Which item on the red tag identifies the building number, location, or system number?

• A. Owner's name
• B. Address of building
• C. Printed name of service person
• D. Building number, location, or system number

Answer: (D)

The main idea here is that a red tag must clearly identify which exact system is being referenced at a site. The field that does this is the Building number, location, or system number. This identifier ties the tag to the precise property and system, which is crucial when multiple systems or buildings exist at one location or across a property portfolio.

Other fields serve related but different purposes: the owner’s name tells you who owns the property, the address shows where it is, and the printed name of the service person identifies who performed the work. None of these alone pin down which specific system or building the tag refers to, so the Building number, location, or system number is the best choice.
