When should you begin air management planning before entering a hazardous area?

• A. Before entry and throughout the operation; continually monitor pressure and breathing rate and plan exit before reaching threshold.
• B. After entry, plan only if the air becomes critical.
• C. Only before entry, with no ongoing monitoring.
• D. After you have exited the area.

Answer: (B)

Begin air management planning before you enter and keep it active the whole time you’re in a hazardous area. You should monitor your SCBA air pressure and how hard you’re breathing continually, adjusting your actions and timing to ensure you can exit safely before your air gets too low. This proactive approach gives you a built-in margin: you’re not waiting for a crisis to plan your retreat, you’re planning with awareness of current air use and task demands. If you wait until after entry, or only plan at one moment, you lose time to react to changing conditions like increased work tempo, heat, or difficult navigation, which can cause air use to spike. Planning only before entry and then not monitoring during the mission leaves you vulnerable if consumption ramps up. Exiting after you’ve already left the area is obviously too late to prevent running out of air inside. So, the safe practice is to start planning before entry and continue monitoring throughout, with the exit planned before you reach the low-air threshold.
