On November 9th, 2010, a powerful explosion occurred at the DuPont chemical manufacturing plant in Tonawanda, New York, which is a suburb of Buffalo. The explosion occurred while a contract worker was ing maintenance work on a tank that unknown to him contained flammable gas. As a result of the explosion, the top of the tank was blown off, causing the welder to be thrown to the ground and killed instantly. Another contract worker suffered burns in the tragic incident. The explosion at the DuPont facility raised questions about the analysis and control of process hazards. It highlighted the importance of properly managing hot work accidents, which occur when workers are involved in welding, cutting, or grinding activities near flammable vapors. In fact, a 2010 CSB safety bulletin specifically addressed deficiencies in the safety management of hot work.

The process of producing Tedlar involves a chemical reaction to convert flammable vinyl fluoride gas into a slurry of polyvinyl fluoride polymer (PVF) in water. The PVF slurry then undergoes separation and compression, with any unreacted vinyl fluoride gas being recycled back into the process. Residual vinyl fluoride is released into the atmosphere through a flash tank, while the slurry is stored in insulated holding tanks. The incident on October 22nd, 2010, during a planned shutdown of the Tedlar process, revealed significant corrosion on the agitator supports of tanks one and two. Dupont enlisted contractors to repair the corroded supports, which involved welding and grinding. While the repairs on tank two proceeded without incident, the work on tank one was delayed due to the need for parts. Dupont personnel determined that it would be safe to resume hot work on...
