Extinguisher Sizes Extinguishers are also rated for the size of fire they can handle. This rating will also appear on the label. The larger the numbers, the larger the fire that the extinguisher can put out, but higher-rated models are often heavier. Make sure you can hold and operate an extinguisher before you buy it. Installation and Maintenance Extinguishers should be installed in plain view, above the reach of children, near an escape route, and away from stoves and heating appliances.
Extinguishers require routine care.
Read you operator's manual to learn how to inspect your extinguisher. Follow manufacturer's instructions for maintenance. Rechargeable models must be serviced after every use. Disposable fire extinguishers can only be used once and must be replaced after use. To Use Remember the PASS word.
