Safety Instrumented Systems
EFSTAS (formerly ProSalus Ltd.) is an accepted course provider of the TÜV Rheinland Functional Safety Program for Safety Instrumented Systems trainings. The TÜV Rheinland Functional Safety Training program is a unique opportunity to provide certified evidence of competency in functional safety from an internationally recognised organisation.
The FS Engineer demonstrates competency in the fundamentals of Functional Safety and provides a skill set that is transferable from one work situation to another and enables staff to fulfill responsibilities and to perform activities to recognised standards of competence on a regular basis, in order to
- reduce risks
- satisfy legal and regulatory requirements
- meet the organisation’s business objectives
- enable the organisation to meet contractual commitments.
- The principles and concepts of the internationally agreed standards IEC 61508 and IEC 61511 for safety instrumented systems (SIS)
- Hazard identification and the hazard and operability (HAZOP) process including understanding cause / consequence pairs and the sequence of events leading to the hazard.
- Risk, the setting of tolerable risk targets for safety, asset and the environment and methods to achieve these targets by reducing risks to as low as reasonably possible (ALARP).
- The concepts and differences between qualitative, semi quantitative and quantitative risk assessment methods and when and how to apply them.
- The principles of risk modelling, event tree analysis (ETA) and fault tree analysis (FTA) and how to model protective systems using these techniques.
- How to set up, use and apply the most popular safety integrity level (SIL) risk assessment methods such as risk graphs, risk matrices and layers of protection analysis (LOPA).
- SIL determination for preventative and mitigation systems including fire and gas systems (e.g.detector coverage and mitigation capability).
- Correctly developing the Safety Requirements Specification (SRS) to ensure the requirements are auditable, testable and written for ease of understanding.
- How to design safety-instrumented systems for protecting against process related hazards using the techniques and measures in IEC 61508 and IEC 61511 including developing life cycle procedures (e.g. maintenance, inspection and testing).
- The technical information required on all system components including extracting reliability data for the application from manufacturers certificates, reports and applying confidence levels to the data.
- SIL demonstration calculations such as probability of failure on demand (PFD), safe failure fractions, hardware fault tolerance and proof test interval determination.
- How to identify and calculate the impact of common cause failures (Beta factor) on the reliability of protective systems.
- Requirements for proven in use evidence for existing installed equipment.
- Requirements for validation documentation to demonstrate that systems, (including application software and software and hardware integration) have been fully tested checked and approved against the safety requirements specification.
- Introduction to the latest software tools for risk assessment and designing safety instrumented systems and integrating them with other protective technologies.
Instrument engineers, Process engineers and Safety engineers as well as Operating and Maintenance personnel who are involved in any of the safety lifecycle phases for safety instrumented systems from hazard and risk assessment, shut down system/fire and gas systems design to testing maintenance.
In accordance with the TÜV Rheinland Functional Safety Training Program:
- A minimum of 3 to 5 years experience in the field of functional safety.
- University degree or equivalent engineering experience and responsibilities as certified by employer or engineering institution.
A four (4) hour two part competency examination compromising:
- Part 1 = 60 multiple-choice questions (1 mark each question)
- Part 2 = 10 multiple part questions (4 marks each question)
The pass score criterion is 75%.
