What should other firefighters do while the fire suppression team is getting ready to apply water to the fire compartment?

Keeping the doors and windows closed is considered the best approach while the fire suppression team prepares to apply water to the fire compartment. This strategy helps to limit the amount of oxygen entering the space, which can reduce the chances of fire intensification and prevent flashover, a dangerous and rapid spread of fire that can occur with sudden influxes of oxygen. By maintaining a sealed environment, there is also a greater potential for more effective water application, allowing firefighters to control the fire more efficiently when they do make their entry.

In contrast, breaking windows and forcing doors open can unintentionally increase airflow to the fire, potentially worsening the situation. Natural or horizontal ventilation methods might also lead to a rapid increase in fire behavior and complicate the suppression efforts. Therefore, keeping the doors and windows closed is a strategic choice to enhance firefighter safety and increase operational effectiveness during the initial phase of firefighting efforts.
