Class D Fire Extinguishers

Inspection & Installation in Houston

If you own a laboratory or industrial facility in the Houston area, your building could house flammable metals such as magnesium, sodium, titanium, potassium, uranium, calcium and lithium. If so, you must incorporate the appropriate fire protection equipment in case a blaze breaks out.

Class D fire extinguishers are designed to fight these exact types of fire. For installation or inspection services of Class D fire extinguishers in the Houston area, call Kauffman Co. today at 713-893-1090!

Class D Fires

With the exception of sodium and other metals that burn in contact with air or water, large chunks of combustible metals don’t present an extraordinary fire risk under ambient conditions because they naturally conduct heat away from hot spots. This means the heat required for combustion is almost impossible to maintain unless the conditions are very, very hot.

Combustible metals are most likely to ignite when thin shavings or dust called “metal fines” are combined with sawdust. This type of debris can be left over after a machining process, and a spark is all it takes to ignite a fire.

Class D Fire Extinguishers

Combustible metal fires require a Class D fire extinguisher to douse the blaze. Water and other common fire fighting methods can make metal fires worse.

Class D fire extinguishers use dry powder agents to smother the flames and absorb heat. Don’t confuse ordinary “dry chemical” extinguishing agents with “dry powder” used in Class D fire extinguishers. Dry chemicals can actually aggravate Class D fires. Sodium carbonate, sodium chloride, bicarbonate, graphite and salt-based chemicals are most commonly used to extinguish metal fires.

Using a Class D Fire Extinguisher

Because metal fires are rare outside of laboratories or industrial buildings, people often underestimate their potential to burn rapidly and spread surprisingly quickly to other ordinary combustible materials in the room. Therefore, industrial workers in facilities with combustible metals should be educated on the importance of Class D fire extinguishers and know how to use them properly.

When you purchase a Class D fire extinguisher from Kauffman, Co., remember to schedule a training session so your entire staff can become comfortable with the equipment should a dangerous situation occur at your facility. Basic firefighting skills can reduce damage from a fire, shorten your facility’s recovery time and even save lives.
