Question 1 of 27070

When using a dry chemical fire extinguisher to fight a fuel oil fire, you should __________.

🔍 Key Concepts

• Class B (flammable liquids) fires and appropriate extinguishing techniques • How dry chemical extinguishers work to smother and interrupt the chemical chain reaction • Wind direction and position of the firefighter relative to smoke and vapors

💭 Think About

• Think about how to cover the largest possible area of burning fuel with the dry chemical so the flames are smothered effectively. • Consider what happens if you concentrate the agent in just one spot versus moving it over the surface of the burning liquid. • Ask yourself how wind direction affects where the agent goes and how much of it actually reaches the fire.

✅ Before You Answer

• Verify which technique gives maximum coverage over the burning fuel surface. • Check which option matches standard Class B fire-fighting procedures with portable extinguishers. • Eliminate any option that would cause you to lose effective control of the extinguisher or reduce the reach of the chemical agent.
