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.
