What must be done when a member is trapped or entangled?

When a member is trapped or entangled, initiating buddy breathing to exit is a crucial procedure. This technique allows trapped firefighters to share breathing air with their partner, ensuring that both have sufficient oxygen while attempting to extricate themselves from the dangerous situation. Buddy breathing can also provide a measure of psychological reassurance during a stressful and potentially life-threatening scenario. By working together, the individuals can effectively coordinate their efforts to free the trapped member while maintaining vital air supply.

The other options present less effective responses to being trapped. Simply waiting for help to arrive can lead to further complications, including exposure to smoke or toxic gases, and delays in rescue efforts can escalate danger. Using emergency breathing techniques is important when managing air supply, but in the context of being trapped or entangled, it may not facilitate a quick escape. Calling for a backup team is a necessary step in some scenarios; however, it also requires waiting and does not immediately address the urgent need to help the trapped individual. Each situation varies, but initiating buddy breathing represents an immediate and proactive approach to tackling the situation at hand.
