PROCESS SAFETY INFORMATION:
Employers must complete a compilation of written process safety information before conducting any process hazard analysis required by the standard. The compilation of written process safety information, completed under the same schedule required for process hazard analyses, will help the employer and the employees involved in operating the process to identify and understand the hazards posed by those processes involving highly hazardous chemicals. Process safety information must include information on the hazards of the highly hazardous chemicals used or produced by the process, information on the technology of the process, and information on the equipment in the process. Information on the hazards of the highly hazardous chemicals in the process shall consist of at least the following:
• Permissible exposure limits,
• Physical data,
• Reactivity data,
• Corrosivity data, and
• Thermal and chemical stability data, and hazardous effects of inadvertent mixing of different materials. Information on the technology of the process must include at least the following:
• A block flow diagram or simplified process flow diagram,
• Process chemistry,
• Maximum intended inventory,
• Safe upper and lower limits for such items as temperatures, pressures, flows or compositions, and • An evaluation of the consequences of deviations, including those affecting the safety and health of employees. Where the original technical information no longer exists, such information may be developed in conjunction with the process hazard analysis in sufficient detail to support the analysis. Information on the equipment in the process must include the following:
• Materials of construction,
• Piping and instrument diagrams (P&lDs),
• Electrical classification,
• Relief system design and design basis,
• Ventilation system design,
• Design codes and standards employed,
• Material and energy balances for processes built after May 26, 1992, and
• Safety systems (e.g., interlocks, detection or suppression systems) .
The employer shall document that equipment complies with recognized and generally accepted good engineering practices. For existing equipment designed and constructed in accordance with codes, standards, or practices that are no longer in general use, the employer shall determine and document that the equipment is designed, maintained, inspected, tested, and operated in a safe manner. The compilation of the above described process safety information provides the basis for identifying and understanding the hazards of a process and is necessary in developing the process hazard analysis and may be necessary for complying with other provisions of PSM such as management of change and incident investigations.
PROCESS HAZARD ANALYSIS:
The process hazard analysis is a thorough, orderly, systematic approach for identifying, evaluating, and controlling the hazards of processes involving highly hazardous chemicals. The employer must perform an initial process hazard analysis (hazard evaluation) on all processes covered by this standard. The process hazard analysis methodology selected must be appropriate to the complexity of the process and must identify, evaluate, and control the hazards involved in the process. First, employers must determine and document the priority order for conducting process hazard analyses based on a rationale that includes such considerations as the extent of the process hazards, the number of potentially affected employees, the age of the process, and the operating history of the process. All process hazard analyses must be updated and revalidated, based on their completion date, at least every 5 years. The employer must use one or more of the following methods, as appropriate, to determine and evaluate the hazards of the process being analyzed:
• Hazard and operability study (HAZOP),
• Failure mode and effects analysis (FMEA),
• Fault tree analysis, or
• An appropriate equivalent methodology. Whichever method(s) are used, the process hazard analysis must address the following:
• The hazards of the process;
• The identification of any previous incident that had a potential for catastrophic consequences in the workplace;
• Engineering and administrative controls applicable to the hazards and their interrelationships, such as appropriate application of detection methodologies to provide early warning of releases. Acceptable detection methods might include process monitoring and control instrumentation with alarms, and detection hardware such as hydrocarbon sensors;
• Consequences of failure of engineering and administrative controls;
• Facility siting;
•Human factors; and
• A qualitative evaluation of a range of the possible safety and health effects on employees in the workplace if there is a failure of controls.
OSHA believes that the process hazard analysis is best performed by a team with expertise in engineering and process operations, and that the team should include at least one employee who has experience with and knowledge of the process being evaluated. Also, one member of the team must be knowledgeable in the specific analysis methods being used.
The employer must establish a system to address promptly the team’s findings and recommendations; ensure that the recommendations are resolved in a timely manner and that the resolutions are documented; document what actions are to be taken; develop a written schedule of when these actions are to be completed; complete actions as soon as possible; and communicate the actions to operating, maintenance, and other employees whose work assignments are in the process and who may be affected by the recommendations or actions.
At least every 5 years after the completion of the initial process hazard analysis, the process hazard analysis must be updated and revalidated by a team meeting the standard’s requirements to ensure that the hazard analysis is consistent with the current process.
Employers must keep on file and make available to OSHA, on request, process hazard analyses and updates or revalidation for each process covered by PSM, as well as the documented resolution of recommendations, for the life of the process.
The employer must develop and implement written operating procedures, consistent with the process safety information, that provide clear instructions for safely conducting activities involved in each covered process. OSHA believes that tasks and procedures related to the covered process must be appropriate, clear, consistent, and most importantly, well communicated to employees. The procedures must address at least the following elements: Steps for each operating phase:
• Initial startup;
• Normal operations;
• Temporary operations;
• Emergency shutdown, including the conditions under which emergency shutdown is required, and the assignment of shutdown responsibility to qualified operators to ensure that emergency shutdown is executed in a safe and timely manner;
• Emergency operations;
• Normal shutdown; and
• Startup following a turnaround, or after an emergency shutdown. Operating limits:
• Consequences of deviation, and
• Steps required to correct or avoid deviation. Safety and health considerations:
• Properties of, and hazards presented by, the chemicals used in the process;
• Precautions necessary to prevent exposure, including engineering controls, administrative controls, and personal protective equipment;
• Control measures to be taken if physical contact or airborne exposure occurs;
• Quality control for raw materials and control of hazardous chemical inventory levels; and
• Any special or unique hazards.
• Safety systems (e.g., interlocks, detection or suppression systems) and their functions.
To ensure that a ready and up-to-date reference is available, and to form a foundation for needed employee training, operating procedures must be readily accessible to employees who work in or maintain a process. The operating procedures must be reviewed as often as necessary to ensure that they reflect current operating practices, including changes in process chemicals, technology, and equipment, and facilities.
To guard against outdated or inaccurate operating procedures, the employer must certify annually that these operating procedures are current and accurate. The employer must develop and implement safe work practices to provide for the control of hazards during work activities such as lockout/tagout; confined space entry; opening process equipment or piping; and control over entrance into a facility by maintenance, contractor, laboratory, or other support personnel.
These safe work practices must apply both to employees and to contractor employees.
