29 CFR 1910.119(d)(3)(i)(B): Process safety information pertaining to the equipment in the process did not include the piping and instrument diagrams: The employer did not ensure the Piping and Instrumentation Diagrams (P&ID) were correct and up to date. Field verification of valves identified several inaccuracies in the P&ID. The following valves were not labeled correctly: (a)Valve tags reversed manipulated during unloading: GS GF2 HV203 and GS GF2 HV209. (b)Valve tags reversed manipulated during unloading: GS HFNTR HV202 and GS HFNTR HV208. (c)Dual relief header downstream #1 HF Tank rupture disc tags reversed: RD 604 and RD 605. (d)Dual relief header downstream #1 HF Tank valve tags reversed: HF U256 HV003 and HV U256 HV002. (e)Dual relief header downstream #1 HF Tank common vent line not marked from RV 606 and RV607. (f)Rupture disk RD660 on HF Dump Tank was not labeled. (g)Dump valves HF U256 AV006 & HF U256 HV015 for tank #1 were field verified on Tank #3. (h)Dump valves HF U256 AV004 & HF U256 HV013 for Tank #3 were field verified on Tank #1. (i)Relief valves on HF Dump Tank U-256 were reversed. RV610 & RV653 were reversed. (j)Relief valves on Tank #2 U-404 were reversed. RV412 & RV413 were reversed. (k)Valve between the inlet RD and RV on Tank #1 had a ball valve listed as HF RD605 HV001, field verification determined valve was labeled HF RD605 HV004. (l)Block valve from HF Dump Tank U-256 was listed as HF U827 HV004, field verification determined that it was labeled HF U287 HV004. (m)Block valve from HF Dump Tank U-256 was listed as HF HFSTG HV006, field verification determined it was labeled HF HFSTG HV007. (n)On Ammonia Storage Tank U-466, the relief valves RV423 & RV422 were reversed. (o)Ammonia unloading line had block valve listed as NH3 LIQSTG HV008, field verification determined it was labeled NH3 LIQSTG HV003. (p)Ammonia vent line had block valve listed as NH3 P404 HV005, field verifiaction determined it was labeled NH3 P404 HV003. (q)Three way valve coming off of Ammonia tank U-466 was not identified on PID. (r)Three way valve coming off of Ammonia tank U-467 was not identified on PID. (s)Relief valve on Ammonia tank U-466 was listed as RV668, field verification indicated it was RV666. There were two RV666 in the field. Abatement documentation is required for this item in accordance with the requirements of 29 CFR 1903.19(d).
