Text For Citation: 01 Item/Group: 005 Hazard:

29 CFR 1910.119(j)(4)(i): The employer did not perform inspections and tests on process equipment for mechanical integrity. On or about 16 July 2012, and at times prior thereto, the employer did not perform inspections and tests of the process equipment involved with the ammonia system, exposing personnel to ammonia hazards. Such inspections and tests would involve non-destructive methods for evaluations, to include ultrasonic thickness testing on piping, vessels, and valves. a) The manufacturer of the Pressure Vessel for the ammonia storage, Babcock & Wilcox, suggested that annually the gauges for the system be calibrated with certified equipment, and that insulated piping be inspected for corrosion. Neither of these steps was being administered after ~ 2 years of being in service. Pursuant to 29 C.F.R. 1903.19, within ten (10) calendar days of the date of this citation, the employer must submit documentation showing that it is in compliance with the standard, including describing the steps that it is taking to ensure inspections and tests are being performed on process equipment, to include non-destructive testing and evaluations.
