Gas piping at multiple meter installations must be marked with what?

• A. A plastic tag
• B. A stamped seal
• C. A metal tag
• D. A brass plate

Answer: (C)

Marking gas piping that serves more than one meter is about clearly identifying a shared-supply installation. The marking should be a durable metal tag attached to the piping so it's easy to read and remains legible under outdoor conditions and physical wear. Metal tags hold up against weather, corrosion, and abrasion better than plastic, and a stamped seal or a brass plate doesn’t provide the standardized, durable identification needed for this purpose. This ensures crews and the gas utility can quickly recognize that this section of piping serves multiple meters and handle it accordingly.
