In fire service operations, what does GPM stand for?

In fire service operations, GPM stands for Gallons Per Minute. This measurement indicates the flow rate of water from a fire pump or other water supply source. Understanding GPM is crucial as it directly influences a firefighter's ability to effectively combat a fire. The flow rate determines how quickly and how much water can be delivered to extinguish flames or to support firefighting efforts. A higher GPM typically means a more effective firefighting response, given that adequate water flow can significantly impact the ability to suppress a fire and protect lives and property.

The other options do not represent standard terminology used in fire service or hydraulic calculations, making them irrelevant in this context.
