29 CFR 1910.119(j)(4)(iii): The frequency of inspections and tests of process equipment was not consistent with applicable manufacturers' recommendations and good engineering practices, and more frequently if determined to be necessary by prior operating experience. For the ammonia process, as observed on or about/between 07/07/2016 - 08/31/2016, the following equipment was not inspected with the frequency specified in the manufacturer's recommendations, employers procedures, or good engineering practice: a) Sensidyne ammonia sensors were calibrated annually while the manufacturer specifies a calibration frequency of once every 90 days. Bump tests were also not performed on a regular basis. b) Ammonia piping 5-year audits/inspections were not conducted in the last five years as the employer's inspection frequency and selected industry design standards specified. The last time piping inspections were conducted that included non-destructive testing was in 2009.
