Is HFC 227 the FM-200?
HFC-227 ea is known chemically as Heptafluoropropane. FM200 is a colourless gas which is liquified under pressure for storage.
Is heptafluoropropane harmful to humans?
It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation. Get medical attention if adverse health effects persist or are severe. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway.
How does HFC 227 work?
HFC-227ea literally removes heat energy from the fire to the extent that the combustion reaction cannot sustain itself. Additionally, there is a chemical extinguishing action contributed by HFC-227ea. Trace amounts of free radicals are released in a fire, ultimately inhibiting the chain reaction of combustion.
What gas is used in FM-200?
FM-200™ is a colorless, compressed liquefied gas used to extinguish fires and is a popular replacement for Halon fire suppression systems. FM-200™ fire suppression systems are pressurized with nitrogen, waterless, and upon activation, FM-200™ discharges as a gas to suppress the fire.
What is the full form of FM-200?
FM200 is the commercial name given to it by its makers, DuPont. Its technical name is ‘heptafluoropropane’ and it is a colourless, odourless halocarbon.
What is FM-200 made of?
FM-200™, also known as HFC-227ea or a heptafluoropropane, is a compound made up of carbon, fluorine, and hydrogen (CF3CHFCF3) and is produced by Chemours. It can be used in a wide variety of applications to provide fast-acting fire suppression.
What is heptafluoropropane used for?
Use. HFC-227ea is used in fire suppression systems that protect data processing and telecommunication facilities, and in fire suppression of many flammable liquids and gases. HFC-227ea is categorized as a Clean Agent and is governed by NFPA 2001 – Standard for Clean Agent Fire Extinguishing Systems.
Is FM-200 gas toxic?
IsFM-200™ safe to breathe? Clean agent systems using FM-200™ are non-toxic to humans in levels used for extinguishing fires. When designing a fire suppression system, particular emphasis is placed on accurately calculating clean agent concentration levels to be safe in occupied spaces.
What is Heptafluoropropane used for?
What is HFC clean agent?
Hydrofluorocarbon (HFC) clean agent is a chemical compound that suppresses Classes A, B and C fires without water or harmful chemical residue. In 1994, HFC clean agents largely replaced chlorofluorocarbon (CFC) halon agents, which cause ozone damage.
Which gas is used for fire?
Carbon dioxide is primarily suitable for fighting fire classes B and C. Due to its physical properties, carbon dioxide is the only extinguishing gas that is also used in fire extinguishers and fire extinguishing devices.
What is the difference between FM-200 and CO2?
Not to be confused with a CO2 System, FM 200 fire suppression systems are electrically non conductive and safe for humans. FM 200 systems reach an extinguishing level within 10 seconds, making it one of the fastest and most effective means of stopping fires before they can cause significant damage.
What is heptafluoropropane?
1,1,1,2,3,3,3-Heptafluoropropane, also called heptafluoropropane, FM200, HFC-227 or HFC-227ea (ISO name), as well as apaflurane (INN), is a colourless, odourless gaseous halocarbon commonly used as a gaseous fire suppression agent.
What is the concentration of HFC-227ea for effective fire suppression?
Effective fire suppression requires introducing a concentration of the HFC-227ea agent between 6.25% and 9% depending on the hazard being suppressed. Its NOAEL for cardiac sensitization is 9%.
What is the Henry’s Law constant for 1-1 1 2-3-heptafluoropropane?
On-line posting date: 17 Aug 2012 The Henry’s Law constant for 1,1,1,2,3,3,3-heptafluoropropane is estimated as 16 atm-cu m/mole (SRC) using a fragment constant estimation method (1). This Henry’s Law constant indicates that 1,1,1,2,3,3,3-heptafluoropropane is expected to volatilize rapidly from water surfaces (2).
Is there a natural source of 1-1-1 2-3-heptafluoropropane?
Use data indicate that the general population may be exposed to 1,1,1,2,3,3,3-heptafluoropropane primarily via inhalation when using pharmaceutical aerosols and metered-dose inhalers that contain 1,1,1,2,3,3,3-heptafluoropropane. (SRC) There is no natural source for 1,1,1,2,3,3,3-heptafluoropropane (1).
