Investigation underway into deadly chem leak at DuPont plant in Texas
A seven person go-team from the U.S. Chemical Safety Board (CSB) begins work this morning at the LaPorte DuPont plant near Houston, trying to determine what caused the toxic chemical leak that killed four workers and sent another to the hospital early Sunday morning.
The workers died when methyl mercaptan, a chemical used as feedstock to make insecticides and fungicide, was released into the air – a leak DuPont said was caused by a malfunctioning container of the gas, according to news reports.
