Arc Flash Hazard Analysis An arc flash study (sometimes called an arc flash analysis or a hazard analysis) is an on-site study of your facility, conducted by a trained expert qualified to evaluate your electrical system and note areas that could present a risk to your personnel or equipment. The study will produce a report containing suggestions and instructions to keep your workers safe and to improve and maintain your electrical system. The report will recommend appropriate personal protective equipment (PPE) for your workers, and suggest adjustments you can make to reduce your workers’ exposure to arc flash hazards
