Which action demonstrates proper air management when entering a hazardous area without an electronic monitor?

• A. Plan an exit based on known breathing rate and cylinder gauge reading.
• B. Move as fast as possible.
• C. Rely on team to watch air status.
• D. Ignore air status.

Answer: (A)

In air management without an electronic monitor, the essential practice is to know how much breathing air you have left and how fast you’re using it, so you can retreat before you run out. Planning an exit based on your known breathing rate and the cylinder’s pressure reading gives you a concrete, personal estimate of remaining air and a clear moment to turn back. This approach combines objective data (cylinder gauge) with your own rate of consumption, creating a safe, proactive exit plan rather than hoping air lasts or reacting too late. Moving as fast as possible uses air faster and increases risk, so speed alone isn’t a substitute for monitoring air. Relying on teammates to watch air status or ignoring air status removes your personal responsibility and leaves you vulnerable if the plan isn’t communicated or if air usage changes, which is common with physical exertion or unexpected delays.
