Question

what special type of clothing are workers required to wear when performing energized tasks on high - power equipment, such as motor - control centers and switchgear? long - sleeve cotton work shirt arc - rated clothing flame - resistant clothing limited flammability clothing

Explanation:

When working on energized high - power equipment like motor - control centers and switchgear, the risk of arc flashes is high. Arc - rated clothing is specifically designed to protect workers from the hazards associated with arc flashes, including the intense heat and energy released during an arc event. Long - sleeve cotton work shirts don't provide sufficient protection against arc - related hazards. Flame - resistant clothing is more general, and arc - rated clothing is a more specific and appropriate choice for arc - flash hazards in this context. Limited flammability clothing also doesn't offer the level of protection needed for arc - flash situations.

Answer:

B. Arc - rated clothing
