Cause of third fire at Regina Co-op refinery explained
A vent plug failed causing of a fire damaging buildings and equipment at the Co-op Refinery last month in Regina, the third significant fire at the refinery in the last year and a half.
The latest fire started around midnight Feb. 11 when a carbon steel vent plug failed because of sulfidation, a type of chemical reaction. The Regina Fire Department says this led to extreme pressure and extremely high temperatures which caused the fire.
Some witnesses described seeing flames up to 80 feet high and a lot of smoke that night.
Later that day, Vic Huard, Co-op's vice-president of corporate affairs, offered a bit more detail.
