What is the name of the fire control method where the nozzle is opened for fire control and then shut down for advancement?

The fire control method referred to is "hit and move." This technique involves quickly applying water or another extinguishing agent to the fire with the nozzle opened to effectively manage the flames and heat. After achieving a certain level of control through this initial application, firefighters then move into position for further advancement, ensuring they are not in harm's way while making progress towards extinguishing the fire. This method allows for a dynamic response to fire conditions and enhances the safety of the firefighting crew by minimizing exposure during vulnerable times, such as when they are advancing through active fire areas.

The other options, while they may imply some form of tactical response, do not encapsulate the same strategy. "Spray and retreat" suggests a more passive approach that does not emphasize the advancement aspect. "Cool and hold" focuses on cooling a fire without progressing toward extinguishment or control. "Touch and go" implies a brief interaction rather than a strategic approach to controlling and advancing on a fire. Thus, "hit and move" is the most suitable choice for describing this specific firefighting technique.
