When should a master stream be initiated during a fire response?

The initiation of a master stream during a fire response is best done after exhausting all hand-line options. This approach ensures that firefighters first attempt to control the fire using smaller, more maneuverable hand lines, which allow for a more direct attack on the fire, minimizing collateral damage and maintaining safety for personnel.

Utilizing hand lines first is part of a strategic approach that allows for assessing the situation, determining the fire's behavior, and applying water directly where it is needed most. If these options fail to achieve control over the fire or if the situation escalates, then deploying a master stream becomes a necessary tactic. Master streams deliver large volumes of water from a distance and are effective in suppressing larger, more intense fires that hand lines might not be able to manage effectively.

This approach prioritizes firefighter safety and effective fire control, ensuring that resources are used efficiently and only escalated as necessary, which reflects sound tactical decision-making in fire response situations.
