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

29 CFR 1910.119(e)(3)(v): The process hazard analysis did not address the hazards related to facility siting: a) Philadelphia Energy Solutions Refinery Complex, 3144 Passyunk Ave, Philadelphia, PA 19145 - HF Alkylation Unit 433: On or about June 21, 2019, the employer's facility siting study did not evaluate consequences of boiling liquid expanding vapor explosions (BLEVEs), fireballs and vapor cloud explosion impacts from BLEVEs onto equipment and piping located in Unit 433. Employees working on and in the vicinity of equipment containing highly hazardous chemicals are exposed to fire, explosion, BLEVE fragmentation, toxic, and corrosive hazards. b) Philadelphia Energy Solutions Refinery Complex, 3144 Passyunk Ave, Philadelphia, PA 19145 - HF Alkylation Unit 433: On or about June 21, 2019, the employer's facility siting study did not evaluate jet fire impacts (e.g., heat flux and dose) from a P-14A/B discharge piping release scenario onto V-1, and V-6. Employees working on and in the vicinity of equipment containing highly hazardous chemicals are exposed to fire, explosion, BLEVE fragmentation hazards, toxic, and corrosives hazards. c) Philadelphia Energy Solutions Refinery Complex, 3144 Passyunk Ave, Philadelphia, PA 19145 - HF Alkylation Unit 433: On or about June 21, 2019, the employer's facility siting study did not address a suitable location and survivability of the HF Spray Mitigation Pump House such that its pumps are available for mitigating a release of HF and fire in the unit. The Mitigation Pump House was in close proximity to process area serving V-1, V-6, and P-14A/B and was damaged during fire, explosion and BLEVE event. Employees working on and in the vicinity of equipment containing highly hazardous chemicals are exposed to fire, explosion, BLEVE fragmentation hazards, toxic, and corrosive hazards.
