(147c) Adapting Cause and Effects Methodology to Your Safety Instrumente System (SIS) to Reduce Human Errors from Engineering, Operations and Beyond
- Conference: AIChE Spring Meeting and Global Congress on Process Safety
- Year: 2017
- Proceeding: 2017 Spring Meeting and 13th Global Congress on Process Safety
- Group: Global Congress on Process Safety
- Time: Wednesday, March 29, 2017 - 9:00am-9:30am
A Safety Instrumented System (SIS) is designed to reduce the likelihood of hazardous risk by decreasing the frequency of unwanted accidents. The amount of risk reduction that an SIS can provide is represented by its safety integrity level (SIL). The SIS is designed to detect when the process reaches a hazardous condition and respond accordingly to move the process to a safe, thus preventing the unwanted accident from occurring. Studies indicate however, that over 50% of all SIS failures are related to human error. While many SIS systems boast having SIL 3 certification, itâs often the human interactions that render many of these well intended systems to be essentially non-existent. A cause and effects methodology is an approach many in the industry are exploring to help reduce human errors throughout the entire safety lifecycle of the SIS.
What attendees will learn
In this session attendees will learn how a safety interlock matrix can help reduce human errors during key phases of the lifecycle:
Provide intuitive cause and effect diagrams for input in the Safety Requirement Specification (SRS)
Reduce translation errors during the design and engineering phase
Help to validate the SIS during installation and commissioning
Maintain system integrity during operation and maintenance
Provide traceability for changes after commissioning
