Newark deaths: Inflammable foam 'used before house explosion' 10 December 2013 Last updated at 14:57 A man whose wife and father were killed in a house explosion has told an inquest inflammable foam was being used in a DIY job in his cellar at the time. Nicholas Rourke said the explosion happened as he was walking to the door of his Nottinghamshire house in May. Jeanette and Leslie Rourke died in the blast in Wright Street, Newark. Mr Rourke told Nottingham Coroner's Court the foam, which was being used by his father, was labelled inflammable but not explosive. He said his father had come to the house to help fit a central heating system. The inquest heard the 71-year-old had been filling up an old coal chute with the expanding foam to treat damp in the cellar. Mr Rourke said the cellar door and other windows in the house had been left open to provide ventilation. He added that the instructions for the foam said it was inflammable but not explosive. He said that he "did not have as clue" what had happened in the moments after the blast, but did remember being carried across the street by people who pulled him out of the rubble. He suffered cuts to his face and needed hospital treatment.
