CTV: One dead, three injured at Polymer Source in Montreal

Via CTV: 

An explosion at a polymer research centre Friday in the Montreal suburb of Dorval left one dead and at least three injured. 

Paramedics received a 911 call at around 11:30 a.m. for a report of an explosion. They said a 40-year-old man was pronounced dead at the scene, and two others were sent to hospital for non-life-threatening injuries. A third worker who was injured refused to be sent to hospital. 

The explosion happened at the Polymer Source, a company that describes itself as a supplier of high-quality polymers and bio-polymers for academic and pharmaceutical and industrial research.

Three teams of paramedics responded to the scene. Firefighters were also on site. 

Reaction on Twitter indicates that this is a well-known source of research material. Condolences to the families and friends of those killed and injured. 


  1. I wonder if the explosion was due to work with ethylene oxide - that stuff is nasty, it burns even without oxygen. Polymer Source was manufacturing PEGs/PEOs

    1. Rohm & Haas divested the Triton surfactant line to Dow many years ago (long before Dow acquired the rest of R&H) for exactly this reason. Too much risk of something going wrong.

    2. thermal runaway with EO polymerization can turn deadly, especially after the polymerization was previously done hundred times "safely" without a problem, by some unanticipated quirk or equipment malfunction or a small change in the setup
