    Description
    Methane is a colorless odorless gas. It is also known as marsh gas or methyl hydride. It is easily ignited. The vapors are lighter than air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is used in making other chemicals and as a constituent of the fuel, natural gas.;Methane is a colorless odorless gas. It is also known as marsh gas or methyl hydride. It is easily ignited. The vapors are lighter than air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is used in making other chemicals and as a constituent of the fuel, natural gas.;Methane, refrigerated liquid (cryogenic liquid) is a colorless odorless liquid. Flammable. Water insoluble.;Natural gas, refrigerated liquid (cryogenic liquid) appears as a flammable liquefied gaseous mixture of straight chain hydrocarbons, predominately methane.;Natural gas, [compressed] appears as a flammable gaseous mixture of straight chain hydrocarbons, predominately compressed methane.;GasVapor; Liquid;Liquid;COLOURLESS ODOURLESS COMPRESSED OR LIQUEFIED GAS.
