Clean fire extinguishing agents mainly include heptafluoropropane(HFC 227ea) fire extinguishing agents, perfluorohexanone(also known as FK 5 1 12)and carbon dioxide fire extinguishers. These fire extinguishing agents are colorless, odorless, non-corrosive, non-conductive, and have no destructive effect on the atmospheric ozone layer. They effectively extinguish fires through chemical inhibition and cooling, and will not cause pollution to the environment, meeting environmental protection requirements.
Heptafluoropropane, also known as HFC 227ea, FM200. It is a clean gas fire extinguishing agent that meets the requirements of the NFPA-2001 specification formulated by the National Fire Protection Association (NFPA). HFC 227ea gas's characteristics are "non-conductive, highly volatile gaseous fire extinguishing agent, leaving no residue during use". At the same time, heptafluoropropane clean fire extinguishing agent is harmless to the environment, has a short retention period in nature, has high fire extinguishing efficiency, and is non-toxic and non-toxic at a certain design concentration. FM200 is suitable for protected areas where staff are stationed. After testing by the National Testing Center in December 1996, it and carbon dioxide are both major products that replace halogenated hydrocarbons.

Perfluorohexanone,also know as FK 5 1 12,FK-5-1-12, it is a colorless, electrically non-conductive fluid chemical known as fluoketone, FK 5 1 12 is long-term sustainable technology with zero ozone depletion, extremely low global warming potential, and short atmospheric lifetime. FK 5 1 12 offers a unique combination of safety, low environmental impact and exinguishing performance.

Carbon dioxide fire extinguishers also called CO2 fire extinguishers which are highly effective against B & C fire classes. They are a good solution for tackling fires involving:
Computer equipment
Electrical appliances
Flammable liquids such as petrol, diesel, paraffin & paint
A CO2 extinguisher should NOT be used for fires involving:
Wood
Paper
Textiles
Fat (such as deep fat fryers and chip pans)
Cooking oils
Amoung them, Perfluorohexanone is the most perfect halon substitute at present. Its excellent fire extinguishing performance and environmental friendliness determine its wide application prospects in many important places,
