The Inglewood courthouse was evacuated Monday as a hazmat team investigated a powder that injured a worker at the clerk's office, fire officials said.
The incident was reported about 2:20 p.m. Monday, the Los Angeles County Fire Department said.
"There was someone that was opening up the package and at that point she may have passed out, as well as she had a burning sensation to her hand," said Deputy Ryan Rouzan of the Los Angeles County Sheriff’s Department.

At least one woman was taken to the hospital. She was in a white, protective suit.
Initially, only the second floor of the courthouse was evacuated. The building was later closed for the day as a precaution.
