North Carolina Fireground Operations 8 Practice Test

Adjustable-gallonage fog nozzles are built to offer a few discrete flow settings so you can tailor water application to the fire and conditions. For many models, the selectable gallonages are 60, 95, and 125 gpm. That means the nozzle can be set to flow 60, 95, or 125 gallons per minute, depending on what the situation calls for. This flexibility helps you manage heat, steam production, and water damage by choosing a lower flow for initial attack or a higher flow for rapid knockdown on larger fires. Flows like 300 gpm aren’t supported by these nozzles, and a setting that only allows 60 gpm would miss the practical benefits of adjustable gallonage. So the statement is true.
