IEEE Electrical Safety Workshop Topics
Did you know that even though the accident rate within a mine is typically is 3 to 7 times greater than that of an industrial facility, some safety standards in a mine environment are less stringent than in the safer industrial facility? One example is that arc flash studies are not required in a mine.
While in the US OSHA recognizes NFPA 70E as an industry standard and 70E calls for mandatory arc flash studies, OSHA does not have jurisdiction in the mining industry. The US Federal Mine Safety and Health Act of 1977 established the Mine Safety and Health Administration (MSHA) as being responsible for enforcing electrical safety in mining operations, but MSHA does not require arc flash studies. Many mining companies, however, have recognized this oversight, and have taken preemptive steps to conduct their own arc flash studies to correct this oversight. Eaton presented a paper at the IEEE Electrical Safety Workshop that provides more detail.
