and the risk to health and safety increases significantly as oxygen levels drop or toxic agents become more concentrated. Exiting the environment as quickly and safely as possible ensures the responder's safety and allows them to maintain their ability to operate effectively.

Remaining in the IDLH environment or continuing with current tasks would not only jeopardize your safety but could also endanger teammates who might need to assist you in an emergency. Notifying your team is important, but it should be part of the exit strategy rather than the primary focus in the face of an immediate threat signaled by the low air alarm. The most prudent response is to prioritize personal safety by exiting the hazardous area as promptly as possible.
