Explore process safety management and engineering, covering risk analysis, hazard management, mechanical integrity, management of change, incident investigation, and emergency planning under health, safety, and environment systems.
Explore how management of change drives safe operations through formal documentation, hazard and risk analysis, and competent sign-off, using historical lessons from Flixborough to improve process safety leadership.
This lecture covers key process safety risk tools, including the Swiss cheese barrier model, bow tie diagrams, Hazop and FMEA, event tree and what-if analyses, and asset integrity concepts.
Explore permit to work, risk assessment, and isolation controls within a safe system of work, addressing interfaces with adjacent plants and contractors and safe shift handover.
Identify how thermal runaway occurs due to design flaws and control failures, and learn to apply safe operating envelopes, overfill prevention, and bulk storage safety measures.
Explore fire and dust explosion hazards, detection and suppression strategies, and how to design and practice on-site and off-site emergency preparedness plans for process safety management.
Process safety management (PSM) is a management system that focuses on preventing, preparing for, and responding to catastrophic releases of chemicals or energy from a process plant.
PSM can be implemented using the established OSHA scheme or others made available by the EPA, AIChE's Center for Chemical Process Safety, or the Energy Institute.
The purpose of PSM is to maintain the safety of a production plant. It addresses the safety measures required to prevent accidental release of hazardous material from its containment, like a vessel, tank, piping or pipeline.
The PSM standard lists 14 process safety elements that employers must meet:
Process Safety Information
Process Hazard Analysis
Operating Procedure
Employee Participation
Process Safety Management Training
Contractor Training
Pre-Startup Safety Review
Mechanical Integrity
Hot Work Permits
PSM guidelines for compliance include:
Proactive identification
Evaluation
Mitigation or prevention of chemical releases
Process Safety: A Symbiotic Dance between Management and Engineering
Process safety is a critical discipline focused on preventing major accidents involving hazardous materials or processes. It's a collaborative effort between engineering expertise and management systems.
Engineering safeguards:
Hazard Identification: Engineers meticulously analyze processes to pinpoint potential hazards like leaks, explosions, or fires.
Control Measures: Equipment design incorporates safety features like pressure relief valves, firewalls, and robust containment structures.
Automation: Implementing automated systems like emergency shutdowns minimizes human error and expedites response during emergencies.
Management ensures these safeguards are effectively utilized:
Policies & Procedures: Clear guidelines are established for safe operation, maintenance, and handling of hazardous materials.
Training & Awareness: Employees receive comprehensive training on process risks, safety protocols, and emergency response procedures.
Incident Investigation: Accidents and near misses are thoroughly investigated to identify root causes and prevent similar occurrences.
Continuous Improvement: The process safety program undergoes regular audits and revisions to adapt to evolving regulations and best practices.
This synergy between engineering controls and management practices fosters a robust safety culture. By proactively identifying hazards, implementing safeguards, and fostering employee awareness, process safety management and engineering work in tandem to prevent incidents and create a safer work environment.
