Compressed gases

Publisher Summary Compressed gases are more dangerous than chemicals in liquid or solid form because of the potential source of high energy, low boiling-point of some liquid contents resulting in the potential for flashing, ease of diffusion of escaping gas, low flashpoint of some highly flammable liquids, and the absence of visual and/or odor detection of some leaking materials. Compressed gases present a unique hazard from their potential physical and chemical dangers. Unless cylinders are secured, they may topple over, cause injury to operators, or become damaged themselves and cause contents to leak. If the regulator shears off, the cylinder may rocket like a projectile, or torpedo, dangerously around the workplace. Other physical hazards stem from the high pressure of a cylinder's contents, for example, accidental exposure of a compressed gas/air hose or jet to eyes or to an open cut or wound, whereby the gas can enter the tissue or bloodstream, is particularly dangerous.
