When low air alarms activate on an SCBA, how far can a firefighter travel in good conditions until the air supply is exhausted?

When low air alarms activate on a Self-Contained Breathing Apparatus (SCBA), it is generally understood that a firefighter can safely travel up to 150 feet in good conditions before their air supply is exhausted. This distance is based on typical operational protocols which allow for the evaluation of air consumption under standard conditions.

The alarm serves as a critical warning that air levels are decreasing, prompting the firefighter to proceed with caution and ensure they are aware of their surroundings, assessing a safe route back to a designated safe area or exit. This distance also allows for some buffer time in emergencies, providing enough air for any unexpected delays during an evacuation.

It's important to consider that the actual distance can vary based on individual usage rates, environmental factors, and the specific situation at hand. However, the standard operating procedures establish 150 feet as a reliable metric under normal circumstances, reflecting training and safety protocols established for firefighters in the field.
