How to Pick and Use a Fire Extinguisher
Updated: Oct 30, 2020
Part of being your own first responder means having the right tools to respond to an emergency. An often overlooked tool to have is a fire extinguisher. US Fire Administration has already identified 1313 residential fire related fatalities from Jan 1, 2020 to August 11, 2020. That doesn't include places or work.
There are 5 different types of portable fire extinguishers:
Class A fire extinguishers are for normal flammable materials such as wood, paper, and some plastics.
Class B fire extinguishers are used with flammable liquids like oil and fuels.
Class C fire extinguishers are used on fires generated by electrical equipment.
Class D and Class K fire extinguishers are specialty use, and not common to find in a home
Class D fire extinguishers are for combustible metals like magnesium and titanium.
Class K fire extinguishers are for kitchen fires with grease, fats, and cooking oils.
The most common units you will find are combination ABC. These will cover most of the common fires you'll encounter in a home, office, or garage. These combination extinguishers are available at almost all home improvement or hardware stores, and most big box stores like Walmart and Target.
How to Size a Fire Extinguisher:
Fire extinguishers have a rating system that can be used to determine their capacity for fighting a fire. For a common ABC can, the rating is taken from the number next to the B. It will be listed on the outside of the canister in this format: 2-A: 40-B:C. This number correlates to the square footage of flames that can be extinguished. Keep in mind that's SQUARE footage. A 10ft x10ft square is 100 square feet.
Estimate the size of the room and what combustibles you have when you are looking for a fire extinguisher. In the kitchen you might just need enough to cover an area the size of a stove top, but in a garage, you might need an area that includes a work bench, or boxes of decorations. A fire extinguisher in your bedroom might just need to be big enough to create a small clearing to escape.
How to use a fire extinguisher:
When using a fire extinguisher use the acronym P.A.S.S.
Pull. Aim. Squeeze. Sweep.
PULL the Pin.
AIM at the BASE of the fire.
SQUEEZE the lever or trigger of the extinguisher.
SWEEP from side to side.
