Abstract: At 8:30 a.m. on August 1, 2020, Employees #1, #2, and #3, employed by a electric al services company in the telecommunications field, were working on a multi-emp loyer construction project at the intersection of two streets. They were pothol ing to locate underground utility lines, with the aim to then bore in a new fibe r optic line under the intersection. After finding what they thought was over-p our from the concrete curb, they used a Ring-o-matic Vacuum Excavator to excavat e over top of the concrete. They then used a jackhammer on the concrete. The j ackhammer bit made contact with a 12,470-volt underground electrical distributio n line, and an electric arc explosion occurred. Employees #1 and #2 were killed by electrocution. Employee #3, who was knocked down by the force of the explos ion, was transported to the hospital, where he was observed, determined to have no injuries, and released.
