DuPont fined millions for deadly chemical release at Texas plant.

DuPont Company has pleaded guilty and has been sentenced for criminal negligence in connection with a 2014 incident that killed four company employees. The company has been ordered to pay $12 million in fines and $4 million in Fish & Wildlife Foundation donations. The former employee, Kenneth Sandel, pleaded guilty to criminal negligence and was sentenced to one year of probation. The incident occurred after an employee inadvertently left open a piping valve, which caused a slushy material to block the flow of liquid MeSH into the Lannate process.
