The refinery as a whole is safe, and the specific site of the incident is isolated and contained, Irving said in a news release.
The company said there are no concerns with air quality, and accordingly, the turnaround team was to be back on site for the night shift on the evening of Oct. 9.
Plans for when the refinery will resume full turnaround mode have yet to be released.
While local and national media reports have categorized the Oct. 8 incident as an explosion and subsequent fire, Irving has yet to publicly confirm the nature of the upset.
