A Fed Ex semi-truck was travelling westbound near FM 1463 around midnight when the driver noticed liquid spilling from the vehicle. It turned out to be a 55-gallon drum of sodium hydroxide that was leaking, spilling all over the road and packages on board.
The westbound lanes were partially closed four hours as HazMat crews cleaned the spill. The accident was cleared at 4:30am.
Sodium hydroxide is found in many cleaning products, and is poisonous if touched or inhaled.
