In high-hazard industries like oil and gas, mining, and petrochemicals, traditional risk assessment matrices and massive spreadsheets often fail to communicate the real picture. When safety critical information is buried in paperwork, workers and management lose sight of the actual risks.
Enter the Bowtie Analysis Methodology.
The Bowtie method is an internationally recognized, highly visual risk assessment tool that paints a clear picture of complex risk scenarios. At iSTEC Training, our comprehensive Bowtie Analysis Course equips safety professionals, engineers, and management teams with the skills to map out hazards, identify critical barriers, and prevent catastrophic events.
A Bowtie Analysis is a visual risk assessment methodology that maps out a pathway from the causes of an event to its consequences. Shaped like a men's bowtie, the diagram centers around a "Top Event" (the moment control over a hazard is lost) and clearly illustrates:
The Hazard: The dangerous operation or material (e.g., highly flammable liquid).
Threats (Left Side): The root causes that could trigger the Top Event.
Consequences (Right Side): The severe outcomes if the Top Event occurs (e.g., explosion, toxic release, fatalities).
Preventative Barriers: The controls in place to stop the Threat from causing the Top Event.
Mitigative Barriers: The controls in place to minimize the Consequences if the Top Event happens.
Escalation Factors: Conditions that could cause a barrier to fail (and how to manage them).
Organizations worldwide are adopting the Bowtie method as a core pillar of their Process Safety Management (PSM) and Operational Risk frameworks. The benefits of transitioning to Bowtie include:
Crystal Clear Communication: It transforms complex engineering and safety data into a simple, highly visual diagram that everyone—from boardroom executives to frontline operators—can easily understand.
Focus on Critical Controls: It highlights the exact safety barriers (both human and mechanical) that are keeping your facility safe, ensuring they are prioritized during maintenance and audits.
Identifies Vulnerabilities: The method clearly exposes "single points of failure" and missing safeguards that traditional risk matrices often overlook.
Proves ALARP: It visually demonstrates to regulators and stakeholders that your risks are reduced to As Low As Reasonably Practicable (ALARP).
Our expert-led training goes far beyond theory. Through practical workshops and real-world case studies relevant to South African and global heavy industries, delegates will learn how to:
Understand the foundational principles of risk and barrier management.
Correctly identify Hazards, Top Events, Threats, and Consequences.
Facilitate and lead an effective Bowtie workshop with a multidisciplinary team.
Map and link Preventative and Mitigative Safety Critical Elements (SCEs).
Identify escalation factors and implement secondary controls.
Integrate Bowtie diagrams into your existing Safety Management System (SMS) and Incident Investigation processes.
This training is essential for professionals responsible for operational risk and process safety, including:
Risk and Safety Managers (SHERQ / HSE)
Process Safety Engineers and Operations Managers
Maintenance and Reliability Engineers
Incident Investigators and Auditors
Supervisors in high-risk sectors (Mining, Aviation, Petrochemical, Manufacturing)
Stop hiding your safety critical controls in unreadable spreadsheets. Empower your team to visualize, communicate, and manage catastrophic risks effectively with iSTEC's globally trusted training programs.
