The ABC's of Fire Extinguishers
Dry Chemical Extinguishers come in a variety of types. You may see them labeled:
- "DC" short for "dry chem"
- "ABC" indicating that they are designed to extinguish class A,B,and C fires, or
- "BC" indicating that they are designed to extinguish class B and C fires.
It is extremely important to identify which types of dry chemical extinguishers are located in your area.
Read the labels and know their locations!
You don't want to mistakenly use a "BC" extinguisher on a Class A fire, thinking that it was an "ABC" extinguisher.
An "ABC" extinguisher will have a label like this, indicating that it may be used on class A,B, and C fires.
Dry chemical extinguishers
put out fire by coating the fuel with a thin layer of dust, separating the fuel
from the oxygen in the air. The powder also works to interrupt the chemical reaction
of fire, so these extinguishers are extremely effective at putting out fire.
