NHSA Module 5 Practice Test

The technique tested focuses on the proper way to operate a fire extinguisher in four steps that directly attack the fire. First, pull the pin to break the tamper seal and prepare the extinguisher to discharge. Then, aim the nozzle at the base of the fire, not at the flames, so you target the fuel source. Next, squeeze the handle to release the extinguishing agent. Finally, sweep the nozzle from side to side at the base of the fire to cover the area and push the fire back until it’s out. This sequence ensures you control the discharge, reach the fuel source, and sweep the entire area to extinguish it. Pushing the extinguisher toward the fire and spraying isn’t correct because the goal is to hit the base, where the fuel is, not chase the flames. Using a light spray doesn’t provide enough agent or coverage to reliably knock down the fire. And waiting for others to respond without attempting the proper steps misses the opportunity to control a small fire early, if it’s safe to do so.
