La description

 1) As the first non ozone-depleting alternative for Halon ***1, HFC***7ea (Heptafluoropropane) is used in fire suppression systems in data-processing and telecommunication facilities. Effective fire suppression requires introducing a concentration of the HFC***7ea agent between 6.*5% and 9% depending on the hazard being protected. Its NOAEL level for cardiac sensitization is 9%. The US EPA allows concentration of 9% volume in occupied spaces without mandated egress time, or up to *0.5% for a limited time. Most fire suppression systems are designed to provide concentration of 6.***9%.
In addition, HFC***7ea leaves no residue on valuable equipment after discharge. HFC***7ea contains no chlorine or bromine atoms, presenting no ozone depletion effect, but its global warming potential is high. Its atmospheric lifetime is approximated between *1 and *2 years.
2)HFC***7ea is used as an aerosol propellant in pharmaceutical metered dose inhalers such as those used for dispensing asthma medication.
