The Woodhorn pit disaster happened on 13 August 1916 when 13 men died, the youngest was 21, the oldest 48. Reason for the disaster was a build up of gases, then ingnited by a naked flame. The Durham Mining Museum website says 'there can be no doubt that this loss would not have occurred if the officials concerned had made a proper examination before commencing work. Had they done so they would have discovered the presence of inflammable gas, or would have noticed that there was not a ventilating current sufficient to carry away any firedamp that might be given off.'
