DID YOU KNOW?
The first fire extinguisher in 1723 used gunpowder to propel water onto flames — a far cry from today’s specialized options. [2] With multiple extinguisher classes, it’s essential to use the right type for the fire at hand.
KNOW THE RISK
- Different types of fires require different extinguishing agents. Using the wrong type of extinguisher can make a fire worse — or put the user in danger. [1]
- There are five primary fire extinguisher classes, each designed for a specific kind of material or hazard. [1]
- All portable fire extinguishers should have clear labeling showing the classes they are rated for. Look for these labels before an emergency happens. [1]
MITIGATE THE RISK
1. Class A – Ordinary Combustibles
- Use for fires involving paper, wood, cloth, rubber, and plastics. These are common in offices, homes, and workshops. [1]
2. Class B – Flammable Liquids
- Designed for gasoline, diesel, oil, grease, and paints. Never use water on a Class B fire. [1]
3. Class C – Electrical Fires
- Use on energized electrical equipment like wiring, panels, and appliances. Once de-energized, treat as a Class A or B fire. [1]
4. Class D – Combustible Metals
- Specifically made for metals such as magnesium, titanium, or sodium. Found in labs and manufacturing settings.
5. Class K – Cooking Oils and Greases
- Used in commercial kitchens for deep fryers and other high-heat cooking appliances. These extinguishers cool and suppress vapors to prevent re-ignition.
FIRE EXTINGUISHER REMINDER
Not all fires are the same — and neither are fire extinguishers. Train your team to recognize fire types and choose the right extinguisher for fast, effective, and safe response. When seconds matter, knowledge saves lives.
