A small fire flared up in the Bio-Rad Laboratories facility on Regatta Boulevard in Richmond around 9:30 a.m. Sunday, but no hazardous materials were released and firefighters extinguished the blaze almost immediately, a battalion chief said.

The fire started in laboratory equipment, damaging one room at the lab, said Battalion Chief Byron Berhel of the Richmond Fire Department. Bio-Rad employees were at work cleaning up smoke damage Sunday afternoon, according to Berhel.

Hercules-based Bio-Rad makes life science research and clinical diagnostic products and has facilities around the world.
