One person is confirmed dead and another seriously injured after 10,000 gallon tanker exploded at the DuPont plant on River Road in Tonawanda. The tanker, which is normally filled with the chemical known as poly vinyl fluoride, exploded around 11:10 a.m., but was empty. A large response of fire, EMS, police and HazMat teams responded to the scene. Town of Tonawanda Police say two men were working on the tanker for an outside contractor when the tank exploded. One victim was killed and the other was transported to an area hospital with serious chemical burns. The exact cause of the explosion is unknown at this time and several internal investigations are underway. OSHA also responded to the explosion. As a result of the explosion, the Adult Education classes at the Ken-Ton Boces Center have been canceled for Tuesday night, however Tonawanda Engine 2nd shift employees were instructed to report as normal as the explosion does not pose any risk to employees. DuPont manufactures a number of products used in the building industry for counter-top installations, wall cladding and a polyvinyl fluoride film used for covering applications. The Buffalo area plant was first established in 1921.
