Ownership signs at utility sites must include which of the following?

The correct answer emphasizes the importance of providing vital information that is critical for safety and emergency response at utility sites. Ownership signs at utility sites are designed to convey essential details to the public and emergency responders. Including the utility name allows individuals to easily identify which company is responsible for the service, while the emergency phone number is crucial for prompt assistance in case of incidents or emergencies. This information enables quick communication with the utility for both routine inquiries and urgent situations.

The other options, while containing relevant information, do not specifically address the immediate needs for identification and emergency contact that are crucial in utility contexts. Construction dates, inspection details, or maintenance schedules do not provide immediate, actionable information for contact or crisis management, which is why they are not included as essential elements on ownership signs.
