What does 'decreased endurance' indicate for SCBA users in a hazardous environment?

Decreased endurance for SCBA (Self-Contained Breathing Apparatus) users in a hazardous environment signifies that fatigue may occur more quickly. When firefighters are wearing SCBA, the physical demands increase due to the weight of the equipment and the exertion necessary to perform their duties. This situation can lead to rapid fatigue, which diminishes their ability to work effectively and safely.

Understanding that endurance impacts performance is critical in emergencies where every second counts. It’s essential for firefighters to be conscious of their stamina when working in environments that require SCBA, as their ability to respond and operate effectively can be compromised if they tire more quickly than expected. Recognizing signs of fatigue helps ensure the safety of both the firefighters and the individuals they are trying to rescue.
