The color coding for gas lines is intended to indicate utility type?

• A. To indicate paint color
• B. To indicate manufacturer
• C. To indicate load capacity
• D. To indicate the type of utility

Answer: (C)

Color coding is used to communicate what service a line carries, so workers can quickly identify the utility type and take the appropriate safety precautions. For gas lines, yellow is the standard mark, signaling natural gas or propane, which helps distinguish it from other utilities like water, electric, or sewer. This cue is about what the line provides, not about paint aesthetics, who manufactured it, or how much load it can carry. Recognizing the utility type informs the correct safety steps, such as digging restrictions, valve locations, and required notifications before any work.
