Full-scale fire suppression testing of HFC-227ea and HCFC Blend A was conducted in a 121 m3 compartment. HFC-227ea was tested at 7.6 and 8.8%; HCFC Blend A was tested at 8.6, 9.3, 10, 12 and 14% (by volume). Information on discharge characteristics and fire suppression performance of these halon replacement agents was obtained. HFC-227ea extinguished all test fires at the test concentrations. HCFC Blend A extinguished all test fires only at test concentrations of 12% or higher. These two agents produced halogenated acid gases whose quantity depended on the type, concentration and discharge of the agents and the size of the test fires.
