CCTV Utah refinery explosion. Workers caught in explosion.

Newly released CCTV video shows the moment a fiery gas explosion ripped through a Utah refinery earlier this month. The U.S. Chemical Safety Board on Tuesday released the video and its preliminary findings of what led to the November 4th blast at the Silver Eagle Refinery in Woods Cross. The blast damaged 10 homes but caused no serious injuries. On Friday, board Chairman John Bresland recommended that the plant shut down as quickly as possible. He says investigators in recent days developed serious concerns about the plantapos;s equipment. He says the plant could be restarted once any needed repairs are made and investigators can determine itapos;s safe to reopen. Silver Eagle confirmed it agreed to the shutdown. Investigators havenapos;t made a final determination on what caused the blast. Preliminary findings indicate that the explosion happened when a 10-inch (25,4 centimetres) pipe failed catastrophically. On January 12th, four people were seriously burned at Silver Eagle when a 440,000 gallon (1,665,581.2 litres) storage tank caught fire and burned for 11 hours. The refinery in Woods Cross had fires in 2003, 2005 and 2007, according to federal records.
