Text For Citation: 01 Item/Group: 013 Hazard:

29 CFR 1910.119(j)(6)(iii): The employer shall assure that maintenance materials, spare parts and equipment are suitable for the process application for which they will be used. (a) On or about April 3, 2014 the Teflon expansion joint made by Ethylene installed at the discharge dump line from bottom of Stage 1 Reactor R-109 to the dump line to Outlet Reaction Buffer Drum Tank D-101 was not suitable for the piping where it was used because: 1. The expansion joint was dimensionally too short. 2. The expansion joint was installed into a piping system where thermal pipe growth from steaming resulted in lateral deflection forces on the expansion joint that resulted in its misalignment beyond the manufacturers limits for lateral misalignment of 0.67 inches. 3. The dump line piping system was not fitted a device or a work practice (condensate bleed) to ameliorate pressure liquid momentum surges (e.g. water hammer). 4. The failed R-109 expansion joint would experience temperatures and pressures exceeding the manufacturers recommended limits if subject to available steaming pressures of 75 psig and 150 psig. In accordance with 29 CFR 1903.19(d), abatement certification is required for this violation (using the CERTIFICATION OF CORRECTIVE ACTION WORKSHEET), and in addition, documentation demonstrating that abatement is complete must be included with your certification. This documentation may include, but is not limited to, evidence of the purchase or repair of the equipment, photographic or video evidence, or written records.
