Hazardous Gases Program: In order to provide a safe U-M research environment, EHS has instituted a program with U-M Procurement Services which requires approval for specific hazardous gas purchases. Approval must be obtained to purchase the following gases in cylinders larger than a lecture bottle: carbon monoxide, chlorine, fluorine, hydrides (arsine, disilane, diborane, germane, phosphine, and silane), hydrogen, and toxic (NFPA health rating of 3 or 4). Oxygen over 25% also requires approval. Beyond this approval process, all hazardous gases must be used in compliance with NFPA 45 and NFPA 55. Under no circumstance should a researcher purchase more than a 1 year supply of any gas.
