Excerpt from ERG Guide 115 [Gases - Flammable (Including Refrigerated Liquids)]: DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED. CAUTION: Hydrogen (), Deuterium (), Hydrogen, refrigerated liquid and Hydrogen and Methane mixture, compressed will burn with an invisible flame.Use an alternate method of detection (thermal camera, broom . This paper reports the results of flammability studies for methane, propane, hydrogen, and deuterium gases in air conducted by the Pittsburgh Research Laboratory. Knowledge of the explosion hazards of these gases is important to the coal mining industry and to other industries that produce or use flammable gases. . Previous gas flammability .
Methane, often sold under the name natural gas, is used primarily as a residential and commercial heating fuel. Because methane is explosive when present in the air, leaks of natural gas are dangerous. In its natural state methane has no color or odor, so gas companies add an unpleasant sulfurous smell, making gas leaks easy to detect.
