If the SCBA gauge shows near-zero pressure during a mission, what should you do?

• A. Continue the mission at a slower pace.
• B. Immediately retreat to fresh air and exit the hazard area with your team.
• C. Remove the facepiece to get more air.
• D. Notify supervisor after completing the task.

Answer: (B)

Running out of air means your priority is to get to breathable air and remove yourself from the hazardous area with your team. When the gauge shows near-zero, you should stop and immediately retreat to fresh air, exiting the hazard area together with your crew. This quick action protects you from running out of air while still in the danger zone and helps keep teammates safe by maintaining a controlled, coordinated withdrawal. Continuing at a slower pace, removing the facepiece, or delaying action to notify someone after finishing the task all increase the risk of air exhaustion or exposure without protection. The safest response is to retreat right away to a safe environment where you can re-establish your air supply and reassess the situation.
