You never want to have to use them, but it's wise to own several fire extinguishers. Used correctly, they'll reduce flame and smoke damage and may save your home--or your life. But not all fires are alike and using the wrong type of extinguisher will actually make things worse.

Instructions

Difficulty: Moderately Easy

Step1
Look for symbols or the letters A, B and C to determine which fire class(es) the extinguisher will put out. Class A extinguishers put out fires fueled by wood, paper, cloth, rubber and most plastics. Class B extinguishes flammable liquids, such as gasoline, oil and grease. Class C is for wiring, appliance and electrical fires.
Step2
Buy the most suitable extinguisher for each room. Keep one in the garage, and another near the furnace. In the kitchen, get a combination B-C extinguisher for grease and gas fires.
Step3
Check each extinguisher's number rating. The higher the number, the larger a fire the extinguisher can put out. (A 4-A unit will put out twice as much Class A fire as a 2-A one.) A high number usually means a big, heavy unit.
Step4
Select disposable or rechargeable models. Disposable units ($10 to $20) are typically made of plastic and lose pressure after about 12 years. Rechargeable extinguishers (up to $50) can be refilled after use and if they lose pressure. They should be serviced annually by the manufacturer.

What to Look For:

  • Relevant fire-class rating
  • High number rating
  • Manageable size and weight
  • Disposable or rechargeable

Tips & Warnings

  • Whatever class or size you choose, the extinguisher must be approved by Underwriters Laboratories (UL.com) or Factory Mutual (FMglobal.com).
  • Make sure you and other family members understand how to operate your home's fire extinguishers.
