Abstract: Employee #1 was engaged in applying a viscous rubberized protective coating to the outside cement walls of a pump station, which was under construction. Employee #1 was using a roller to apply the sealant vertically overhead. The sealant dripped onto his face, arms, and legs and coated the leather gloves worn, soaking through to the skin. Employee #1 was also standing in the sealant which had accumulated on the floor of the trench soaking through the Employee #1's steel toe boots. Employee #1 was treated for chemical burns to the face, arms, hands, legs and feet. The trench and the wall height of the pump station was 26 ft high by 4 ft wide.
