Text For Citation: 01 Item/Group: 042 Hazard:

29 CFR 1910.119(j)(4)(iii): The frequency of inspections and tests of process equipment shall be consistent with applicable manufacturers' recommendations and good engineering practices, and more frequently if determined to be necessary by prior operating experience: a. 38R receiver: An internal inspection had not been performed on the 38R vessel (the 38 receiver) since September 1994. b. 45R reactor inspection and tests (thickness testing) were not performed in a frequency consistent with good engineering practices. Thickness testing had not been performed since testing that resulted in a February 2011 thickness measurement that was 0.001 inches above the manufacturer's minimum thickness. Since the reported corrosion rate was 0.001 inches per year, good engineering practices (API 510) would require the next thickness measurement be taken by February 2012. c. 40R reactor: The 2 inch rupture disk (Carbonne Graphilor) vessel relief device was due for replacement in 2010. There was no documentation of replacement. PSI for the 40R reactor process lists a pressure relief valve for the vessel, a pressure relief valve for the jacket and a rupture disk for the jacket. There is no information for these devices having been properly maintained, inspected, recertified or replaced. d. R32-01 (20 reactor chlorination): A 3 inch pressure relief valve (Crosby JLT-JOS-15J) was past due for testing/inspection and two 3 inch rupture disks were past due for inspection and replacement. e. 18R reactor a 4 inch rupture disk was past due for inspection and replacement. f. 19R reactor a 4 inch rupture disk was past due for inspection and replacement. g. 49R reactor a 3 inch pressure relief valve (Crosby) is past due for testing/inspection and two 3 inch rupture disks were past due for inspection and replacement. h. 4R reactor: A 2 inch x 2 inch pressure relief valve (Consolidated) was past due for testing/inspection and a 2 inch rupture disk (Carbonne Graphilor) was past due for inspection and replacement. i. 5R reactor: A 2 inch rupture disk (Carbonne Graphilor) was past due for inspection and replacement. j. 58R reactor: A 4 inch rupture disk (Carbonne Graphilor) was past due for inspection and replacement. k. 41R reactor: A 3 inch rupture disk was past due for inspection and replacement.
