A few years ago I received a phone call from an OSHA inspector asking for one of our training manuals. He sounded upset and demanded that it be sent overnight. A worker had died in an electrical arc flash only a few weeks after attending one of our training classes. At first, I wondered if we had some type of major error in our training manuals or that I had missed teaching this employee something critical, which resulted in getting him killed. I told him that it would be absolutely no problem for me to have the training manual delivered to him overnight.
After a few days of waiting, I was starting to get worried. I hadn’t heard anything back on the incident. I decided to give the OSHA Official a quick call (he had given me his cell when I was forthright in agreeing to help), and I quickly discovered that an employee died because of his night supervisor. It turns out that several employees were told by their supervisor to fix an issue that was clearly a hazard. This was during Hurricane Gilbert and in a driving rain, lightening had struck a transformer and “fried” it. The power was off, and the transformer was visibly bulging and smoking. The group of employees tried informing their supervisor that what he was asking of them would violate the training they had received just a few days earlier. The supervisor didn’t care. He didn’t want HIS supervisors coming in the next day to give him a hard time for not fixing the problem. He demanded that the Low Voltage qualified employees open a medium voltage piece of equipment.
As it turns out – that particular night the driving rain made opening the cabinet even more hazardous. One of the employees that night had worked on medium voltage for another company in the past, and was pushed by his supervisor to go ahead and address the issue. Despite his prior experience, he wasn’t qualified to do the job, and the conditions were nothing he had ever experienced. The employee brought the supervisor along with him to point out that there was nothing that he could do to the equipment As he reached out with his screwdriver he used to open the cabinet to show his supervisor the problem, the equipment arced to his body (probably due to a continuous stream of water) and killed him. The supervisor caught his employee’s body as he fell back, lifeless. It’s the last call that anyone wants to get.
We had informed the company in our proposal that electrical supervisors should attend the full training or a special supervisory course, but the supervisors indicated they were too busy. Electrical Safety & Arc Flash Training for supervisors not only improves the safety of themselves, but for the lives of the people that they are in charge of. If this man’s supervisor had the proper training he would have known that he was putting the lives of his workers in danger. Safety never ends. Remember, you are responsible for your safety.
Type of training. The training required by this section shall be of the classroom or on-the-job type. The degree of training provided shall be determined by the risk to the employee.
