Which factor is NOT a primary factor in selecting a nozzle for a given fire scenario?

Explanation:
Choosing a nozzle is driven by how far the water must reach, what flow you can deliver from the available water source, and safety considerations for crews and exposures. The distance to target dictates the needed reach and the appropriate pattern and pressure to maintain control at that distance. The water source sets the maximum achievable flow and the discharge pressure you can realistically maintain, so the nozzle must be compatible with what the pump and supply can support. Safety considerations—such as protecting firefighters, occupants, and exposures and avoiding unnecessary risk—also guide nozzle choice. The color of the nozzle head does not affect reach, flow, pattern, or pressure, and thus isn’t a factor in selecting a nozzle.
