29 CFR 1910.119(j)(5) The employer shall correct deficiencies in equipment that were outside acceptable limits (as defined by process information in 29 CFR 1910.119(d)) before further use or in a safe and timely manner when necessary means are taken to assure safe operation: (a) At the time of inspection, 10/22/09 to 2/22/10, at Tesoro Refinery and Marketing Co., 474 W 900 N, Salt Lake City, the employer did not correct the deficiency of the calibration test done on Knockout Drum's, V-107, critical high level alarm, LAH 040363. Compliance Officer's review of the quarterly calibration tests done in 2009 were noted to be from 37 percent to 53 percent and were marked as 'OK' by the inspectors. During the interviews with employees and supervisors, the critical high level alarm was set to signal when the liquid level in the knockout drum reached 62.7 percent. On the night of 10/21/09, the supervisor observed from the outside level gauge that the drum was full but the board was indicating that the drum was about 49 percent full. On 10/22/09, a quarterly calibration inspection was done on the critical high level alarm on the knockdown drum and the inspector recorded that the critical high level alarm was reading about 53 percent full. The inspector wrote in his report as 'OK' indicating that the level alarm was functioning properly. No further work was done on the level alarm system to correct the deficiency to ensure the correct level in the drum was being reported to the Board Operator. Serious injury or death may occur if proper levels in vessels are not known by employees.
