R227ea (commonly known as FM-200) is a widely used clean agent fire suppressant.
General Characteristics
- Chemical Name: 1,1,1,2,3,3,3-Heptafluoropropane ( CF3CHFCF3)).
- Physical State: Colorless, odorless, and electrically non-conductive gas.
- Extinguishing Method: It works through a combination of heat absorption (thermal cooling) and the chemical inhibition of the combustion process.
- Safety Profile: It is safe for use in occupied spaces (within specified concentration limits) and leaves no residue, meaning no cleanup is required after discharge.
- Environmental Impact:
- ODP (Ozone Depletion Potential): 0.
- GWP (Global Warming Potential): ~3220 (High, subject to F-Gas regulations).
