Product Information
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.
