Which term describes the labeling requirement for equipment that may be subject to arc-flash hazards?

Explanation:
The labeling requirement is described as a warning marking for electrical equipment. This label is worn on equipment that might have arc-flash hazards to alert workers about the danger and provide essential protective information (like incident energy, PPE required, and boundaries) before anyone works on it. NFPA 70E and related safety standards require these warning markings to communicate the arc-flash risk and help workers decide the appropriate precautions. The other terms refer to the hazard itself, the physical safeguarding of equipment, or electrical parameters used to assess risk, not the labeling mandate.
