If experiencing symptoms of oxygen deficiency while on SCBA, what should you do?

When experiencing symptoms of oxygen deficiency while using a Self-Contained Breathing Apparatus (SCBA), the most appropriate action is to report by radio and evacuate immediately. This decision is crucial for several reasons.

First, oxygen deficiency can lead to severe consequences, including loss of consciousness and impaired decision-making. If a firefighter starts to show symptoms, it indicates that the breathing environment may be hazardous, and staying in that environment could result in further complications or incapacity.

Additionally, reporting the situation allows command to be aware of any problems in the field, which may help provide assistance to the affected personnel and ensure that appropriate safety measures are enacted for the overall safety of the crew. Evacuating immediately is critical, as it prioritizes the safety of the individual experiencing symptoms and potentially allows them to receive medical assistance if needed.

In contrast, options like continuing to work or taking a break are risky, as they could lead to further exposure to the harmful environment. Staying low to the ground may provide some temporary relief because gases tend to rise, but without addressing the oxygen deficit and moving to a safe atmosphere, the situation remains dangerous. Therefore, promptly reporting and evacuating is the best course of action to safeguard personal safety and maintain operational integrity.
