NEWARK -- An employee at a lumber company in Newark was treated at a hospital Friday morning after a drum containing an unidentified chemical was knocked over by a forklift, an Alameda County fire spokeswoman said.
The substance in the 5-gallon container was unknown to workers at Hulbert Lumber, 37500 Cedar Blvd., said Alameda County fire spokeswoman Aisha Knowles. The container was not labeled.
A forklift driver was moving items from a storage room about 9 a.m. when he accidentally tipped over two containers, knocking the lid off one, she said.
A small amount of liquid was spilled and two employees tried to clean it up, but one fainted and was taken to the hospital. Eleven other employees evacuated the business, but the evacuation order was lifted about 1 p.m. and they returned to work, Knowles said.
The man who was taken to the hospital was treated and released and no one else was injured, she said.
The Alameda County hazardous materials crew tested the liquid and sent it to a lab for further testing. It should be identified in the coming days, she said.
No other businesses or homes in the area were affected by the spill.
Newark police assisted at the scene.
