Abstract: At approximately 8:30 p.m. on November 19, 1998, Employee #1, a maintenance supervisor for Dreyers Grand Ice Cream Company, was dismantling a high-temperature fault on the CIP system in pasteurizing line #1. He removed the cover without using an air blow valve to check the system. The temperature and pressure of the water increased and the hot water overflowed, striking Employee #1. He suffered second-degree burns on his arms, chest, and neck, and was taken to the USC burn unit. He was subsequently transferred to the Irvine Medical Center , where he was hospitalized for six days and then treated as an outpatient.
