Module 1: Introduction to Process Safety Management (PSM)
Learning Objectives:
•
Define Process Safety Management (PSM) and differentiate it from occupational safety.
•
Understand the historical context and motivation behind the development of PSM systems.
•
Recognize the critical importance and business benefits of effective PSM implementation.
Content:
•
What is Process Safety?
◦
Focuses on preventing and controlling incidents with the potential to release hazardous materials or energy, which can cause toxic effects, fire, or explosion, leading to serious injuries, property damage, lost production, and environmental impact.
◦
Distinction from occupational safety, which focuses on preventing injuries/illnesses to employees from tasks or work environment (e.g., slips, trips, falls).
•
Background and Evolution of PSM:
◦
Establishment of the Center for Chemical Process Safety (CCPS) in 1985 following major chemical disasters (e.g., Mexico City, Bhopal, India).
◦
Development of CCPS guidelines starting in 1989 to encourage integrated accident prevention.
◦
Influence of regulations (e.g., OSHA PSM, EPA RMP, EU Seveso Directive) and industry initiatives (e.g., ACC Responsible Care).
•
The Business Case for Process Safety:
◦
PSM systems align with business objectives, contributing to risk reduction, intellectual property management, business risk analysis, increased equipment reliability, and plant uptime.
◦
Key benefits include ensuring safety (zero incidents), improving operating efficiency, reducing costs, and maintaining competitive market position.
◦
Management commitment is vital, demonstrated through explicit actions, resource allocation, and visible leadership.
Instructional Guide for Module 1:
•
Start with a compelling story of a major chemical incident to highlight the "sense of vulnerability" and the severe consequences of PSM failures.
•
Use visual aids like "The Modified Safety Triangle" (Figure 2.1 in sources) or the "Process Risk Pyramid" to illustrate the layers of protection and the interconnectedness of safety aspects.
•
Encourage discussion on personal experiences or company-specific examples where PSM has either prevented or failed to prevent incidents.
•
Emphasize that PSM is not just a regulatory burden but a fundamental component of a profitable and sustainable business.

Process Safety Management, or PSM, is a systematic approach to preventing and controlling incidents involving hazardous materials. Unlike occupational safety which focuses on worker injuries from tasks, PSM addresses the potential for catastrophic releases of toxic chemicals, fires, and explosions that can cause serious injuries, property damage, and environmental impact.
The development of Process Safety Management was driven by tragic chemical disasters in the 1980s. The Bhopal disaster in India and the Mexico City LPG explosion both occurred in 1984, causing thousands of casualties and highlighting the need for systematic process safety approaches. In response, the Center for Chemical Process Safety was established in 1985, and comprehensive PSM guidelines were developed starting in 1989.
Welcome to our introduction to Process Safety Management, or PSM. Process Safety Management is a comprehensive approach designed to prevent catastrophic incidents involving hazardous materials. Unlike everyday workplace safety, PSM focuses on protecting entire communities and the environment from major chemical accidents that can have devastating consequences.
The development of Process Safety Management was driven by tragic historical events. In 1984, two major chemical disasters occurred: the Bhopal gas tragedy in India, where a toxic gas leak killed thousands of people, and the Mexico City gas explosion that killed over 500 people. These catastrophic events highlighted the urgent need for systematic approaches to prevent such disasters. In response, the Center for Chemical Process Safety was established in 1985, and by 1989, comprehensive guidelines were developed to encourage integrated accident prevention.
It's crucial to distinguish between Process Safety and Occupational Safety. Process Safety focuses on preventing catastrophic releases of hazardous materials that can affect entire communities and the environment, such as explosions and toxic gas releases. Occupational Safety, on the other hand, focuses on protecting individual workers from everyday workplace hazards like slips, trips, falls, and cuts. While both are important, Process Safety deals with low-frequency, high-consequence events that can have devastating impacts.
Process Safety Management is not just a regulatory burden - it's a fundamental component of a profitable and sustainable business. The business case for PSM is compelling. Key benefits include risk reduction, increased equipment reliability and plant uptime, cost reduction, and maintaining a competitive market position. PSM also ensures regulatory compliance and protects intellectual property. When properly implemented, PSM systems align with business objectives and contribute directly to profitability through improved operational efficiency and reduced incidents.
The foundation of any successful Process Safety Management program is strong management commitment. This commitment must be demonstrated through explicit actions and policies, not just words. Key demonstrations include adequate resource allocation for safety programs, visible leadership involvement in safety activities, regular safety performance reviews, and investment in training and technology. Management must also maintain zero tolerance for safety violations. Without this strong foundation of management commitment, PSM programs will fail to achieve their objectives of preventing catastrophic incidents.
