The term "reach" refers specifically to the distance that an extinguishing agent can be effectively projected from the nozzle of a firefighting device. In the context of Aircraft Rescue and Fire Fighting (ARFF), understanding reach is crucial for determining how far the agent can travel to effectively combat a fire and protect personnel and equipment.

Reach takes into account various factors including the type of extinguishing agent used, the design of the nozzle, and the pressure applied, all of which can influence how far the agent travels and its effectiveness upon arrival at the target. A firefighter needs to be aware of the reach to position themselves properly and select the appropriate tactics for fire suppression, especially in challenging scenarios often associated with aircraft fires.

The other terms, while related to firefighting, do not specifically capture this concept. "Range" is often used interchangeably in some contexts but is less precise than "reach." "Distance" is a more general term that does not specifically relate to extinguishing agents, and "coverage" typically refers to the area that can be covered by an extinguishing agent, rather than the distance it can travel from the nozzle.
