What caused the Wyoming gas field explosion? Authorities are not sure yet, but an investigation is taking place over the weekend. The investigation is being led by the Occupational Safety and Health Administration, the federal agency responsible for enforcing health and safety regulations.
“We know that some welding work was being conducted on the condensate tanks on location, however the exact reason for the explosion is not known at this time,” Bridget Ford, a spokeswoman for EnCana Oil & Gas (USA) Inc., told Reuters.
