What this inspection record means

OSHA opens inspections for many reasons — routine scheduling under a national or local emphasis program, an employee complaint or referral, or a follow-up after a reported injury. Opening or conducting an inspection is not itself an allegation or a finding that this employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

Initial $7,000 · Current $0 Reduced
29 CFR 1910.119(j)(4)(ii): Inspection and testing procedures shall follow recognized and generally accepted good engineering practices.   On or about May 22, 2013, the employer operated four Coker unit drums (D-1, D-2, D-3 and D-4) in continuous service for 55 years, and two Coker unit drums (D-10 and D-11) in continuous service for 29 years. All six drums had a well-documented history of frequent and on-going mechanical problems and repairs. The employer had not assessed the drums according to the 2007 ANSI/API/579-1/ASME "Fitness-for-Service" Standard ("Level 3"). The employer did not confirm that the drums were safe to continue in-service within the limits of critical operating parameters, with stipulated and appropriate on-going monitoring of their mechanical condition, and necessary repairs, for a determined period of time. Alternatively, the employer did not determine whether any or all of the drums should be retired or replaced. Employee(s) were thereby exposed to the hazards associated with fires and explosions.
