They are labeled clean agents because they do not leave any residue after discharge. These type are ideal for sensitive electronics and documents. Includes the following:

CO2 - Used with sensitive documents and electronics.

Halogen Type - Halon (including Halon 1211 and Halon 1301), a gaseous agent that inhibits the chemical reaction of the fire. Classes B:C for lower weight fire extinguishers (2.3 kg; under 9 lbs) and A:B:C for heavier weights (4.1–7.7 kg; 9–17 lbs). Banned from new production, except for military use, as of January 1, 1994 as its properties reportedly contribute to ozone depletion. Halon 1301 and 1211 are being replaced with new halocarbon agents and should be switched to new types of fire extinguishers. Currently Halotron I, Halotron II, FE-36 Cleanguard and FM-200 are replacements that may be used. Includes the following:

FE 36 Cleanguard- Clean, used for sensitive electronics and documents, and computer rooms..
Halotron i - Clean, used for sensitive electronics and documents and computer rooms.
Halotron II - Clean, used for sensitive electronics and documents and computer rooms.
FM 200 - Usually large tanks connected used used for sensitive electronics and documents, computer rooms and sometimes where explosions may occur..

Water Type - Cools burning material by absorbing heat from burning material. Effective on Class A fires, Water fire extinguishers 2.5 gallons (9 liters) of water in a tall, stainless steel cylinder. Water Mist uses a fine misting nozzle to break up a stream of deionized water.

Water - APW - Air Pressurized water used for Class A fires involve organic solids such as paper and wood
