Arc Flash Labels and Signs

Arc flash labels are warning labels that are affixed to electrical equipment to warn workers of the potential for an arc flash hazard. Arc flash is a sudden and violent release of electrical energy that can occur when a fault or short circuit causes current to flow through the air between conductors or to ground.

Arc flash labels provide important information about the equipment, the potential arc flash hazard, and the personal protective equipment (PPE) that should be worn when working on or near the equipment. The label typically includes the following information:

Equipment rating: This is the voltage, amperage, and other specifications for the electrical equipment.

Incident energy: This is the amount of thermal energy that could be released in the event of an arc flash.

Flash protection boundary: This is the minimum distance from the electrical equipment that a worker must maintain to avoid serious injury in the event of an arc flash.

Required PPE: This includes the types of PPE that workers must wear to protect themselves from the potential hazards of an arc flash, such as arc-rated clothing, gloves, and face shields.

Arc flash labels are an important part of electrical safety in industrial and commercial settings. They help to ensure that workers are aware of the potential hazards associated with electrical equipment and take appropriate precautions to protect themselves.
