What is the function of a green tag in the context of lineman operations?

The function of a green tag in the context of lineman operations is to indicate that grounding is applied. Grounding is a critical safety measure that helps prevent electrical shock hazards and ensures that the equipment is safely connected to the ground. When a green tag is in place, it signals to all personnel that grounding procedures are actively being followed, thereby alerting them that the equipment is in a safe state while repairs or maintenance are being conducted.

In contrast, other tags such as red or yellow often signify different statuses—such as equipment being out of service or that operations should not be performed—pointing out that the green tag's specific role is to assure safety through grounding.
