• A. Weather patterns
• B. Pipe accessories such as valves, insulating fittings, regulators, and corrosion control devices
• C. Customer addresses
• D. Land ownership

Answer: (B)

Symbols on utility maps and markouts indicate pipe accessories along buried lines—things like valves, insulating fittings, regulators, and corrosion control devices. This labeling helps crews quickly understand what components are present, where they’re located, and how they affect operation and safety during excavation or maintenance. Legends explain each symbol so workers know exactly what to look for on the ground. Other options don’t fit because weather patterns, customer addresses, or land ownership aren’t describing the physical components of the piping system.
