31 California aerospace workers exposed to unknown chemical

Eight employees at a Southern California aerospace facility were taken to a hospital after being exposed to an unknown chemical that caused them breathing problems.

Los Angeles County Fire spokesman Sal Alvarado says 31 employees at TA Aerospace in Santa Clarita were exposed to powder chemicals in the process of being mixed on Monday night.

Alvarado says many of the employees were coughing after the exposure and that at least six of the employees were in fair condition when they were taken to the hospital.

It's unclear whether any of them remain hospitalized.

Alvarado didn't know what chemicals were involved in the exposure.

A phone message left at TA Aerospace wasn't returned Tuesday. The company makes clamps, insulation and other materials for the aerospace industry.
