Compressed gases are quite common in most workplaces. Although most people assume that compressed gases refer to high pressure cylinders such as those used in welding, compressed gases also include pressurized aerosol cans (e.g., lubricating oils, electronics dusters).​

Gases may be pressurized, dissolved in solution, liquefied or refrigerated (cryogenic).  In addition to the obvious chemical hazards, there are also potential exposures to the mechanical hazards associated with gases including pressure and temperature.
