Abstract: At 1:30 p.m. on June 28, 2017, Employees #1 and #2 were working together from a scissor lift, approximately 20 feet in the air inside the Central Plant, attempting to replace a chlorine chemical tubing line that consisted of PVC conduit. Using a PVC pipe cutter, Employee #1 cut into a parallel, visibly similar PVC conduit pipe, assuming it was the blank chlorine line. Both pipes were unlabeled. However, the cut pipe began to leak sulfuric acid onto both employees. Employee #1 received third degree chemical burns on his right arm and second degree chemical burns on his neck, right side of face, and chest. Employee #2 sustained second degree chemical burns on his left arm and lower back, along with first degree burns on his right arm and face. Employee #1 and #2 were transported to a nearby hospital, where they were treated and released later that evening.
