Abstract: Employee #1 complained about a "burning chest," while he was at work. He was driven home by a coworker and then taken to the hospital by his parents. A physician there called Employee #1's workplace and asked for the Material Safety Data Sheets (MSDS) for any chemicals to which the worker might have been exposed. The doctor assessed this information and felt that Employee #1's condition was not related to chemicals. He was released from the hospital and driven home by his parents. Shortly after Employee #1 arrived home, he passed out. An ambulance was called and Employee #1 was transported to the hospital, where he was pronounced dead. The cause of death was an aneurysm at the beginning of the aorta, which caused heart and circulatory system failure.
