Abstract: At 9:45 a.m. on July 22, 2019, an employee was conducting a routine hot rinse of a fermentation tank. After completing the rinse, the employee disassembled the cleaning equipment which still contained hot water in the vertical piping/racking arm (total length 48 to 50 inches and bent at a slight angle) adjacent to the tank. The employee forgot to close the valve and when he removed the tri-clamp fitting from the racking arm hot water sprayed into his left boot. The employee had tucked his pants into his boots and was not wearing body protection such as an apron and impermeable bib-type coveralls. The employee rinsed his left leg with cold water and was transported to the hospital, where he was treated second for degree burns to his leg and released. The employee returned for a follow up appointment on July 25, 2019, and was advised to go to a local hospital with a burn treatment unit, where he was admitted for additional treatment.
