Clean agent fire extinguishers store agent as a liquid which turns to gas when it hits the air.

These are effective on Class A, B & C fires. It is primarily suited for 'B' and 'C' classes of fire but some large clean agent extinguishers can be used on class A, B and C fires. These extinguishers have zero global warming (or ozone depletion) potential.

Clean agent fire extinguishers will not conduct electricity to the user. Clean agent extinguishers act without thermal shock to delicate electronic equipment by cooling and smothering it the fire. They extinguish the fire by interrupting the chemical reaction of the fire.
