Chemistry Its chemical formula is CF3-CHF-CF3, or C3HF7. With a boiling point of −16.4 °C, it is a gas at room temperature. It is slightly soluble in water (260 mg/L). 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. 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%. The United States Environmental Protection Agency allows concentration of 9% volume in occupied spaces without mandated egress time, or up to 10.5% for a limited time. Most fire suppression systems are designed to provide concentration of 6.25-9%. The HFC-227ea fire suppression agent was the first non-ozone-depleting replacement for Halon 1301.Bleicher Harvey L Fischer Debra L Hermes Cynthia D Bradley Team Wins EPA Award for Halon Replacement Program Army AL&T July–August 2000 4 49–50 https://books.google.com/books?id=lc5LAQAAMAAJ&dq=halon+replacement+program&pg=RA2-PA50 18 November 2025 Acquisition Career Management Office Fort Belvoir, Virginia en 0892-8657 Google Books In addition, HFC-227ea leaves no residue on valuable equipment after discharge.http://fire-chief.com/fe227.asp Fike FE-227 Product Page 2006-12-12 https://web.archive.org/web/20071009070947/http://fire-chief.com/fe227.asp 2007-10-09 dead 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. Safety At high temperatures, heptafluoropropane will decompose and produce a small quantity of hydrogen fluoride. Other decomposition products include carbonyl fluoride, carbon monoxide and carbon dioxide. Explosive damage to heptafluoropropane-containing fire suppression systems in military vehicles, resulting in the production of hydrogen fluoride, has been reported in the medical literature to cause severe injury and death among exposed individuals.Zierold Dustin Chauviere Matthew Hydrogen Fluoride Inhalation Injury Because of a Fire Suppression System Military Medicine January 2012 177 1 108–112 10.7205/MILMED-D-11-00165 Prior to re-entry of a room where HFC-227ea system has been activated to suppress a fire, the atmosphere should be tested. An Acid Scavenging Additive added to heptafluoropropane reduces the amount of hydrogen fluoride. Contact with liquid HFC-227ea may cause frostbite. Climate change considerations Heptafluoropropane (HFC-227ea) contributes to climate change. It has a global warming potential (GWP) of 3,220 over 100 years.GOV.UK: Calculate the carbon dioxide equivalent quantity of an F gas. Retrieved on 2018-01-25. Due to its high GWP, the HFC-227ea has been included in the list of controlled substances of the Montreal Protocol (2016 Kigali Amendment, in effect in January 2019).Montreal Protocol Section 1.1. including 2016 Kigali amendment. Under EU regulations, production, imports and sales of HFC-227ea in spray cans such as freeze sprays or dusters have been prohibited since 2014, as the GWP is over the limit of 150 for these applications.Regulation (EU) No 517/2014 of the European Parliament and of the Council of 16 April 2014 on fluorinated greenhouse gases and repealing Regulation (EC) No 842/2006 — European Environment Agency https://www.eea.europa.eu/policy-documents/regulation-eu-no-517-2014 2021-03-11 www.eea.europa.eu en2016-11-23 EU legislation to control F-gases https://ec.europa.eu/clima/policies/f-gas/legislation_en 2021-03-11 Climate Action - European Commission en2020-08-31 ILT onderschept illegale spuitbussen in Rotterdamse haven - Nieuwsbericht - Inspectie Leefomgeving en Transport (ILT) https://www.ilent.nl/actueel/nieuws/2020/08/31/ilt-onderschept-illegale-spuitbussen-in-rotterdamse-haven 2021-03-11 www.ilent.nl Ministry of Infrastructure and Water Management nl Tradenames for HFC-227ea used as fire suppression agent FE-227 FM-200 (Dupont) (United States Environmental Protection Agency (EPA) SNAP Listed)https://www.epa.gov/snap/substitutes-total-flooding-agents Substitutes in Total Flooding Agents 3 May 2019 United States Environmental Protection Agency 20 November 2014 United States government FITECH - 227 (Fitech Engineers) Solkaflam 227 (Solvay Fluor) MH-227 (Shanghai Waysmos) (United States Environmental Protection Agency (EPA) SNAP Listed) Orient 227 (Orient Corporation) (United States Environmental Protection Agency (EPA) SNAP Listed) SR-200 (SRI) NAF S 227(Safety High Tech) Gallery See also Other fire suppression agents: Argonite ECARO-25 FE-13 FK-5-1-12 FS49C2 Halon 1211 Halon 1301 HFC-125 References Sinerji Fire Protection Product Page (Archived 2009-04-25) External links MSDS for heptafluoropropane MSDS for heptafluoropropane https://web.archive.org/web/20110822160434/http://msds.dupont.com/msds/pdfs/EN/PEN_09004a2f8009ef77.pdf 2011-08-22 MSDS for heptafluoropropane SDS for (LUKE 227) heptafluoropropane https://web.archive.org/web/20250603044443/https://www.lukealexandrea.com/wp-content/uploads/ebook/luke-227-sds.pdf 2025-06-03 SDS for Chemori 227 Category:Fluoroalkanes Category:Fire suppression agents Category:Aerosol propellants Category:Refrigerants Category:Hydrofluorocarbons
