What is a principle of air management that firefighters should observe?

Always knowing how much air is left by checking the air gauge is essential for firefighter safety and effectiveness during operations. This principle of air management allows firefighters to stay aware of their air supply, helping them to make informed decisions regarding their operational time and the necessity to exit the hazardous environment. By consistently monitoring the air gauge, firefighters can avoid running low on air, which could jeopardize their safety and ability to perform their tasks effectively.

Being aware of the air supply ensures that firefighters can balance their operations, manage their time effectively, and maintain communication and coordination with their team. It is a proactive measure that enhances situational awareness, ultimately leading to safer outcomes in emergency scenarios. Other principles, while important, do not directly address the critical need for air supply awareness in life-threatening conditions.
