OSHA’s current NFPA 70E and Electrical Safe Work Practices presentation states that the cost of arc flash burn injuries to the employer is now between 1 and 3 million dollars per incident, with a few exceeding 6 million dollars.
This is from this white paper. I have seen other documents that state the cost can easily exceed ten million dollars for a single incident. Don
In statistics presented at the 3rd International Conference on Electrical Injury in 1998, the Electric Power Research Institute estimated the direct costs of an electrical fatality at $1.3 million dollars, with total direct and indirect costs reaching between four and ten million dollars. Serious electrical injuries can be even more devastating to the people involved as well as to the bottom line. Floyd estimated the total of direct and indirect costs of a major electrical accident at $17.4 million in 2003 dollars.
