Where must the service tag be attached after service?

• A. Attached to the respective riser of each system.
• B. Attached to the service panel.
• C. Attached to the main entrance.
• D. Attached to the equipment rack.

Answer: (A)

Service tags are meant to stay with the specific equipment that was serviced so everyone can see that unit has been touched and by whom. Attaching the tag to the respective riser of each system keeps the tag with that exact system’s vertical pathway, making the indication clear and persistent as work orders or personnel move around. If the tag were placed on a service panel, main entrance, or a separate rack, it could become detached or fail to identify the correct system, leading to confusion or unsafe re-energizing of the wrong equipment.
