Fire Rules
Never Fight a Fire if you don't know what is
burning
If you don't know what is burning, you don't know
what type of extinguisher to use.
Even if you have an ABC extinguisher, there may
be something in the fire which is going to explode
or produce highly toxic smoke.

Fire Rules
Never Fight a Fire if the fire is spreading
rapidly beyond the spot where it started
The time to use an extinguisher is in the incipient,
or beginning, stages of a fire. If the fire is already
spreading quickly, it is best to simply evacuate the
building, closing doors and windows behind youas you leave.

reason, just let the fire department do their job.

Fire Rules
The final rule is to always position yourself with
an exit or means of escape at your back before
you attempt to use an extinguisher to put out a
fire.
In case the extinguisher malfunctions, or
something unexpected happens, you need to be
able to get out quickly, and you don't want to become trapped. Just remember, always keep an
exit at your back.
