Methane

Formula                  : CH4
Physical Properties  : Form : colourless, odourless gas 
                                 Melting point : -182 C 
                                 Boiling point : -164 C 
                                 Water solubility : slight 
                                 Density : 0.717 g/l at 20 C 
                                 Explosion limits : 5 - 15%
Principal Hazards   : Methane is very flammable. Mixtures of methane with air are explosive within 
                                  the range 5-15% by volume of methane. 
                                 Methane can react violently or explosively with strong oxidizing agents, such as 
                                   oxygen, halogens or interhalogen compounds. 
                                 At high concentration methane acts as an asphyxiant.
Toxicological Properties :
            *  Methane is inactive biologically and essentially nontoxic; therefore, the majority is the
                   exclusion of an adequate supply of oxygen to the lungs.
            *  Methane is not listed in the IARC, NTP or by OSHA as a carcinogen or potential
                    carcinogen.
Reactivity Data       : Stability : Stable
                                Incompatibility (Materials to Avoid) : Oxidizers
                                Hazardous Decomposition Products : None
                                Hazardous Polymerization : Will not occur
                                Conditions to Avoid : None
