Compressed gases are used throughout the College of Environmental Science and Forestry. Regardless of the use or content of the cylinder, compressed gas cylinders represent a serious health and safety hazard. An improperly handled cylinder may result in serious injury or death through the sudden release of its contents. A flammable gas suddenly released into an area may cause a fire and explosion. Toxic or reactive gas suddenly released into an area may cause asphyxiation. Even a “harmless” gas could create such high concentrations that it would be impossible to breathe. Also, a compressed gas cylinder is a potential projectile or bomb if not properly secured.
A. General Guidelines for Handling Compressed Gases
These guidelines must be followed for all compressed gas cylinders used at ESF.
B. Flammable Gases
Special care must be taken when flammable gases are used in confined spaces.
C. Attaching Regulators
D. Leak Testing
Cylinders and connections should be tested by SNOOPä or a soapy water solution. Test the cylinders before regulators are attached and again after the regulators or gauges are attached.
E. Empty Cylinders
F. Cryogenic Liquids
