HFC-227EA is a colourless, odourless gaseous halocarbon commonly used as a gaseous fire suppression agent. HFC-227EA finds use in fire suppression systems in data processing and telecommunication facilities, and in protection of many flammable liquids and gases. HFC-227EA falls in the category of Clean Agents and is governed by NFPA 2001 – Standard for Clean Agent Fire Extinguishing Systems. Effective fire suppression requires introducing a concentration of the HFC-227EA agent between 6.25% and 9% depending on the hazard being protected.

HFC-227EA contains no chlorine or bromine atoms, presenting no ozone depletion effect. Its atmospheric lifetime is approximated between 31 and 42 years. It leaves no residue or oily deposits and can be removed by ventilation of the affected space.

As an aerosol propellant, HFC-227EA is used in pharmaceutical metered dose inhalers such as those used for dispensing asthma medication.
