"..................................Universal Colliery (1891-1928) was in Senghenydd (Wales). Two fatal accidents occurred there; in 1901 (81 killed), and in 1913 (439 killed), with the 1913 accident being the biggest mining disaster in Great Britain. During the enquiry into the disaster, several breaches of regulations were uncovered, the most serious of these was the inability of the ventilating fans to reverse the airflow. Legislation had required that all mines should have implemented this by January 1st 1913. It was estimated if the current of air had been reversed a hundred lives might have been saved."
