McGuire, Paul Thomas

Male·Asphyxia, caused by the inhalation of severely oxygen-depleted air

Paul McGuire, an experienced mine electrician, died from asphyxiation after opening a partially sealed hatch door to a GOAF (worked-out coal area) containing severely oxygen-depleted air. The critical failure was the mine's grossly deficient record-keeping system: job cards contained outdated sensor location information that was never updated despite multiple workers noting corrections. A sensor relocation in January 2014 was never reflected in the job card generation system. McGuire's card directed him to an incorrect location where he encountered an inadequately sealed hatch with no warning signs. The hatch was secured by only one bolt and lacked barrier tape or other physical deterrents. Systemic failures included: inadequate checking of completed job cards, failure to update the source system, absence of warning signage on the dangerous door, and insufficient physical barriers. The coroner found the mine's record-keeping was the most significant contributing factor. Recommendations included developing hatch seal design guidelines, improving signage and access controls, and allowing workers to request accompaniment by ventilation officers.
