Eight kidney patients were evacuated from an Anaheim dialysis center Friday after a formaldehyde spill caused an "unbearable" odor for patients and staff, an Anaheim Fire Department spokesman said.
Twelve people were in the center, Neophron Inc., 2051 E. Cerritos Ave., when the pungent odor was first detected about 6 p.m., Battalion Chief Steve Magliocco said.
The patients were told to return to their homes. Firefighters from the Orange County and Anaheim fire departments used fans to blow the obnoxious odors from the center.
The patients were not harmed, Magliocco said.
Fire investigators were trying to determine the cause of the spill.
