Significant health, safety, and environmental risks can result if untrained personnel attempt to work on the pressurized internal components of a fire extinguisher.
Proper inspection, maintenance, and disposal of fire extinguishers can prevent potentially dangerous malfunctions.
Fire extinguishers should be operated using the PASS technique: Pull out the safety pin, Aim the extinguisher at the base of the fire, Squeeze the handle, and Sweep the spray from side to side.
Class A fires involve ordinary materials that easily burn, such as paper, cloth, and some plastics. Class B fires are from flammable liquids such as gasoline, non-cooking oils, solvents, and alcohols. Class C fires involve electrical equipment such as appliances, computers, and power tools that are plugged into a live/hot electrical outlet. Class D fires include metal powders and shavings. Class K fires are due to cooking oils and grease used in deep fat fryers in commercial kitchens.
