Please remember extinguishers have limits; they are not for large fires because most last less than 30 seconds. When used properly a portable extinguisher can save lives and property by knocking down a small fire or containing one until the fire department arrives.
Portable extinguishers should be installed in plain view. Near an escape route, away from any heating appliances, and above the reach of children. It is very important to maintain your extinguisher because you want to know that it will work if the time comes that you may need to use it. Follow the manufacturer's instructions for maintenance.
There are four basic types of fire extinguishers. Each class of extinguisher will have an icon to indicate how a extinguisher should be used.
