What is the primary goal of using a deck gun during a fire response?

The primary goal of using a deck gun during a fire response is to extinguish large fire areas quickly. Deck guns are mounted on fire apparatus and are designed to deliver a significant volume of water over a wide area, making them particularly effective for tackling large-scale fires such as those found in commercial buildings, warehouses, or brush fires. Their ability to project water at a high flow rate allows firefighters to suppress flames quickly, reducing the overall damage and preventing the fire from spreading further.

In contrast, the other options do not align with the primary function of a deck gun. Filling fire trucks with water is a necessary task, but not the objective of deploying a deck gun. Increasing the weight of equipment has no relevance to firefighting strategies, and creating a firebreak is a tactic used primarily in wildland firefighting, which is not the main use for deck guns that are typically employed in structural firefighting scenarios. Thus, focusing on quickly extinguishing fires is the main purpose of using a deck gun.
