3 Tips for Using a Fire Extinguisher

9/23/2021 (Permalink)

Fire extinguishers are essential fire suppression equipment. Commercial building owners and occupants should know how to choose and safely use any fire extinguisher. Applying the right type of suppressant to open flames has the potential to minimize fire damage and safety risks during a fire at a commercial building in Rochester, NY.

1. Use the Right Extinguisher Class
There are five classes of fire extinguishers and commercial buildings may be equipped with one or more extinguisher types. Class A extinguishers contain suppressants for ordinary combustibles, while Class B extinguishers put out blazes fed by flammable liquids. Class K extinguishers are formulated for commercial kitchen fires. Class C extinguishers contain suppressants for electrical fires, and Class D extinguishers put out fires fueled by combustible metals.

2. Do the PASS Method
The PASS method is the best way to limit fire damage. Pull the pin, aim the fire extinguisher hose at the base of a blaze, squeeze the handle and sweep spray from side to side. Although this method puts out some fires, the force of the spray may spread grease fires. In these cases, dousing flames or limiting airflow may prove effective.

3. Plan Ahead for Evacuation
Before using an extinguisher, a building occupant should make sure that he or she will be able to safely evacuate the area if it is not possible to put out the flames. Anyone attempting to suppress a fire should exercise caution to prevent flames from blocking off the most convenient route out of a burning building.
These fire extinguisher tips are only helpful if a commercial building is equipped with the proper class and number of fire extinguishers. The fire hazard level of a structure will determine the number and positioning of extinguishers. Fire safety codes may require that extinguishers be spaced 30, 50 or 75 feet apart at a building in Rochester, NY.
