Purging relies on the principle that a combustible (or flammable) gas is able to undergo combustion ...
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.
