Ratings for Fire Extinguishers

October 6, 2010

Have you ever wondered why portable dry chemical fire extinguishers have an A, B or C or BC or ABC letters on the labels?

It has to do with the class of fire that the extinguisher will extinguish.  An “A” rated extinguisher is best used on wood, paper, rubber and plastic fires.  A “B” extinguisher is for flammable liquids, gases and greases.  A “C” extinguisher is for electrical fires.

Normally you will see a “BC” extinguisher, which will work for liquids and electrical.  Our philosophy is that for a couple of pennies more, you can have a TriClass ABC extinguisher that will handle all classes of that potential fire.  We sell four different TriClass extinguishers – 2-1/2 lb, 5 lb, 10 lb, and 20 lb.

Roofers should always have an extinguisher on their job site.  Keep one by the kettle and a couple on the roof for those hot jobs.  Any torch down modified jobs should have a couple because you have an open flame on the roof.  And then, those TPO jobs should have a couple on the roof in case of an electrical or debris fire.

We always work toward a safe work environment, but sometimes things happen on the job site.  Be prepared.
