Inspection Summary
A construction inspection was performed on Das-co, a contractor for Intermountain Gas Company.
28 Oct 2019: (2.0 Construction)
Observed a Dasco crew excavating for a new 6" main and fusing the new 6" pipe. While observing the
fusing crew we noticed that they were not checking the iron temperature prior to fusing as per IGC
procedural requirement. Prior to the next fuse I asked them to show me what the temperature of the iron
was, they got the pyrometer and I asked to check the calibration date and it was within specs. They then
proceeded to check the temps and it was reading between 448-450 degrees, and the required temps are
500 + or— 10 degrees per IGC procedure. At that time, we contacted IGC leadership and informed them
of what had taken place and they sent IGC personnel and Das-Co to stop the job. They disqualified the
fuser, and made the site safe for the day and stopped all work. Typed up report
Areas observed during this project were: Excavating and Fusing
