While proper procedure and training can minimize the chances of an accidental fire, workers still must be prepared to deal with a fire emergency should it occur.
According to the National Fire Protection Association, there are four basic types of fire extinguishers in common use today. They are classified according to the type of fire they are capable of extinguishing:
1. Type A fire extinguishers are used for combustible solids (articles that burn) such as paper, wood and cloth. The symbol for a Type A fire extinguisher is a green triangle with the letter A in the center.
2. Type B extinguishers are used for combustible liquids such as oil, grease and paint thinner. The symbol for a Type B extinguisher is a red square with the letter B in the center.
3. Type C extinguishers are for use on electrical fires involving items such as fuse boxes, electric motors and welding machines. The symbol for a Type C extinguisher is a blue circle with the letter C in the center.
4. Type D extinguishers are used on fires involving combustible metals such as zinc, titanium and magnesium. The symbol for a Type D extinguisher is a yellow star with the letter D in the center.
