Portable extinguishers are also rated for the size of fire they can handle. The larger the number, the larger the fire that the extinguisher can put out. Higher-rated models are often heavier. Make sure you can hold and operate the extinguisher before you buy. Ask you local fire department for advice on the best locations.
Extinguishers require routine care.
Read your operator's manual and ask your dealer how your extinguisher should be inspected and serviced. Rechargeable models must be serviced after every use. Disposable fire extinguishers can be used only once, and must be replaced after use. Following manufacturer's instructions, check the pressure in your extingushers once a month. Follow the four-step PASS procedure.
