Study Notes

Overview of Risk Assessment and Management

The module covers risk assessment and management.
Upon completion, learners should be able to define risk management, differentiate between risk, hazard, energy sources, probability, and consequence, describe the risk assessment team and process, identify risk assessment tools, define components of a risk management strategy and plan, and communicate details of the plan.

Key Terms

Hazard: A source of potential harm that exists when a source of energy could be released.
Risk: Risk has two components, probability (or likelihood) of an event and its consequences.
Risk Matrix: A mechanism for assessing the level of risk using probability and consequence, and categorizing risk as high, medium or low.
Hierarchy of Controls: A ranking of the ways to manage risk from most to least effective.

Risk Assessment Team

A risk assessment team is typically comprised of a facilitator, safety representative, subject matter expert, engineer, operator, supervisor, and/or manager.
The quality of the assessment relies on the collective knowledge and experience of the team.

Team Resources

The team utilizes various sources, such as operating procedures, training manuals, compliance audits, incident investigations, pre-start up safety reviews, management of change, and process safety information.

Establishing Context and Scope

Context refers to the circumstances of the risk assessment (e.g., new plant design vs. incident investigation).
Scope outlines the specifics of the assessment, such as the physical location or topics. This helps define the boundaries and ensures goals are met.

Risk Management Process

The process involves system definition, risk assessment, risk analysis (hazard identification, consequence analysis, risk estimation, risk acceptability), and stakeholder participation.

Examples Demonstrating Poor Risk Management

Quebec Bridge Collapse: An example of poor design and load calculation leading to a fatal collapse.
Chilean Mine Cave-In (2010): The disaster resulted from unstable conditions and lack of proper safety measures.
Unsecured Truck Load: An unsecured load shifted during transport, causing injury to a worker.

Risk Assessment Tools

Checklist: A straightforward method designed to evaluate hazards by comparing them against predefined criteria. It is particularly effective when utilized by a trained individual or a small, focused group. However, while it provides a systematic approach to identifying potential risks, this method does not delve deeply into the underlying factors contributing to those hazards, limiting its value in yielding profound insights into risk management strategies and solutions.
Qualitative Risk Matrix (QRM): This analytical tool is instrumental in assessing both the probability and the potential consequences of various risks. It supports organizations in determining the severity of identified risks, enabling them to prioritize which hazards require further attention. By categorizing risks into various levels based on their likelihood and impact, QRM allows decision-makers to allocate resources effectively and develop appropriate risk mitigation strategies.
Failure Modes, Effects & Analysis (FMEA): This is a structured five-step methodology aimed at uncovering potential hardware failures within a system. The steps typically include identifying failure modes, assessing their impacts, and determining their causes. By systematically analyzing potential failures, organizations can proactively address weaknesses in design and operational processes, ultimately enhancing reliability and safety in their systems.
Hazard & Operability Analysis (HAZOP): HAZOP is a sophisticated method used to scrutinize system operations meticulously. It focuses on pinpointing possible failure points by examining deviations from normal processes during brainstorming sessions. This structured hazard review facilitates comprehensive discussions among team members, helping to identify vulnerabilities that could compromise the safety and performance of a system, thereby informing effective improvements or interventions.
Fault Tree Logic (FTL): This analytical approach is employed to trace an incident methodically back to its root causes. FTL utilizes a visual diagram to represent the logical relationships between various failures that contribute to an undesirable event. By identifying initial failures that instigate a problem, organizations can apply corrective measures that address the fundamental issues rather than merely treating the symptoms of a failure.
Bowtie Analysis: This advanced risk assessment method integrates elements of both preventive and mitigative measures, offering a framework for organizations to manage risks effectively. Bowtie analysis begins with the identification of hazards, followed by detailing the threats that could potentially exploit these hazards and lead to adverse outcomes. The framework not only emphasizes consequences but also highlights recovery measures, enabling organizations to develop a comprehensive risk response strategy.

Risk Equation

Risk = Probability of Occurrence * Consequence Severity

Hierarchy of Controls

Elimination: Removing the hazard completely.
Substitution: Replacing a hazardous material or process with a safer alternative.
Engineering Controls: Equipment or systems to reduce risk.
Administrative Controls: Procedures to limit exposure to hazards.
Personal Protective Equipment (PPE): Used as a last resort when other controls are not feasible.

Risk Management Strategies

Recovery and Control Measures: Actions to minimize incident probability and consequences. Includes first aid, signage, and safety training.
Communication and Consultation: Critical for effective risk management, involves sharing information with all stakeholders throughout the risk management project.
