Compressed Gas

Lab directors (faculty/lab managers/supervisors) must obtain pre-approval from Environment, Health & Safety (EHS) to purchase restricted hazardous compressed gases that may require special precautions or engineering controls, or create additional hazards during an emergency response.

The following hazardous gasses, in cylinder sizes larger than a lecture bottle (size LB), are included in this policy:  carbon monoxide, flammable gasses (e.g. hydrogen >5%), corrosive gasses (e.g. ammonia), oxidizing gasses (e.g. liquid oxygen, oxygen >25%,  nitrous oxide, chlorine, fluorine), pyrophoric gasses (e.g. arsine, disilane, diborane, germane, phosphine, silane), and toxic and highly toxic gasses per NFPA 55.

For more information about this requirement, refer to the Policy information located on the Restricted Hazardous Gas Approval Form below.
