Choosing the Right Fire Extinguisher
A fire extinguisher can be a lifesaver. Placed near an exit, in an easy-to-grab spot, it can put out a small fire before the firefighters arrive, or at least suppress the flames while you escape.
All household extinguishers are classified A, B, or C (or a combination of these) on the label to indicate which types of fires — ordinary combustibles, flammable liquids, or electrical—you can use them on. Many of the ones sold at home stores are classified A:B:C and fight all three types of fires.
The National Fire Protection Association (www.nfpa.org) recommends an extinguisher for each floor of your home.
The main distinction among home extinguishers is size. In most cases bigger is better, but sometimes the biggest extinguishers are too heavy to maneuver. (The weight on an extinguisher refers to the amount of chemical inside; the canister adds several more pounds.) There’s also a difference between rechargeable extinguishers, with metal valves, and disposable ones, which have plastic valves. A rechargeable one will cost more, but refilling it once the pressure gauge shows that use or time has depleted the contents is still less expensive than buying a new disposable one.
~Long after the cheap price is forgotten, the poor quality remains~
- 10-pound – Best for: Garage or home workshop, where a fire might grow in size before being noticed.
- 5-pound – Best for: Quick grab in the kitchen or laundry room, campers, boats
- 2.5 -pound (if a 5-pound will not fit) -Best for: Car.
Water and Foam Fire Extinguisher
Water and Foam fire extinguishers extinguish the fire by taking away the heat element of the fire triangle. Foam agents also separate the oxygen element from the other elements. Water extinguishers are for Class A fires only
Dry Chemical Fire Extinguisher
Dry Chemical Extinguishers extinguish the fire by interrupting the chemical reaction of the fire triangle. They are most effective on Class A, B and C fires
CO2 Fire Extinguisher
Carbon Dioxide Extinguishers take away the oxygen element of the fire triangle. They also remove the heat with a cold discharge. They can be used on Class B and C fires.
Clean Agent Extinguisher
Clean Agent Extinguishers extinguish the fire by interrupting the chemical reaction of the fire triangle.
Clean agent extinguishers are primarily for Class B & C fires. Some larger clean agent extinguishers can be used on Class A, B, and C fires.
Wet Chemical is a new agent that extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements.
Wet chemical of Class K extinguishers were developed for modern, high efficiency deep fat fryers in commercial cooking operations. Some may also be used on Class A fires in commercial kitchens.
Dry Powder extinguishers are similar to dry chemical except that they extinguish the fire by separating the fuel from the oxygen element or by removing the heat element of the fire triangle.
However, dry powder extinguishers are for Class D or combustible metal fires, only. They are ineffective on all other classes of fires.
