When selecting a fire extinguisher, one must be familiar with the classes of fires and the fire loading in order to provide the appropriate type of extinguisher.
Classes of Fire
The following descriptions of the classes of fires will help determine what type of extinguisher is needed to extinguish a specific type of fire.
Class A fires involve ordinary combustible such as paper, cloth, wood, rubber and some plastics.
Class B fires involve flammable liquids such as gasoline, thinners, oil-based paints and greases.
Class C fires involve energized electrical equipment such as computers, copy machines, television sets and video equipment.
Class D fires involve combustible metals such as magnesium, titanium, zinc and potassium.
Class K fires involve kitchen fires that contain cooking oils, and greases.
Fire Loading
The following is a description of the three degrees of fire loading within the occupancy.
Light (Low) Fire Load: An Occupancy in which Class A combustible materials including furniture, window treatments and its contents is of minor quantity. Small amounts of Class B flammable liquids such as duplicating and cleaning solvents are included provided that they are kept in closed containers and stored properly.
Ordinary (Moderate) Fire Load: An occupancy in which Class A combustibles, Class B flammable liquids and Class C energized electrical equipment are in greater amounts than expected under a low hazard. These locations include dining areas, storage areas and parking garages and assembly halls.
Extra (High) Fire Load: An occupancy in which the total amount of Class A combustibles, Class B flammable liquids and Class C energized electrical equipment present is over and above those classified as moderate hazard. Theses occupancies and areas include laboratories, cooking areas, trade shops and warehouses.
Pressurized Water: The pressurized water extinguisher is the most popular type of extinguisher used for extinguishing Class A fires.
Carbon Dioxide: The carbon dioxide fire extinguisher is primarily used in areas where the potential for Class B and Class C fire loads exist.
Multi-Purpose Dry Chemical: The dry chemical fire extinguisher is used in areas where Class A, Class B or Class C hazards are encountered.
Extinguishing Agents for Combustible Metals: There is no single extinguishing agent or powder that will control or suppress all combustible metal fires. The type of extinguishing agent in a particular area is based on the type of combustible metals being used.
All fire extinguishers shall have a label affixed to the front of the extinguisher showing operating instructions and the extinguisher rating.
A pictogram or letter-shaped symbol can be used for identifying the extinguisher's rating.

All portable fire extinguishers shall be installed on brackets or mounted in wall cabinets. Extinguishers having a gross weight not exceeding 40 pounds shall be installed so that the top of the extinguisher is not more than five feet from the floor. Extinguishers having a gross weight exceeding 40 pounds shall be installed so the top of the extinguisher is not more than three and one half feet above the floor. The bottom of the extinguisher in either case shall not be less than four inches above the floor.
Where the extinguisher is likely to be obscured, a sign shall be installed marking the location of the fire extinguisher. The sign shall be visible from a distance of at least 50 feet if the extinguisher cannot be relocated.
