Canada concrete plant dust explosion injures three
06 November 2018
A November 5 dust explosion at the Quality Concrete plant in Dartmouth, Nova Scotia, resulted in three minor injuries, according to CBC. The explosion blew the roof off a fly ash silo, propelling it hundreds of metres where it fell on a parked vehicle. Fly ash is an extremely fine powder that is mixed with cement in the production of concrete.
Stephen Nearing, division chief with the Halifax fire department, said more than a dozen workers at the site were covered with fly ash Monday. The dust coated streets, lawns and vehicles in the area after the explosion. Nearing said fly ash is a known carcinogen.
Inspectors from the provincial Labour Department and its Occupational Health and Safety Division are investigating the blast. A stop work order has been issued as the investigation continues.
Quality Concrete has 17 plants across Nova Scotia and the Maritimes and is owned by the Stevens Group.
