The Westray Mine Disaster

ClosedSources: ALast updated: 14 October 2026

At 5:18 am on 9 May 1992, methane gas ignited in the Westray coal mine in Pictou County, Nova Scotia, setting off a massive coal-dust explosion. All 26 miners working underground were killed; a week of rescue efforts found no survivors. The mine had opened only eight months earlier despite a legislator's warning about its dangers. The public inquiry report published in 1997 found that the mine had been mismanaged, worker safety ignored and regulatory oversight inadequate. A criminal case against two managers was dropped in 1998. The disaster led to the 2004 'Westray Law', which introduced criminal liability for corporations and their managers.
