Cause: The 1201 drum in the Delayed Coking Unit was on line. There was a small anti-foam and Heavy Gas Oil (HGO) carrier leaking from a flange. The leak saturated the insulation on the side of the 1201 drum. As plant insulators were working to remove the insulation, air hit the saturated insulation. When combined with the heat from the drum, a small fire was ignited.

Followup: No
