In a recent Q&A on the FacilityCare website, consultant Brad Keyes answered a question about electrical outlets and oxygen cylinders.
Q: Is there a code or standard that restricts the distance between a storage rack of 6 E size cylinders and nearby electrical outlet receptacles?
A: No, there is not an NFPA code or standard that addresses how close a storage rack of oxygen cylinders may be stored to an electrical switch or outlet receptacle for spaces that have less than 3,000 cubic feet of compressed medical gases, which is typical for a nursing unit. However, NFPA 99 (both the 1999 edition and the 2005 edition) does require ignition sources (e.g., electrical switches, outlets, receptacles, thermostats, etc.) to be mounted 60 inches above the floor in rooms designated for the storage of 3,000 cubic feet or more of compressed medical gases.
