Section 5110.3 - Process Safety Information(a) The owner or operator shall develop and maintain a compilation of written process safety information before conducting any PHA, Hierarchy of Hazard Control Analysis, Safeguard Protection Analysis, or Damage Mechanism Review, as required by this Article. The compilation of written process safety information shall be sufficient to enable the owner or operator and the employees involved in operating or maintaining a process to identify and understand the hazards posed by the process. This process safety information shall include information pertaining to (1) the hazards of any highly hazardous materials used or produced by the process; (2) the technology of the process; (3) process equipment used in the process; and (4) results of previous Damage Mechanism Reviews. The process safety information shall be made available to all employees and relevant process safety information shall be made available to affected employees of contractors. Information pertaining to the hazards of the process shall be effectively communicated to all affected employees.(b) Information pertaining to hazards of substances used in, present in or produced by the process shall include at least the following:(1) Toxicity information, including acute and chronic health hazards;(2) California Permissible exposure limits (PELs);(3) For regulated substances: American Conference of Governmental Industrial Hygienists (ACGIH) Emergency Response Planning Guideline values, U.S. EPA Acute Exposure Guideline Levels (AEGLs), and the California Office of Environmental Health Hazard Assessment (OEHHA) acute and eight-hour Reference Exposure Levels (RELs);(6) Thermal and chemical stability data;(8) Hazardous effects of incompatible mixtures that could foreseeably occur.(c) Information pertaining to the technology of the process shall include at least the items specified in paragraphs (c)(1) through (c)(5). Safety Data Sheets meeting the requirements of section of Title 85194(g) of Title 8 of CCR may be used to comply with this requirement to the extent they contain the information required by this subsection. (1) A block flow diagram or simplified process flow diagram;(3) Maximum intended inventory;(4) Safe upper and lower limits for process variables such as temperatures, pressures, flows, levels, and compositions; and,(5) The consequences of deviations, including chemical mixing or reactions that may affect the safety and health of employees or the public.(d) Information pertaining to the process equipment shall include at least the following: (1) Materials of construction;(2) Piping and instrument diagrams (P&ID's);(3) Electrical classification;(4) Relief system design and design basis;(5) Ventilation system design;(6) Design codes and standards employed, including design conditions and operating limits;(7) Material and energy balances for processes built after June 21, 1999 and previously covered under Program 3, and material and energy balances for all other processes as of the effective date of this Article;(8) Safety systems, such as interlocks, detection and suppression systems; and(9) Electrical supply and distribution systems.(e) The owner or operator shall document that process equipment complies with recognized and generally accepted good engineering practices (RAGAGEP), where RAGAGEP has been established for that process equipment, or with other more protective internal practices that ensure safe operation. If the owner or operator installs new process equipment for which no RAGAGEP exists, the owner or operator shall document that the equipment is designed, constructed, installed, maintained, inspected, tested and operated in a safe manner.(f) If existing process equipment was designed and constructed in accordance with codes, standards, or practices that are no longer in general use, the owner or operator shall document that the process equipment is designed, installed, maintained, inspected, tested, and operating in a safe manner for its intended purpose.Cal.
