Objective:
To know how to identify the types of fire extinguishers and be able to properly use them.
Background:
Fire extinguishers can put out or control a fire until help arrives. Use portable units as first-aid or
emergency units on small fires or in the initial stages of the fire. The discharge time on most portable
units is only seconds, so plan an escape route. Stay low and avoid breathing the smoke and extinguishing
agent. If the fire starts to spread, GET OUT!
Selecting the Proper Fire Extinguisher:
The universal classification system has four designations for fire extinguishers: class A; B; C; D. Class
labels are based on the size of a fire to be extinguished and the contained extinguishing agent. A 20B
rating is recommended for non-expert user. Combination extinguishers are suitable for more than
one class of fire and are marked as such.
Class Symbol Type of Fuel
A
green triangle ordinary combustibles
B

C
