When it comes to fire safety, a fire extinguisher is your first line of defense. But not all fire extinguishers are the same, and understanding the differences could make all the difference in an emergency. Those letters—A, B, C, D, and K—aren’t just alphabet soup; they’re a code to ensure you’re using the right tool for the right type of fire.
Let’s break down the types of fire extinguishers, what those letters mean, and how to use them effectively.
The ABCs of Fire Extinguishers
The letters on fire extinguishers indicate the types of fires they are designed to combat. Each letter corresponds to a category of fire:
- Class A: Ordinary Combustibles
- Includes wood, paper, cloth, and most plastics.
- Example: A trash can fire or burning curtains.
- Best Extinguisher: Water-based or multi-purpose extinguishers labeled A.
- Class B: Flammable Liquids
- Includes gasoline, oil, paint, and other combustible liquids.
- Example: A grease spill ignites in the garage.
- Best Extinguisher: CO2 or dry chemical extinguishers labeled B.
- Class C: Electrical Fires
- Includes fires involving electrical equipment like appliances, wiring, or circuit breakers.
- Example: A short circuit sparks a fire in the office.
- Best Extinguisher: Non-conductive extinguishers like CO2 or dry chemical labeled C.
- Class D: Combustible Metals
- Includes magnesium, titanium, and other reactive metals.
- Example: Fires in industrial or manufacturing settings.
- Best Extinguisher: Specialty extinguishers labeled D (typically found in industrial settings).
- Class K: Kitchen Fires
- Includes cooking oils and grease fires in commercial or residential kitchens.
- Example: An overheated frying pan catches fire.
- Best Extinguisher: Wet chemical extinguishers labeled K.
The Case for Early Intervention
A startling statistic reveals that in incidents where a fire extinguisher is used, the fire department is not required to attend 75% of the time (ICW2019). This underscores the importance of early intervention—having a fire extinguisher within reach can often mean the difference between a minor mishap and a full-scale disaster.
Cooking fires are a prime example. As the leading cause of household fires and injuries, nearly half of all home cooking fires are caused by fat, grease, or oil (FEMA). Without the right extinguisher (such as a Class K for grease fires), these incidents can escalate quickly.
Despite the critical role extinguishers play, a survey revealed that 28% of respondents do not have a fire extinguisher in their home (SelectSafety). This gap in preparedness is a stark reminder that many families are unprepared to handle a fire emergency.
How to Use a Fire Extinguisher: The PASS Method
Once you have the right extinguisher, knowing how to use it is critical. Follow the PASS method:
- Pull the pin to unlock the extinguisher.
- Aim low at the base of the fire.
- Squeeze the handle to release the extinguishing agent.
- Sweep from side to side, continuing until the fire is out or the extinguisher is empty.
When NOT to Use a Fire Extinguisher
Fire extinguishers are incredibly useful, but they aren’t a one-size-fits-all solution. You should never use one if:
- The fire is too large or spreading quickly.
- You’re unsure of what type of fire it is.
- You don’t have a clear escape route.
In these cases, evacuate immediately and call 911.
Choosing the Right Extinguisher for Your Space
- Home: Opt for a multi-purpose ABC extinguisher.
- Kitchen: Add a Class K extinguisher for grease fires.
- Garage/Workshop: Include a Class B extinguisher for flammable liquids.
- Office: Have ABC extinguishers easily accessible near electrical equipment.
