    Aerosol fire sprays no substitute for extinguishers

    Consumer Reports News: April 07, 2010 02:33 PM

    You might be tempted to buy one of those aerosol fire sprays now sold in supermarkets but doing so could give you a false sense of security. Despite their claims, the aerosol sprays are not a substitute for a home fire extinguisher. Far from it.

    In fact, in our recent tests of fire extinguishers and sprays, we judged the First Alert Tundra and the Shield Fire Protection Kitchen Guard as: Don't Buy: Performance Problem. The sprays sometimes made the grease fire in our tests flare up before they put it out. That could cause the fire to spread or prompt the user to stop spraying the fire.

    Unlike the extinguishers we tested, neither spray has a pressure indicator that shows whether the unit is ready for use. As we reported in the May issue of Consumer Reports magazine, home fires are often unpredictable, and can be deadly. That's why you need one full-floor, multipurpose fire extinguisher on each level of your home and one in your garage, plus smaller, supplemental units for the kitchen and car.

    We tested 13 fire extinguishers and two sprays. (Ratings for subscribers.) No matter which fire extinguisher you buy, make sure its pressure indicator shows "full" and that it was manufactured within the last year. The National Fire Protection Association recommends that dry chemical extinguishers that are intended to be discarded after use should be disposed of 12 years after the date of manufacture. When buying an extinguisher, it's important to read the label.

    The NFPA recommends remembering the word PASS when operating an extinguisher. It means:

    • Pull the pin. Hold the extinguisher with the nozzle pointing away from you, and release the locking mechanism.
    • Aim low. Point the extinguisher at the base of the fire.
    • Squeeze the lever slowly and evenly.
    • Sweep the nozzle from side-to-side.
