A chemical spill at a plating company on Monday forced the evacuation of about 50 people working in the plant and other nearby businesses, fire officials said.
About 100 pounds of sodium hydrosulfite spilled at Platecorp, 1223 N. Batavia St., about 5:30 p.m., authorities said.
Hazardous material teams from Santa Ana and Anaheim assisted Orange firefighters in containing the spill that had the "potential to be highly toxic when mixed with water," Orange County fire dispatcher John Shope said.
"People from the plant and adjacent businesses were evacuated as a precaution," Shope said.
No one was injured during the incident, he said.
Fire officials closed North Batavia Street between Katella Avenue and Struck Avenue for several hours while fire crews mopped up the chemical.
Officials with the Orange County Health Care and Environmental Management agencies and the Southern California Air Quality Management District were notified of the spill.
