We present the design and the test results for a real-sized prototype resistive plate chamber by using cosmic-ray muons for the forward region of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC). In particular, we investigate the effects of adding SF 6 to the gas mixture for the avalanche mode operation of a resistive plate chamber. A small fraction of SF 6 is very effective in suppressing streamer signals in a resistive plate chamber. The shapes of the muon detection efficiency and the muon cluster size remain similar, but are shifted to higher operating voltage by SF 6. The noise cluster rate and size are not influenced by SF 6.
