Under what conditions is a CAUTION tag installed at equipment control stations in preparation for performing maintenance or repairs?

Correct Answer: Option D — When operation of the equipment requires temporary special instructions to be provided.

CAUTION tags are used to provide specific operational instructions or warnings for equipment that may be operated under restricted conditions. Unlike DANGER tags, which prohibit operation entirely, CAUTION tags alert personnel to potential hazards or special procedures required to operate the equipment safely without causing damage or injury.
