The effect of halon 1301 fire extinguishing agent on the response of combustible gas indicators

Affens, W.A.

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