Fire extinguishers are your first line of defense in case of a small fire on the jobsite. But having one nearby isn’t enough — you need to know what type to use and how to use it correctly.
Why It Matters:
Using the wrong type of extinguisher can make a fire worse, not better. Every second counts in an emergency, and proper use of the right extinguisher can save lives, prevent injuries, and protect property.
Key Points:
- Know the Classes:
- Class A – For ordinary combustibles (wood, paper, cloth).
- Class B – For flammable liquids (fuel, grease, oil).
- Class C – For electrical fires.
- Class D – For flammable metals (rare on most jobsites).
- Class K – For cooking oils and grease (mainly in kitchens).
- Multi-class (ABC) extinguishers are common on construction sites and handle most hazards.
- PASS method for using extinguishers:
- Pull the pin.
- Aim at the base of the fire.
- Squeeze the handle.
- Sweep side to side.
- Inspect extinguishers monthly: check the gauge, ensure it’s charged, accessible, and not damaged.
✅ Right extinguisher, right technique — stop the fire fast.
Ask the Crew:
- Do we know which extinguishers are on-site and where they are?
- Have we been trained on the PASS method?
- Is someone checking the extinguishers regularly?
