How to Use a Fire Extinguisher Correctly (PASS 4 Method Explained)

How to Use a Fire Extinguisher properly could mean the difference between a minor incident and a major disaster. Whether you’re at home, at work, or in a public building, knowing how to respond swiftly and effectively when fire breaks out is a life-saving skill.

In this article, we’ll explain the PASS method—the globally recognized technique for using fire extinguishers safely and effectively.

Why Knowing How to Use a Fire Extinguisher Is Essential

Fire extinguishers are often the first line of defense when a fire breaks out. But owning one isn’t enough. You must also:

  • Know how to use it
  • Be trained in recognizing when it’s safe to use
  • Understand the different types of extinguishers
  • Avoid putting yourself or others in danger

Incorrect use can worsen a fire or delay evacuation. Training your team in basic fire extinguisher operation can help meet OSHA and OHSA standards.


Step-by-Step: The PASS Method

The PASS acronym is the simplest and most effective way to remember how to use a fire extinguisher.

How to Use a Fire Extinguisher

Here’s what it stands for:


P – Pull the Pin

The pin prevents accidental discharge. Pulling it unlocks the extinguisher so it can be activated.

Tip: Hold the extinguisher upright and aim away from your body as you remove the pin.


A – Aim at the Base of the Fire

Point the nozzle or hose at the base, not the flames. Fires are fueled from the bottom; extinguishing the flames alone won’t stop the fire from reigniting.

Tip: Stand about 6–10 feet away when aiming. Get closer only if it’s safe.


S – Squeeze the Handle

Squeeze the lever slowly and evenly to discharge the extinguishing agent. Release the handle to stop.

Tip: A short burst may help conserve the agent and allow more control.


S – Sweep from Side to Side

Move the nozzle side to side while aiming at the base. Continue until the fire is out.

Tip: Don’t turn your back on the fire. Watch for flare-ups and be ready to use the extinguisher again if needed.


Know When to Use an Extinguisher

Before attempting to extinguish a fire:

✅ Ensure the fire is small and contained (like a wastebasket)
✅ Have a clear exit behind you
✅ Make sure you’re using the right type of extinguisher
✅ The area should not be filled with smoke or toxic fumes

When NOT to use one:

  • The fire is spreading quickly
  • You don’t know what’s burning (especially chemicals)
  • You are unsure how to use the extinguisher
  • You can’t get to an exit if needed

Maintenance and Inspection Tips

Using a faulty extinguisher is dangerous. Monthly and annual checks should include:

  • Is it pressurized (check the gauge)?
  • Is the pin intact and secured?
  • Is it free of dents or corrosion?
  • Is it easily accessible (not blocked)?
  • Are employees trained?

Workplaces should also schedule annual inspections by a certified technician, as required by NFPA and local fire codes.


Emergency Tips

Even if the fire appears out:

🔥 Don’t leave the area unattended
📞 Call 911 or your local emergency number
🚪 Ventilate the area
⚠️ Get medical attention if you inhaled smoke

Conclusion

Knowing how to use a fire extinguisher using the PASS method can make you a workplace hero—or even save a life. Train your staff, place extinguishers strategically, and conduct regular drills to stay prepared.

Never forget: If you’re unsure, evacuate immediately and let professionals handle the fire.
