The RPC (resistive plate counter) has good time and position resolution. These factors make it an attractive candidate for trigger system at collider experiment. The standard gas mixtures (Ar+iso-C/sub 4/H/sub 10/+Freon) used in RPC are very flammable when leaked into air. In view of safety issue,we have studied non-flammable gas of Ar+CO/sub 2/+iso-C/sub 4/H/sub 10/+Freon as a function of ratio Ar:CO/sub 2/ allowed in non-flammable gas mixtures for the RPC with ABS electrodes. The basic performance of the various mixtures have been measured; singles (untriggered) count rate, detection efficiency and charge spectra versus operating voltage. We have found a set of non-flammable mixtures of the kind of Ar+CO/sub 2/+Freon contained less than /spl sim/8.4% of iso-C/sub 4/H/sub 10/ for K/sub L//muon counter of KEK B-factory at KEK.
