What should a firefighter do if they notice their SCBA's air gauge reads low?

When a firefighter notices that their SCBA's air gauge reads low, the appropriate response is to immediately exit the hazardous area. This course of action is crucial for ensuring the firefighter's safety. SCBA units are designed to provide a limited supply of breathable air, and a low air gauge indicates that the air supply is dwindling, which can lead to a dangerous situation if not addressed promptly.

Exiting the hazardous area allows the firefighter to securely breathe fresh air and reassess the situation without the risk of running out of air. Maintaining situational awareness and prioritizing personal safety is imperative in emergency situations where the air quality may be compromised. Remaining in the hazardous area while air supply is low increases the risk of suffocation or loss of consciousness, greatly endangering the firefighter's life.

Actions such as proceeding without concern, checking with a buddy, or continuing to work to complete the task do not adequately address the imminent danger posed by limited air supply and could lead to serious consequences.
