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, the authors 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. They have found a set of non-flammable mixtures of the kind of AR+CO{sub 2}+Freon contained less than {approximately}8.4% of iso-C{sub 4}H{sub 10} for K{sub L}/muon counter of KEK B-factory at KEK.
