29 CFR 1910.119(e)(3): The process hazard analysis (PHA) shall address: 29 CFR 1910.119(e)(3)(i): The hazards of the process: a. As of December 21, 2015, the employer's Final PHA Study Report of the Sterols Plant dated June 2011, failed to adequately identify all potential worst case scenarios which could lead to an over pressurization of the TK 0401-00 Melt Tank and the connected vessels, such as the F 0302-00 South RDF. b. As of December 21, 2015, the employer's Final PHA Study Report of the Sterols Plant dated June 2011, failed to adequately identify the potential for the hexane solvent wash to create a situation which could result in rapid boiling of the hexane under upset conditions where the TK 0401-00 Melt Tank contained frozen or partially frozen sterol. c. As of December 21, 2015, the employer's Final PHA Study Report of the Sterols Plant dated June 2011, failed to adequately identify all potential worst case scenarios that could lead to over pressurization in the E 0502-00 Evaporator and adequately consider the hazards associated with the emergency relief of the E 0502-00 Evaporator into the TK 0710-00 Solvent Storage Tank. d. As of December 21, 2015, the employer's Final PHA Study Report of the Sterols Plant dated June 2011, failed to adequately identify the hazard associated with the material build-up in the cross-hatched metal end of the relief pipe on the TK 0401-00 Melt Tank when material was discharged through the rupture disc line.
