PURPOSE:
The Occupational Safety and Health Administration (OSHA) Process Safety Management (PSM) element and the corresponding Environmental Protection Agency (EPA) Risk Management Program (RM Program) element relating to Process Safety Information (PSI), is to ensure that there is a complete compilation of written process safety information pertaining to the PSM / RM program covered process.
SCOPE:
This document summarizes how DELHAIZE AMERICA LLC complies with the requirements of the PSM, Process Safety Information element, 29 CFR §1910.119 (d), and the EPA’s RM program, Process Safety Information element, 40 CFR §68.65 for the ammonia refrigeration system. The process safety information requirement is intended to provide an adequate database to support the required elements of a process safety management program. Process safety information is needed:
  • to document formally the as-built/as-modified condition of the plant;
  • to provide the necessary data with which to perform the required hazard analysis and hazard assessment;
  • to provide the necessary data to support other process safety management policy, procedure, and practice elements, such as standard operating procedures, and emergency response and management of change procedures; and
  • to communicate information on hazardous substances to employees and others as required by state or federal regulations.

DEFINITIONS:
Equipment Specifications:
The most important information available about the operation of equipment and subsystems in the ammonia refrigeration system is located in the facility’s installation, operation and maintenance manuals. These manuals are kept in the refrigeration office.
Good Practice:
All systems and equipment have been designed, fabricated, or installed in accordance with, at a minimum, the following codes and/or standards, as applicable:
  • ANSI/IIAR 2, American National Standard for Equipment, Design & Installation of Ammonia Mechanical Refrigerating Systems.

  • ANSI/ASHRAE Standard 15, Safety Code for Mechanical Refrigeration.
  • ANSI/ASHRAE Standard 34, Designation and Safety Classification of Refrigerants.
  • ASME, Boiler and Pressure Vessel Code, Division 1, Section VIII.
  • ASME/ANSI B31.5, Refrigeration Piping.
  • ANSI A13.1, Scheme for the Identification of Piping Systems.
  • ANSI/NFPA 70, National Electrical Code.

IMPLEMENTATION OVERVIEW:
For the most part, the PSM program is a subset of the EPA’s RM program requirements. Recognizing this for the process safety information requirements, and for improved implementation and program maintenance efficiency, this document has been implemented which combines both the PSM and RM program requirements. The overall compliance program is referred to as the “Process Risk Management Program”.
This document serves mainly as a reference guide to identify the types of information specified in the regulations.
The process safety information is available in the refrigeration office and on the Stellar portal.
1.0 / REQUIRED INFORMATION:
Process safety information describes certain safety attributes of ammonia, the process in which it is used, and the equipment within that process. It is comprehensive enough for an accurate assessment of all the hazards that may occur within the process during normal and upset conditions.
The process safety information is required to be compiled and maintained up-to-date. It is to be made available to all employees and is to be included, as necessary, in employee training programs. Process safety information must cover:
  • information pertaining to the hazards of ammonia;
  • information pertaining to the technology of the process; and
  • information pertaining to the equipment in the process.

1.1 / Hazards of the chemicals used in the process:
  • Physical data (i.e. boiling point temp., vapor pressure, vapor density, etc.)
  • Toxicity data (i.e. TLV, PEL, IDLH, etc.)
  • Thermal and chemical stability data (i.e. flammability limits, flash point, autoignition temp., etc.)
  • Reactivity data
  • Corrosivity data
  • Erosion effects on the process equipment
  • Monitoring equipment
  • Permissible exposure limits
  • Hazards related to mixing with other chemicals
Safety Data Sheets (SDS’s) are used in compiling information on anhydrous ammonia as a refrigerant, its chemical properties, and health and safety hazards.
1.2 / Process technology information:
  • Maximum inventory levels
  • Block Flow or Simplified Process Flow diagram
  • Safe operating limits for:
--temperature
--pressure
--flow rates
--liquid levels
  • Ramification of process deviation
The process technology information is generally included in equipment specifications, operating procedures, or on drawings.
1.3 / Process equipment:
  • Materials of construction
  • Piping and instrumentation diagrams (P&IDs)
  • Electrical classification
  • Design codes and standards

  • Pressure safety relief settings
  • Safety systems/devices
  • Ventilation system design
  • Material and energy balances (for facilities built after May 26, 1992)
  • Compliance with recognized and generally accepted good engineering practices

2.0 / PIPING AND INSTRUMENTATION DIAGRAM (P&ID):
2.1 / A Piping and Instrumentation Diagram (P&ID) is a mechanical schematic drawing of the plant refrigeration equipment. Details such as piping, relief valves, refrigeration control valve type, valves, instruments, line numbers, and refrigeration equipment are shown on the P&ID. The P&ID, while not drawn to scale, does show relative sizes and locations. Instrumentation including such details as tie-in points, instrument numbers, control valve numbers, and panel or local control mounting details are shown. A list of the P&IDs are listed in Appendix A
2.2 / A title sheet or legend is available for all the P&IDs. It contains a complete legend of the symbol and abbreviations used on the refrigeration system P&IDs
2.3 / Each piece of equipment is labeled and may be assigned a numerical abbreviation. Abbreviations are correlated to names on the equipment list.
2.4 / Major equipment, valving, instruments, and safety systems are also shown on the P&IDs.
