The US Occupational Safety and Health Administration has cited chemical firm DuPont for failure to record on-site injuries that occurred last November at a plant in Niagara Falls, New York State. DuPont failed to list injuries in the official OSHA 300 record-keeping log.

Two workers had inhaled chlorine gas and one of the two needed immediate medical attention a missed a month of work.

The violation comes following the US labour board citing DuPont for failure to turn over requested documentation by US affiliate PACE on location of hazardous chemicals at the textile fibres plant. In 2002, DuPont refused to allow PACE health and safety representatives from entering the plant.
