What should a person do when they reach 50% of their air consumption?

When a person reaches 50% of their air consumption, it is crucial for them to notify their crew. This action is important for several reasons. First, informing team members about their air status ensures that everyone is aware of the situation and can assess the overall readiness and safety of the crew. Firefighting environments are often unpredictable, and communication is vital for maintaining team safety and coordination.

By notifying their crew, the individual allows for proper planning to be put in place. This could involve examining the remaining tasks, evaluating the potential risks of continuing the operation, and deciding whether it is necessary to initiate an evacuation plan. Coordination becomes essential as the situation evolves, particularly in environments where visibility is limited, and conditions can become hazardous quickly.

Additionally, this communication may prompt the crew to check on their own air supply and assess whether they are approaching a critical level as well. Overall, notifying the crew fosters a collaborative safety culture within the team and can lead to more effective decision-making during operations.
