In February 2017, three contractors were fatally injured and seven contractors sustained injuries in an explosion at the Packaging Corporation of America facility in DeRidder, LA. The fatally injured contractors were conducting hot work activities near a tank which contained a flammable atmosphere which exploded.
This incident has many similarities with other fatal accidents investigated by the CSB in recent years. Collectively, they graphically illustrate the dangers of undertaking hot work without understanding the hazards and taking the necessary precautions.
