PSSR for Safety | Pre-Startup Safety Review (PSSR) | Download PPT

The industrial landscape is fraught with potential risks and hazards, especially during startup processes. To mitigate these risks effectively, industries employ a robust safety protocol known as Pre-Startup Safety Review (PSSR). This article delves into the intricacies of PSSR, exploring its significance, key components, benefits, challenges, and its role across different industries.

Understanding PSSR

Definition and Purpose

PSSR, or Pre-Startup Safety Review, is a systematic process that evaluates the safety aspects of a new or modified facility before it becomes operational. The primary purpose is to ensure that the startup process is executed safely, minimizing the risk of accidents or incidents.

Regulatory Requirements and Standards

Various regulatory bodies and industry standards mandate the implementation of PSSR to guarantee compliance with safety regulations. These standards outline the specific steps and requirements for a thorough safety review.

Key Components of PSSR

Equipment Inspection and Verification

One of the fundamental aspects of PSSR is the inspection and verification of all equipment involved in the startup process. This includes ensuring that equipment is installed correctly, calibrated properly, and meets safety standards.

Process Hazard Analysis

PSSR involves a comprehensive analysis of potential hazards associated with the startup process. Identifying and mitigating these hazards is crucial for preventing accidents during the initial stages of operation.

Safety Instrumented Systems (SIS)

The evaluation and verification of safety instrumented systems play a pivotal role in PSSR. These systems are designed to respond to potential safety hazards, providing an additional layer of protection.

Personnel Training and Readiness

Ensuring that personnel involved in the startup process are adequately trained and prepared is a critical component of PSSR. This includes emergency response training and familiarization with safety protocols.

Benefits of Implementing PSSR

Prevention of Accidents and Incidents

By conducting a thorough safety review before startup, PSSR significantly reduces the likelihood of accidents or incidents during the initial phases of operation.

Compliance with Safety Regulations

Adherence to safety regulations is not only a legal requirement but also a fundamental aspect of responsible and sustainable business practices. PSSR ensures compliance with these regulations.

Increased Operational Reliability

Implementing PSSR enhances the overall reliability of operations. By identifying and addressing potential issues beforehand, the likelihood of operational disruptions is minimized.

PSSR Process Steps

Planning and Scheduling

Proper planning and scheduling are essential for the successful execution of PSSR. This involves coordinating various activities and allocating resources efficiently.

Documentation Review

A meticulous review of documentation, including design specifications, safety procedures, and equipment manuals, is conducted to ensure that everything is in order.

Physical Inspection and Testing

Inspecting the physical aspects of the facility and conducting necessary tests are integral steps in PSSR. This includes checking equipment functionality and safety systems.

Verification of Safety Systems

Ensuring the effectiveness of safety systems, such as emergency shutdown procedures and alarms, is crucial for a successful PSSR.

Common Challenges in PSSR

Lack of Awareness

One of the challenges in implementing PSSR is the lack of awareness about its importance. Educating personnel about the significance of PSSR is crucial for successful implementation.

Inadequate Training

Insufficient training of personnel involved in the PSSR process can lead to oversights and gaps in safety protocols. Continuous training and skill development are essential.

Insufficient Documentation

Incomplete or inaccurate documentation poses a significant challenge in PSSR. Thorough and accurate documentation is vital for a successful safety review.

Best Practices for Effective PSSR

Involvement of Experienced Personnel

Having experienced and knowledgeable personnel involved in the PSSR process is crucial for a comprehensive and effective safety review.

Continuous Improvement and Feedback Loops

PSSR is an ongoing process that benefits from continuous improvement. Establishing feedback loops ensures that lessons learned are incorporated into future safety reviews.

Regular Updates and Reviews

As technology and safety standards evolve, it’s essential to regularly update and review PSSR processes to stay current and effective.

PSSR in Different Industries

Application of PSSR in Manufacturing

Manufacturing facilities benefit from PSSR by ensuring the safety of complex processes and machinery during startup.

PSSR in the Oil and Gas Industry

In the oil and gas industry, PSSR is crucial for preventing catastrophic events and ensuring the safety of both personnel and the environment.

PSSR in Pharmaceuticals

Pharmaceutical companies rely on PSSR to guarantee the safety of processes involved in drug manufacturing.

PSSR stands for "Pre-Startup Safety Review." It is a crucial phase in the life cycle of a process or facility, especially in industries where safety is a top priority, such as chemical, petrochemical, and manufacturing plants. The purpose of a PSSR is to ensure that a new or modified process is ready to be started up safely and efficiently.
During a PSSR, a multidisciplinary team reviews and verifies the design, construction, and installation of the process or facility to identify and address potential safety hazards before startup. This helps prevent accidents, injuries, and damage to equipment.
Here's a sample example of a PSSR checklist for a new chemical manufacturing process:

Documentation Review:

Verify that all design documents, including P&IDs (Process and Instrumentation Diagrams), equipment specifications, and operating procedures, are complete and up-to-date.

Equipment Inspection:

Inspect all process equipment to ensure it is installed correctly and meets safety standards.

Check that safety devices such as relief valves, emergency shutdown systems, and alarms are in place and functional.

Training and Competency:

Confirm that operators and maintenance personnel are adequately trained on the new process.

Ensure that personnel are aware of emergency procedures and know how to respond to potential hazards.

Hazard Identification:

Conduct a thorough hazard analysis to identify and assess potential risks associated with the new process.

Implement necessary control measures to mitigate identified hazards.

Mechanical Integrity:

Verify the mechanical integrity of critical equipment, including piping, vessels, and instrumentation.

Ensure that all equipment is properly installed, aligned, and tested.

Operational Readiness:

Confirm that utilities, such as power, water, and steam, are available and meet the process requirements.

Check that necessary raw materials and chemicals are on-site and in compliance with specifications.

Emergency Response Planning:

Review and update the emergency response plan.

Conduct drills to ensure that personnel are familiar with emergency procedures and evacuation routes.

Regulatory Compliance:

Ensure that the new process complies with all relevant local, national, and international regulations and standards.

By systematically addressing these aspects and more, a PSSR helps ensure that a new or modified process can be operated safely and efficiently from the moment it is started up. This proactive approach significantly reduces the risk of incidents and enhances overall workplace safety.


In conclusion, Pre-Startup Safety Review (PSSR) stands as a crucial pillar in ensuring the safety and reliability of industrial startup processes. By meticulously examining equipment, processes, and personnel readiness, PSSR serves as a proactive measure against potential hazards. As industries evolve, the importance of PSSR remains steadfast, contributing to a safer and more responsible industrial landscape.
