How are the identification tags on Con Ed main valves structured?

The identification tags on Con Ed main valves are structured with the ID numbers located inside the valve cover. This design choice ensures that the identification numbers are protected from environmental factors and potential damage. By placing the tags inside the cover, it allows for better durability and legibility, which is essential for maintenance and emergency response. The placement also helps to prevent tampering or loss of the identification information, making it critical for the safe operation and management of the utility infrastructure.

The other answer choices reflect scenarios that do not accurately describe the system used by Con Ed. For example, stating that there are no tags present on valves would overlook the importance of identification for utility operations. Suggesting that ID numbers are outside the valve cover would not protect the tags adequately, and noting that the ID numbers are not standardized would misrepresent the systematic approach to utility identification that is generally employed for consistency and reliability in maintenance and operational procedures.
