Officials have identified the employee at a Los Angeles biotechnology plant who died while trying to help two colleagues who had been overcome by toxic fumes.
The Los Angeles County coroner's office said Saturday that 33-year-old Henry Astilla of Los Angeles died at a hospital after paramedics found him without a pulse at the Atwater Village facility of Baxter International.
The Los Angeles Fire Department says Astilla called 911 early Friday after noticing two co-workers had collapsed while cleaning blood plasma from a tank. They were overcome by ethanol, which was used as a separating agent for blood plasma.
The other two men survived. Their names have not been released.
Investigators from the California Division of Occupational Safety and Health, known as Cal-OSHA, are investigating.
