How often do gas detectors need to be inspected, tested, and calibrated?

The simple answer is: every six months.

OSHA PSM Standard says:1910.119(j)(4)(iv): “The employer shall document each inspection and test that has been performed on process equipment. The frequency of inspections and tests of process equipment shall be consistent with applicable manufacturers’ recommendations and good engineering practices.”

The OSHA Appendix Explains: “Elements of a mechanical integrity program include… documentation of instrumental test and inspection results and documentation of manufacturer recommendations.”

Most gas detection manufacturers (including CTI) recommend calibration every 6 months.
