Also, the extinguisher must be labelled as to the type of fire it can extinguish. Make sure that you use the correct type of extinguisher for the fire you are fighting. Numbers are also used with letters for extinguishers labelled for class A and B fires. The larger the number, the larger the fire the extinguisher can put out. When purchasing fire extinguishers and smoke alarms, look for the Underwriters' Laboratories of Canada Label.
Extinguishers require regular care.
Read your operator's manual and contact your dealer for inspection and servicing information. Recharge reusable models after every use, and remember that you can only use disposable fire extinguishers once. Replace them after use. Place them in readily accessible locations, preferably near a doorway, where you can reach them without having to enter the fire area, and where you can fight the fire while remaining near an escape route. Contact the Fire Department for further advice on the best locations.
