Fire Extinguisher Operation
There are two main types of
fire extinguishers
,
carbon dioxide
dry chemical (powder)
Often, but not always, they carry different colors.
In this case the carbon dioxide extinguisher is red, and the dry-chemical (powder) extinguisher is yellow.
Read the tag to know which you will use. The tag also should show the date the extinguisher was last serviced.
Carbon dioxide extinguishers are good,
general purpose
extinguishers.
Dry-chemical (powder) are used for difficult cases, say certain types of electrical fires.
AVOID
using a dry-chemical extinguisher on a fellow human being.
The powder may get in the victim’s eye and cause irritation.

The fire, lacking oxygen, should go out.
