Activities focused on reducing the negative impact of risk by taking appropriate actions are determined on the basis of a risk analysis. It is mainly used in the context of occupational health and safety - in the preparation of safety management systems and safety policy.
Risk analysis allows you to identify, assess and control the level of risk both quantitatively and qualitatively.
Risk analysis methodologies
When analyzing risk, various methodologies are used - the most popular of them is HAZOP (Hazard and Operability Studies), or the analysis of threats and operational capabilities.
These methodologies are selected depending on what the examined entity is and what activities it concerns.
HAZOP analysis
The HAZOP (Hazard and Operability Studies) methodology uses the PN-IEC 61882 standard. It is mainly used when designing new installations, processes and facilities, as well as for their modernization.
This analysis is aimed at considering the connections between individual elements of the area under consideration and determining whether there are deviations from the design assumptions in terms of safety. Then, the causes are identified and the risks associated with deviations are determined.
Other methods of risk analysis:
- FTA - Fault Tree Analysis
- QRA - Quantitative Risk Assessment
- PHA - Initial Hazard Analysis
- LOPA - analysis of security layers
- FMEA - analysis of the types and effects of possible errors
- ETA - event tree analysis
Risk analyzes are carried out by people with appropriate background in this field.
