How to estimate the expected performance of your barriers or controls

During the process of doing a risk analysis, there is a point where companies want to estimate the expected performance of their barriers. This is usually taken into account when doing a final risk assessment on risk matrix level, to gauge the residual risk and ALARP level. But how can you proactively perform a qualitative barrier performance assessment when there is little to no data (e.g. incidents, audits, inspections)? For some situations, a quantitative method such as LOPA can help place such a performance value on barriers. LOPA uses the [...]

I have always been mildly skeptical of risk matrices, struggling to see how [...]

Conform to ISO 31000 using the bowtie method

Many high hazard industries have to deal with the ISO 31000 standard. This is a standard for Risk Management for any organization. ISO (the International Organization for Standardization) recommends organizations to develop, implement and continuously improve a risk management framework throughout the entire organization (ISO 2009). In order to achieve this, many organizations use the bowtie method: a visualized way of doing risk assessments that enables organizations to get a good understanding of how they control risks. This blog shows you how the bowtie method will help you conform to [...]

Providing a framework for alarm management – The bowtie method

Guest blog by David Hatch from Process Safety Integrity (PSI) Don’t be alarmed – Understand the problem & undertake action The UK Health & Safety Executive highlight that there is significant evidence to show that poorly designed alarm systems have contributed to major incidents and emphasize the need to provide accurate and timely detection and diagnostics to Operators. Humans are a relatively weak protection measure and their role to prevent or mitigate hazardous events relies on an interaction with field and control room equipment to Detect (the problem), Diagnose (the [...]
