A tanker truck locked bumpers with an automobile on the Capital Beltway at the end of rush hour last night, flipped over on its side and leaked a small amount of its cargo, ferric chloride. State police closed the highway in both directions to clear the wreckage.
The truck driver, who was identified only as a 54-year-old man, was taken to Southern Maryland Hospital with minor injuries, according to Maryland State Police spokesman Cpl. Rob Moroney. The driver of the car, a 42-year-old man, was being treated at the trauma unit of Prince George's Hospital Center, as were three Prince George's County police officers who were overcome by fumes from the truck's cargo.
State police reopened the outer loop about 9 p.m., but the inner loop remained closed late last night while officials waited for a hazardous materials contractor to unload the chemicals, which are used to treat sewage, and to clean up the spill.
