Pipe labels shall be located at a maximum interval of how many feet?

• A. 10 ft
• B. 15 ft
• C. 25 ft
• D. 20 ft

Answer: (D)

Labels on medical gas piping are placed so that identification is always accessible and you never have to search far to confirm what a line carries. Because staff trace lines through corridors, rooms, and behind panels, the labeling must be frequent enough that no portion of pipe goes more than 20 feet without a label. This 20-foot maximum balances practicality with safety: labeling more often would add workload without adding much safety benefit, while spacing labels farther apart could leave untagged sections and raise the risk of misidentification during normal work or emergencies. Labels are typically placed on accessible pipe sections at use points, where lines change direction, and near valves or connections to keep identification visible as people move through the facility.
