PASS It On – Fire Extinguisher Safety

A fire extinguisher is an important part of any home or workplace safety plan, but knowing which one to choose and how to use it correctly is just as important as having one on hand. A little knowledge goes a long way in helping you stay prepared.

Fire extinguishers are meant for small, contained fires. They should not be used if the fire is spreading rapidly or putting you in danger. Use a fire extinguisher only if:

  • The fire is small and controllable
  • You have the correct extinguisher for the type of fire
  • The extinguisher is nearby, fully charged, and ready to use
  • You have a safe and clear exit in case conditions worsen

If the fire is too large, growing quickly, or you feel unsafe, leave immediately. Close the door behind you to slow the fire’s spread and call 911.

Fire Extinguisher Classes

Extinguishers are labeled according to the type of fire they are designed to fight. Using the wrong one can make the situation worse:

  • Class A (triangle symbol) – For ordinary materials like wood, paper, fabric, and some plastics
  • Class B (square symbol) – For flammable liquids such as gasoline, oil, grease, or paint
  • Class C (circle symbol) – For electrical equipment, outlets, appliances, and wiring
  • Class D (star symbol) – For combustible metals, most often found in industrial or lab settings
  • Class K – For cooking oils and fats, often used in commercial kitchens

Many extinguishers are designed for multiple uses, such as ABC models (common in homes) or BC models (often found in garages and kitchens).

Choosing the Right Extinguisher

Each extinguisher has a rating that shows its firefighting capacity—the higher the number, the larger the fire it can handle. Keep in mind that larger extinguishers are heavier, so choose one you can manage easily. Always look for extinguishers tested and approved by recognized organizations like UL (Underwriters Laboratories) or FM (Factory Mutual).

How to Use a Fire Extinguisher: The PASS Technique

If you need to use a fire extinguisher, remember PASS:

  • Pull the pin
  • Aim low, pointing the nozzle at the fire’s base
  • Squeeze the handle to release the agent
  • Sweep side to side until the flames are out

Even after the fire appears out, watch carefully for re-ignition. If the extinguisher empties and the fire is still burning, evacuate right away and call 911.
