We have operated successfully glass resistive plate counters in the streamer mode at the BELLE experiment by using a nonflammable gas mixture of argon 30%, butane-silver 8%, and freon, HFC-134a 62%. This freon is non-ozone-depleting but has a high global warming potential (1300 times higher than that of CO2). Thus freon gases might be unusable in the near future. We tested the performance of a glass resistive plate counter operated in the streamer mode with an alternative gas mixtures of argon, butane, CO2, and/or O2 gases and found an efficiency of about 90%.
