What does the color orange signify in utility marking?

Water lines
Gas lines
Communications, phone lines
Electric lines

The correct answer is: Communications, phone lines

In utility marking, the color orange specifically signifies the presence of communications, such as phone lines. This regulatory color-coding system is used to help prevent accidents during excavation or construction work. Each color corresponds to a different type of utility, allowing workers to quickly identify and manage potential hazards before they begin digging. Understanding these color codes is critical for safety and to avoid disrupting important services. For instance, striking a communications line during construction could disrupt phone or internet service, which is significant for both residential and business customers. The accuracy in identifying these lines helps in planning and executing construction projects without unintended consequences. The other options represent different utilities: water lines are usually marked in blue, gas lines are often indicated by yellow, and electric lines are marked in red. Each color is designated to provide clear communication about the type of utilities present underground, emphasizing the importance of adhering to these color codes for the safety and efficiency of construction practices.
