NFPA 99, "Standards for Health Care Facilities," establishes labeling requirements for medical gas systems. Compliance with NFPA 99 is required for JCAHO certification.
NFPA 99 Section 5.1 requires that all pipes carrying medical gas must be permanently labeled with their contents, direction of flow, and pressure (if between 200 and 300 psi). The text of the label should run parallel to the pipe and must be at least 3/8" tall. The table above shows the standard colors and designations established by the code.
Labels must appear in the following locations:
Valves and cylinders. Valves on pipes containing medical gas or vacuum should carry tags bearing the inscription "(Name of gas) (source, main line, riser for, service) shut-off valve for (location). Do not open or close valve except in an emergency." Cylinders containing compressed gases must be labeled to indicate their contents.
Door labels. NFPA 99 specifies the text that is to appear on doors to enclosures containing medical gas components, depending on the type of gas. Door labels should read:
