Not all extinguishers are created equal. In fact, there are different fire extinguisher classes designed to put out various types of fires. If flames break out in your home, office, or other building with ordinary combustible products, flammable liquids, and electrical wiring, a multipurpose ABC fire extinguisher is the proper tool to douse the blaze.

For cooking fires in commercial kitchens, a Class K extinguisher is needed to put out the fire and prevent it from reflashing. Class D extinguishers are less common and are only used to fight fires that break out in chemical plants and industrial facilities with combustible metals onsite, such as sodium, potassium, titanium, and magnesium.

If your building features fire sprinklers, chances are good you also need a fire pump. This machine ensures every sprinkler in the building receives enough water to extinguish a fast-growing blaze. If the pressure drops, the fire pump turns on automatically to increase the water flow to an adequate level.

Water pressure is most likely to be a problem in high-rises, large buildings, and structures with ground-level water tanks. These types of properties need fire pumps the most, though we install them in other buildings as well.
