Overdue Inspections

Piping inspections for in-service equipment that have not been performed by their established due dates documented in the inspection schedule/plan and that do not have an approved deferral per 7.10. A piping system not currently in operation due to a process outage would not be considered overdue for inspection if its due date coincides with the time it is out-of-service; however, it would be overdue for inspection if it were placed back in-service before being inspected.

Oxygen-efficient Atmosphere

Oxygen-efficient Atmosphere

Definition(s)


Oxygen-efficient Atmosphere

An atmosphere in which the oxygen content is below that needed for normal human function without impairment. For inert entry, the typical oxygen content (below 5 % in inert entry situations) is very much less than the oxygen-deficient definition often used (e.g. by OSHA) of “atmosphere containing less than 19.5 percent oxygen by volume” (the OSHA limit is appropriate for areas outside the “hot zone”). Inert entry requires much lower oxygen concentration percentages to provide a working environment minimizing fire hazards by maintaining the oxygen level low enough to prevent combustion.
