Abstract: At 10:15 a.m. on February 14, 2019, Employees #1, #2, and #3, employed by an electrical contractor, were engaged in electrical work at a dairy processing plant as part of a multiemployer construction project. They were installing a new breaker and wiring for a new air compressor. While pulling wires into a switch gear, a divider panel was pushed into an energized busbar, resulting in an electric arc blast. Emergency services transported the employees to the hospital, where they were treated for second and third degree burns to their heads, arms, shoulders, and hands. Employees #1 and #2 required hospitalization. Employee #3 was treated and released.
