When documenting water usage during suppression, you should record...

• A. Line length, nozzle size, gpm or gpm estimate, and pump pressure.
• B. Color of PPE used.
• C. Time of day and weather.
• D. Only the total time spent.

Answer: (B)

Documenting water usage during suppression focuses on the hydraulic data you control on the line. You should record the line length deployed, the nozzle size, the flow rate (gpm or a reasonable estimate), and the pump discharge pressure. This combination lets you quantify water delivery and understand how much water was applied, how the hydraulic setup performed, and where improvements might be needed. The color of PPE used isn’t related to water usage, and while noting time of day, weather, or total time spent can be useful for broader incident records, they don’t provide the actual water usage data by themselves. So the most relevant documentation is the record that includes line length, nozzle size, gpm, and pump pressure.
