HOPE, Ark. (AP) - The emergency room at a hospital in Hope had to shut down for seven hours to be decontaminated after treating a man covered with anhydrous ammonia when his methamphetamine lab exploded.
    
The Texarkana Gazette reports  the ER at Medical Park Hospital was closed from midnight until 7 a.m. Tuesday.
    
Hempstead County officials say emergency room workers felt a burning sensation on their skin and eyes. The man, who wasn't named by authorities, then admitted he had been making meth and his lab exploded.
    
The patient was airlifted to a Little Rock hospital and a hazardous materials cleanup team got to work in the hospital.
    
Police were unable to interview the patient before he was transported and the person who dropped him at the hospital drove away immediately.
