What is the recommended action when exit routes are compromised by smoke?

When exit routes are compromised by smoke, the recommended action is to defend in place. This approach emphasizes the importance of safety when evacuation is not immediately possible. The principle behind defending in place is to seek a safe area within the building where individuals can remain until it is safe to evacuate or until help arrives. This may involve sealing doors and windows to protect against smoke ingress and staying low to the ground where air quality may be better.

Defending in place is advisable when the smoke is dense and visibility is poor, as rushing toward compromised exits can lead to disorientation and panic. It allows individuals to stay safe while emergency responders address the situation, making it a strategic choice rather than immediately evacuating through dangerous conditions.

While other options revolve around methods of evacuation or protective measures, in environments where smoke heavily obstructs exit routes, defending in place provides a plan that maximizes safety.
