Course Description
The Bowtie Risk Assessment Model is a powerful tool used to assess specific events or scenarios by visually mapping potential hazards, causes, preventive and mitigative controls, and consequences. As outlined in ASSP TR-31010, Bowtie analysis enables decision-makers to understand and communicate risk in a simplified and structured format, making it an essential method across industries.
This interactive course introduces participants to the concept of Bowtie analysis and its application in risk identification, assessment, and communication. Participants will explore the use of singular risk assessment methods (e.g., JHA, FMEA, LOPA, JRA) and how these can integrate into a Bowtie framework. The course includes real-world case studies, hands-on exercises, and exposure to advanced Bowtie applications such as Striped and Cascading Bowtie Models.
You can earn the Risk Management Certificate by completing the three core courses in the program. By adding the Bowtie Risk Assessment course, you’ll qualify for the Advanced Risk Management Certificate. To maximize the value for both you and your organization, we recommend pursuing the Advanced Risk Management Certificate. This course is ideal for Environmental, Health, and Safety (EHS) professionals, risk analysts, and operational leaders seeking a structured and practical approach to enhance their risk assessment capabilities using the Bowtie method.
What You Will Learn
- Define and distinguish between prevention and mitigation within the Bowtie model.
- Compare and evaluate singular risk assessment methods and their integration with Bowtie analysis.
- Apply the Semi-Quantitative Bowtie method to assess complex, real-world scenarios.
- Recognize the limitations of traditional Bowtie analysis and identify when advanced methods are needed.
- Interpret and utilize Quantitative Bowtie Risk Assessment techniques for high-risk operations.
- Demonstrate the use of Striped and Cascading Bowtie Models across industry-specific applications.
