Abstract: Employee #1, a sanitizer in the juice department of a fruit processing plant, was bailing out tank #1, which was used in the manufacture of fruit juice. This was part of his normal duty of cleaning and sanitizing the juice tanks and pipelines. The bail-out procedure calls for the tank to be filled to the top with cold water and liquid caustic, then heated to 212 degrees F for a given time. Employee #1 was adding the liquid caustic when he ran out, so he went outside to get some dry caustic powder. He turned on the heat to the tank before he left; when he returned, the tank was between 180 and 200 degrees F. Employee #1 poured in approximately 2 lb of caustic powder, which caused an immediate eruption of the liquid in the tank. The caustic mixture splashed all over the left side of his body, and he suffered second-degree burns on his arm, leg, and face. Employee #1 was hospitalized at Gridley Hospital for four days.
