Sasol is still assessing the damage from an explosion and fire at its Lake Charles plant in Louisiana a week after the incident. The explosion at the low-density polyethylene unit at Lake Charles on January 13 could be heard across southwest Louisiana and blew the hurricane doors off a fire department building located next to the plant, according to local broadcaster KPLC. The unit – one of two large polymers plants – is a key part of Lake Charles’ operations.
