Advanced Hazard Assessment Techniques for SIL Determination

This event has been cancelled. If you have any questions, please contact the event planner directly.

(previously titled 'SIL Determination & Hazard Assessment')


Management of risk and the demonstration of appropriate risk reduction measures are becoming increasingly important in industry today. This can be relevant to compliance with aspects of legislation, such as COMAH, and in the application of standards such as IEC61508 and IEC61511.


This course is designed for those who need to understand the causes and sequence of failure that can lead to significant hazardous events occurring and be able to identify the key contributors to the level of risk - to people, business or the environment. 

Topics include:
- Calculation of hazardous event frequencies
- Assessment of risk reduction from protective systems and Safety Integrity Levels (SIL)
- Criteria for tolerable levels of risk
- Assessment of demand frequency on protective systems

Duration: 5 days 

The benefits
The effective use of the techniques allows questions to be answered in the areas of safety, health and environment; asset management and maintenance; loss prevention; new investment.

The course
On completion of the course you should be able to demonstrate a working knowledge of SIL and hazard assessment including:

- Logical analysis, using fault tree techniques of scenarios leading to hazardous events
- Use of data and its application to predict the likelihood of a hazardous event
- Development of practical hazard criteria
- Handling of dependent or common mode failures
- Basic human error assessment
- Applying basic SIL and hazard assessment in a variety of situations to help in making more effective and cost effective decisions

This course is also suitable as a basic qualification for those wanting to become hazard and reliability analysts.
