Clean agent fire extinguishers are gaseous, electrically non-conductive fire suppressants that evaporate without leaving any residue behind. These fast-acting agents work in the early stages of a fire by reducing the oxygen available to the flames. Clean agent extinguishers are effective on Class A, B, and C fires and are commonly used in areas with sensitive materials, such as server rooms and museums.
These extinguishers can contain a variety of chemicals, including halocarbons and inert gases. The chemicals are stored in a pressurized cylinder in liquid form and are released as a gas when needed. These agents are more environmentally friendly than other options and are non-toxic to occupants.
