When should personnel consider exit time during an operation?

Personnel should consider exit time during an operation when the SCBA (Self-Contained Breathing Apparatus) air supply is at 50%. This is crucial because the remaining air supply indicates how much time is left for safe operations before the need for evacuation arises. Monitoring air supply ensures that firefighters maintain a sufficient reserve for returning to safety without the risk of running out of air in a hazardous environment. Managing exit times with respect to air supply is a critical safety measure that supports the overall risk management during firefighting operations.

In scenarios involving smoke or when reaching an objective, the focus is typically on the immediate tasks at hand, which can sometimes distract from exit considerations. Recognizing and acting upon the air supply levels promotes awareness and preparedness, ultimately enhancing crew safety and operational effectiveness.
