Lessons Learned: Nitrogen Oxide heavier than air properties along with the Process Gas Systems large Bore Piping and components configurations, coupled with a practice of applying plastic covers over the system openings allowed the Nitrogen Oxide to accumulate to high levels in the system interior. As workers moved to different locations in the work area the air inlet of their Powered Air Purifying Respirator (PAPR) could infrequently be located near the system cut openings that were not yet covered and some of the escaping Nitrogen Oxide could be drawn into the PAPR. The PAPR filter employed is not NIOSH-certified to protect against Nitrogen Oxide.
