Basic Hazards Toxic Flammable Reactive Corrosive Compressed Gas |
|
Compressed Gases Compressed gases are unique in that they represent both a physical and a potential chemical hazard (depending on the particular gas). Gases contained in cylinders may be flammable, reactive, corrosive, or toxic. Because of their physical state (gaseous), concentrations in the laboratory air can increase instantaneously if leaks develop at the regulator or piping systems, creating the potential for a toxic chemical exposure or a fire/explosion hazard. Often there is little or no indication that leaks have occurred or are occurring. Systems must be leak tested at a minimum when changing out cylinders. The large amount of potential energy resulting from compression of the gas makes a compressed gas cylinder a potential rocket if the tank or valve is physically broken. Secure all cylinders during transport, storage and use.
