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. The course discusses how to quantify hazardous event likelihood using a range of techniques, in order to assess whether the level of risk is sufficiently low and, if not, where to focus attention for cost-effective improvement. It also considers instrumented protective systems and other risk reduction measures, and assesses their actual benefit.
- international standards - IEC 61508/61511
- risk and criteria
- risk assessment
- consequence assessment
- Layer of Protection Analysis (LOPA)
- event tree analysis
- reliability concepts of elements and states
- guided exercise - development of fault trees to assess hazards
- use and collection of reliability data
- trip system overview

You should be able to demonstrate a working knowledge of SIL and hazard assessment including:
logical analysis using fault tree techniques for 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
dasic human error assessment
- applying basic SIL and hazard assessment in a variety of situations to help in making more effective cost and effective decisions.
