Around 10:18 am yesterday, a blast was reported at Encana Corp's Antelope 91-29H facility, a natural gas field established on the Jonah Field of western Wyoming.
According to NBC News, firefighters extinguished the flames by 1 p.m. that same day, but not before the fire left one worker in critical condition, another in serious condition and two more in stable condition. The fifth injured worker was treated and released from a hospital that same day.
The scene is now being investigated by The Occupational Safety and Health Administration to determine the cause of the explosion.
Condensate tanks on location were undergoing welding work, but the spokeswoman of Encana Oil & Gas USA says that the company is not sure if that caused the explosion. Condensate tanks, which hold high amounts of pressurized steam, have the potential to be highly explosive.
Our thoughts are with the injured and their families as we wish them a speedy recovery.
