Abstract: At approximately 2:00 p.m. on June 23, 2000, Employee #1, an operator helper for a manufacturer of cardboard containers, was sweeping the area next to the supervisor's office, approximately 20 ft south of paper machine # 2, when it exploded without warning. He ran outside the building through the gate next to the high voltage area. He then heard a second explosion, followed by a third. As he was running, he was struck by a flying piece of metal on his left buttock, and he began to bleed profusely. Employee #1 sustained a 1 1/2 in. long perineal laceration between his scrotum and his rectum. Paramedics arrived and he was initially taken to a local clinic. Employee #1 was then transported to Whittier Presbyterian Hospital, where he treated for two days and then released.
