Which Extinguisher To Use
Fire extinguishers are divided into four categories, based on different types of fires. The following is a quick guide to help choose the right type of extinguisher.
Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics.
Class B fires involve flammable or combustible liquids such as fuel, kerosene, grease and oil.
Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class C fires - the risk of electrical shock is far too great! The C classification means the extinguishing agent is non-conductive.
Class D fire extinguishers are commonly found in a chemical laboratory. They are for fires that involve combustible metals, such as magnesium, titanium, potassium and sodium. - they are designed for class D fires only.
