Four people were slightly injured when 1,000 gallons of toxic material being transported from a ship to a railroad car spilled onto a dock at Los Angeles Harbor, authorities said.
Two dock guards and two Unocal employees complained of dizziness after the chemical, a cleaning solvent identified as trichloroethane, spilled at Berth 150 Sunday night, city Fire Department spokesman Jim Wells said. Three of the victims were taken to local hospitals and the fourth was treated at the scene, Wells said.
Berth 150 was reopened about three hours after the spill, said Sgt. Martin Renteria of the Los Angeles Harbor Police.
Authorities said they did not know who was transporting the toxic material or whether Unocal was involved.
Hazardous materials specialists were able to keep the chemical from running into the harbor, Wells said.
