Latest company news about Is fm200 dangerous to humans?



• Non-Ozone Depleting

• Safe for Total Flooding of Occupied Spaces

• Clean — No Residue to Clean Up

• Non-Damaging to Hazard Contents

• Fast Acting

• Active Fire Suppression Agent

• UL Component Recognized

• FM Approved



FM-200 (1,1,1,2,3,3,3-heptafluoropropane) is a compound of carbon, fluorine and hydrogen (CF3CHFCF3). It is colorless, odorless and electrically non-conductive. It suppresses fire by a combination of chemical and physical mechanisms without affecting the available oxygen. This allows personnel to see and breathe, permitting them to leave the fire area safely. FM-200 has acceptable toxicity for use in occupied spaces when used as specified in the United States Environmental Protection Agency (EPA) Significant New Alternative Policy (SNAP) program rules. Although FM-200 is considered non-toxic to humans in concentrations necessary to extinguish most fires, certain safety considerations should be observed when applying and handling the agent. The discharge of FM-200 may create a hazard to personnel from the undecomposed agent itself and from the decomposition products which result when the agent is exposed to fire and other hot surfaces. Exposure to the agent is generally of less concern than is exposure to the decomposition products. Unnecessary exposure to the agent or the decomposition products should be avoided.


In tests, the acute toxicity of FM-200 was shown to be
equivalent to that of Halon 1301. FM-200 has been evaluated for cardiac sensitization through test protocols
approved by the US EPA. The EPA’s SNAP Program
classifies FM-200 as acceptable for use as a total flooding agent in occupied spaces. Refer to the SNAP program rules for more information.


FM-200 is clean, leaves no residue, thereby eliminating
costly after-fire clean-up, and keeping expensive “downtime” to a minimum. Most materials such as steel, stainless steel, aluminum, brass, and other metals as well as
plastics,rubber and electronic components are unaffected
by exposure to FM-200.

FM-200 agent complies with the NFPA Standard 2001:
Standard for Clean Agent Fire Extinguishing Systems,
EPA SNAP Program (Significant New Alternate Policy),

Underwriters Laboratories, Inc. (UL) and Factory Mutual
Research Corporation (FMRC).
USEFM-200 is used in total flooding fire suppression systems.
It is stored in steel containers, and is super-pressurized
with nitrogen to aid in expelling the agent. The discharge
time is 10 seconds or less. The maximum fill density of
the agent storage is 70 lb./ft.3.
