It sounds like he was wearing insulating gloves with leather protectors and using an arc flash face shield, but no balaclava or arc flash suit. It's so sad he was injured when an arc flash suit and hood matching the potential incident energy could have prevented it. That's why NFPA 70E and OSHA training play a crucial role in developing a safe workforce. Prayers for quick healing and no permanent disability.

    So true Debra. Matching to the hazard is critical. Glad they got partly right. That saves lives but burns aren't fun even if they are limited. Hugh

Any more info about this? What was the voltage, panel type,......? What exactly was he doing when the flash occurred?

    We don't have any more info than the news. When we do investigations we can't share anything but what is public. In this case, we have not been involved. I'd bet it was 3P system. Rarely see arc flash hurting anyone below 300V (208V 3P is an exception). Hugh

What was so critical in a window factory, that the panel could not be put in an electrically safe work condition? Perhaps the company can explain the necessity to complete the work energized. I was burnt in a 120/208 3 phase panel from an arc, so it does happen

    Anything 3-phase can ignite clothing so it is important to study.

By any chance would you be able to post pictures of the area where it happened and the body parts if possible
