What is the minimum arc rating of PPE required for Category 2?

The minimum arc rating of personal protective equipment (PPE) required for Category 2 is 8 Cal/cm². This category falls within the revised approach to assessing the hazards associated with arc flash incidents and is part of the classifications outlined in the National Fire Protection Association (NFPA) 70E standard for electrical safety in the workplace.

The 8 Cal/cm² rating is significant because it indicates the amount of thermal energy that a worker may be exposed to in the event of an arc flash, which can result in severe injuries if appropriate protective measures are not followed. The classification ensures that workers are equipped with suitable clothing and gear that can withstand potential arc flash energy levels, thus reducing the risk of burns and other injuries.

Ultimately, adherence to this standard is critical for ensuring that individuals working with electrical equipment are protected from the life-threatening hazards posed by electrical arcs. Using PPE with a minimum of 8 Cal/cm² arc rating combines safety with compliance to established electrical safety practices, making it an essential requirement in workplaces handling energized equipment.
