Fire Extinguisher 101
At LMC Fire and Security, we believe in equipping our clients with the tools required to respond to emergencies quickly and safely. Establishing a fire-safe business begins with identifying fire hazards, installing appropriate fire extinguishers throughout the facility, and scheduling routine inspections to avoid surprises during an emergency.
Not All Fires Are Created Equal
To determine which fire extinguisher is appropriate for your business, first identify the type (or class) of fire you may encounter.
Class A: Organic combustibles (coal, paper, and wood)
Class B: Flammable liquids (alcohol, gasoline, and paint)
Class C: Electrical fires (computers, tools, and appliances)
Class D: Flammable metals (lithium, magnesium, and titanium)
Class K: Fires involving cooking with oils, fats, and grease.
Recognizing the source of the fire and adequately preparing your business with the correct extinguisher is critical. For example, a water-based extinguisher can effectively extinguish a Class A fire. However, the same extinguisher would act as a conductor, fueling a Class K fire.
Choosing The Correct Fire Extinguisher
LMC Fire & Security recognizes the importance of regular maintenance testing and inspection. With our in-depth routine inspections, we ensure that all devices operate smoothly and consistently, so you can have confidence in your systems for years to come.
