Southern California Edison is continuing to investigate a strong odor that led to the evacuation of about 300 employees at its Long Beach call center Monday.
Seven employees were taken to area hospitals and 23 others were treated on scene for symptoms, including nausea and headaches. All seven have been released from the hospitals, according to a SCE press release.
The odor was detected at 10 a.m. Monday. After the fire department sent a hazmat crew into the building to conduct an air analysis, authorities ordered the evacuation around noon. No other nearby buildings were affected.
The fire department cleared the building around 5 p.m. Monday.
Evacuated employees were later allowed to retrieve their cars and go home. Some of the call center’s employees will work from another SCE facility, according to the press release.
