TUV FS Engineer SIS

TÜV Rheinland Functional Safety Program
Functional Safety Engineer Certification

The TÜV Rheinland Functional Safety Program is a unique opportunity to provide evidence
of competency in functional safety from an internationally recognized organisation
The certified FS Engineer (TÜV Rheinland) certificate 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 recognized 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.
By understanding:
• 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 lifecycle 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
Course Objectives
Jørgen Nielsen, a recognised expert in functional safety and a member of the international
IEC 61511 committee, leads the course. The course will equip participants with the
knowledge for understanding and mastering the application, principles and requirements
of IEC 61508 – Functional safety of electrical/electronic/programmable electronic safety
systems and IEC 61511 – Functional Safety: Safety Instrumented Systems for the Process
Sector.
Successful participants, who also have sufficient functional safety experience, will achieve
the prestigious FS Engineer (TÜV Rheinland) SIS certification.
The course will provide three days of classroom tuition and practical guidance, mixed with
practical exercises based on real life examples. Day 4 consists of a four-hour two-part
proficiency examination with:
Part 1 = 60 multiple-choice questions
Part 2 = 10 multiple part questions

Day 1 Agenda
Will provide an introduction to the functional safety standards, the underpinning legislation
and the concept of the functional safety lifecycle. Phases 1, 2, 3, 10 and 11 - process hazard
analysis, risk assessment, allocation of safety functions and functional safety and
competency management will be discussed in depth and participants will be introduced to
the concepts of the international standards that cover this area of risk assessment and risk
reduction.
The topics covered are:

• IEC 61508 and IEC 61511 background
• Functional Safety Management and the application of the FS lifecycle
• Competency Management and Assessment
• Hazards, Risk and ALARP principles
• Risk Reduction
• SIL Determination by Risk Model
• Event Tree Analysis
• SIL Determination using Event Tree Analysis
• Fault Tree Analysis (FTA)
• SIL Determination using Fault Tree Analysis
• Quantified Risk Assessment
• Practical Exercises
• Case Studies with typical findings and issues
• Exam Preparation exercise
Day 2 Agenda
Covers phases 3 and 4 in depth from determining the target SIL, developing the Safety
Requirements Specification (SRS) and how to undertake appropriate cost effective designs
for Safety Instrumented Functions (SIF). Participants will be introduced to the concepts of
Probability of Failure on Demand (PFD), safe failure fraction, hardware fault tolerance,
proven in use, failure modes, reliability, diversity, separation and the influence of common
cause.
• Risk Graph Calibration
• SIL Determination by risk graphs qualitative & Semi Quantitative
• SIL Determination Exercises
• Layers Of Protection Analysis (LOPA)
• SIL determination using LOPA
• LOPA Exercise

Day 3 Agenda
Covers phase 4 - application software requirements for safety-instrumented systems (SIS)
and the relationships between hardware and software architecture. In depth instruction in
phase 9 requirements for verification explaining methods for calculating the Probability of
Failure on Demand (PFD), safe failure fraction and hardware fault tolerance, the concepts
of failure modes, reliability and the influence of common cause failures will also be covered
in more depth.
