Hugh Hoagland has an article in Occupational Health & Safety magazine that discusses why meeting OSHA and NFPA requirements for PPE does not always provide adequate protection. The article defines the problem with this example:
"I received a call recently from a large electric utility. A line worker, we'll call him Bill, had been badly burned while performing work near a 69kV piece of equipment."
"The worker was in a 50 cal/cm2 rated winter suit. The undergarments and outer garments were provided by the company, but workers were given a lot of latitude on undergarments as long as the outer shell was compliant with the company's clothing policy."
"The worker chose not to wear an arc-rated sweatshirt even though this was commonly available in the company's clothing catalog. Instead, the worker was wearing a non flame-resistant T-shirt under the sweatshirt. Though this system was in compliance with NFPA 70E, NESC, and OSHA 1910.269, it was not the best choice for the worker."
