An employee was taking off the access panel of the E Line Coagulation Tank to clean the excess solids out of it. As the employee was doing that the residuals (adjusted pH hot water 150-160 degrees Fahrenheit, liquid latex, and 93% sulfuric acid) splashed onto the employee. The pH of the residuals was approximately 3.2. The employee received second degree burns down the right side of his body. The employee was hospitalized.
