FM-200 provides superior fire protection in a wide range of applications from sensitive electrical equipment to industrial applications using flammable liquids.
FM-200 is ideal for applications where clean-up of other media presents a problem, where weight versus suppression potential is a factor, where an
electrically non-conductive medium is needed and where people compatibility is an overriding factor. When environmental impact is a consideration, FM-200
is particularly useful. It has zero ozone-depleting potential, low global warming potential and a short atmospheric lifetime. These characteristics make it suitable not only for new installations using total flooding systems, but also for Halon 1301 replacement applications.
FM-200 is an odorless, colorless, liquefied compressed gas.  It is stored as a liquid and dispensed into the hazard as a colorless, electrically nonconductive
vapor that is clear and does not obscure vision. It leaves no residue and has acceptable toxicity for use
in occupied spaces at design concentration. FM-200 extinguishes a fire by a combination of chemical and physical
mechanisms. FM-200 does not displace oxygen and therefore is safe for use in occupied spaces without fear of oxygen

FM-200 is manufactured to these specifications:
• Mole%: 99.0 Minimum
• Acidity, ppm by weight: 3.0 Maximum
• Water content, % by weight: 0.001 Maximum
• Non-volatile residues, gram/100mL: 0.05 Maximum
