Abstract
A combustible gas indicator (CGI) was tested in combustible vapor-air mixtures with and without the presence of Halon 1301 vapors. GCI response to hydrocarbon vapors was reduced on the average of about 30 percent in the presence of Halon 1301 vapors at fire extinguishment concentrations for hydrocarbon-type fire (3.7 percent) and about 45 percent at inerting concentrations (7.4 percent). Some filament deterioration was noted in filaments which were exposed to Halon vapors. Sensitivity loss for these filaments averaged about 9 percent.
