Which statement correctly describes a labeling requirement for elevated piping?

• A. Every 10 feet, at all changes of direction, and on both sides of wall penetrations
• B. Every 20 feet
• C. Only at changes of direction
• D. Only near meters

Answer: (A)

Labeling elevated gas piping at regular intervals is essential so anyone can quickly identify the piping and its contents, no matter where they are standing. The rule to place labels every 10 feet, at every change of direction, and on both sides of wall penetrations ensures visibility from multiple angles and along the entire run, including around bends and where the pipe passes through walls. If you only labeled at changes of direction or only near meters, long unmarked stretches could cause confusion or delay in emergencies or maintenance. This spacing provides consistent, visible identification in typical building layouts and aligns with NFPA 54 labeling practices.
