29 CFR 1910.146(g)(2)(iii): The employer did not provide training to each affected employee whenever there was a change in permit space operations that presented a hazard about which an employee had not previously been trained: (a) ABB Inc. at 15001 County Road 46, Gilcrest, CO: On 7/25/2019, the employer did not provide training to each affected employee whenever there was a change in permit space operations that presented a hazard about which an employee had not previously been trained. Three employees were tasked with disassembling a three phase VonRoll transformer. One employee broke the plane of the transformer with a Cordless DeWalt impact wrench in his hand to attempt to disconnect the leads from the bushings. The atmosphere inside of the transformer ignited. The transformer was a permit required confined space. This condition exposed three employees to a fire and explosion hazard.
