Compressed gases may present both physical and health hazards. Gases may be flammable, reactive, corrosive or toxic and these properties must be considered when developing experimental procedures and designing apparatus. In addition, compressed gases, when not handled properly or not contained in properly designed vessels, can be extremely hazardous with a high potential for explosion. Although each approved gas cylinder is designed, constructed, and tested to safely contain its contents, the procedures listed below should be taken in handling and storing of compressed gases*.

*Work with particularly hazardous gases with special procedures and in approved gas storage cabinets. Researchers must contact EH&S (644-7682 or 644-8916) before working with highly toxic (eg arsine, diborane, methyl bromide, nitric oxide, nitrogen dioxide, phosgene, phosphine), extremely flammable, reactive or pyrophoric gases (eg. Silane, phosphine). Gases with these properties require adherence to special building and fire codes.
