A polyvinyl alcohol (PVA) holding tank and pipelines were being flushed. Investigation shows that the employee was standing on a flange 2 ft. off ground to adjust an overhead valve. EE's foot slipped and turned a ground level valve that sprayed a mixture of 99% water and 1% PVA at a temperature of 210 F onto EE's left inner calf resulting in second-degree burns.
