FM200® (HFC 227ea) is known chemically as Heptafluoropropane and is manufactured by Dupont.  FM200® is a colourless gas which is liquified under pressure for storage. Like Halon 1301 it has a low toxicity level and is super pressurised with Nitrogen. It rapidly extinguishes most common types of fire through a combination of chemical and physical mechanisms.

FM200® contains no bromine or chlorine and therefore has zero Ozone Depleting Potential (ODP).

The atmospheric lifetime of FM200® is between 31 and 42 years.

FM200® has been found to be less toxic than Halon 1301, which makes it safe for use in the fully automatic mode in occupied areas.

Typically FM200® requires a design concentration of 7.9%, which is well below the 9% No Observable Adverse Effect Level (NOAEL) on cardiac sensitisation.
