Incredible CCTV footage shows the moment a worker had a miracle escape after he was sent flying through the air by a huge underground gas explosion. The man had been building a fence on a farm in Wessington near Alfreton, Derbys., when he was blown off his feet by the force of the blast on Tuesday (21/6). The contractor can be seen scrambling to safety after the machinery he was using struck a gas main forcing 30 homes to be evacuated. Fire crews and gas engineers rushed to the scene to make the area safe as gas poured from the ruptured pipe. A Cadent spokesperson said: "Cadent engineers worked through the night on an emergency repair after a pipe was hit by a third party on Brackenfield Lane in Wessington on the morning of 21 June. "Our teams have made everything safe and remain on site to complete the repair work. "There has been no interruption to the local gas supply. Households that were evacuated yesterday as a safety precaution have now been able to return home. "We’d like to thank everyone for their patience. "This was a great response by the emergency services, including our team, in making sure everyone was kept safe. "If you ever smell gas, here or anywhere, it is important to act immediately and call the national gas emergency service on 0800 111 999."
