Fire Extinguisher Rules

Fires occur in homes and businesses every day. However, when fire extinguishers are present, the prepared user can help minimize the damage. While there are a few laws governing the use of fire extinguishers, there are also rules that help the operator know how to place, maintain, prepare and operate fire extinguishers. With some intentional planning, you can be ready for a fire at any time.

  1. Where to Place Fire Extinguishers

    • Place fire extinguishers at key locations throughout the workplace or home. However, always place some fire extinguishers close to an exit. This will help provide a way of escape if a fire becomes uncontrollable.

    Types of Fire Extinguishers

    • There are several different types of fire extinguishers, based on the materials that can cause fires. Extinguishers are classified into different categories: a Class A extinguisher can put out rubber, paper, plastic, wood and cloth fires. Class B extinguishers work with flammable liquids, like gasoline, grease, oil-based paints and other oils. Class C extinguishers are intended for anything plugged into an electrical outlet, whether appliances, tools or equipment. Class D extinguishers work for flammable metals; usually, they are specific to a certain kind of flammable metal. The final type, Class K extinguishers, are intended for commercial kitchens, extinguishing fires caused by vegetable and animal oils or fats. Only use a fire extinguisher for the specified type of fire; extinguishers are typically labeled as "A-B-C" or "B-C" to help the user determine the use.

    Maintenance of Fire Extinguishers

    • You should check fire extinguishers regularly and examine them once a year. Every few years, perform a pressure test to ensure that the extinguisher is safe for use.

    Before Using a Fire Extinguisher

    • You should only use a fire extinguisher after you have completed other fire safety steps. In a fire, pull the fire alarm, ensure everyone is evacuating the building, call 911 and stay low. Before using a fire extinguisher, make sure that there is a clear path to the exit and you know how to use the extinguisher. In addition, only use a fire extinguisher if the room is not filled with smoke and if the fire is confined to a small area.

    Using a Fire Extinguisher

    • Operating a fire extinguisher requires four steps, remembered by the acronym PASS. To use, pull the pin and hold the nozzle away from your body. Aim the extinguisher low, to the base of the fire. Squeeze the extinguisher's lever evenly and slowly to ensure even distribution, and sweep the nozzle from one side to another.
