SANTA ANA (CBSLA) — Orange County Fire Authority officials investigated an unknown substance inside a Santa Ana federal building Tuesday evening.
The Orange County Fire Authority Hazmat team responded to the Ronald Reagan Federal Building on the 700 block of West Santa Ana Boulevard in regards to a white powdery substance.
It was not immediately clear how many people were exposed but nobody was showing any symptoms, according to the OCFA.
According to police, several people went through a decontamination protocol and were taken to an area hospital for precaution.
