Safety Instrumented Systems - SIS Tech

SIS Tech

This training is designed to provide participants with an understanding of the relevant standards, books, and technical reports that define recognized and generally accepted good engineering practice for Safety Instrumented Systems in the Process Industry.

These requirements are presented using a lifecycle framework to provide a practical understanding of the interaction of risk management and process operability. The course materials explain how risk analysis techniques, such as layer of protection analysis (LOPA), are used to identify the need for administrative and engineered safeguards.

When risk analysis determines that a safety instrumented system (SIS) is required, the required risk reduction becomes the performance target for the SIS. IEC 61511 establishes requirements for designing and managing SISs to achieve specified safety integrity levels (SIL), which are related to order of magnitude ranges of risk reduction. Performance verification of safety instrumented functions is demonstrated using calculation techniques to determine the probability of failure on demand and spurious trip rate and using key performance indicators for feedback from field operations.

The training also presents a series of examples as workshops to illustrate the important concepts and assumptions implicit in the management of functional safety.

  • Certification Examination (after lunch)


To participate in a training/course of the TÜV Rheinland Functional Safety Training Program and to get the FS Engineer (TÜV Rheinland) certificate:

  • a minimum of 3 years experience in the field of functional safety (see below), and
  • University degree in Engineering or Equivalent engineer level responsibilities status certified by employer - is required.

(Persons who do not have the required business experience may participate in the training as well as the exam. If they pass the exam successfully the FS Engineer (TÜV Rheinland) certificate will be issued to them as soon as the necessary 3 years of business experience in the area of functional safety are achieved.)


On the foruth day of the training a half day (4 hours) examination will take place.

  • A passing score of 75% is required to qualify for the FS Engineer (TÜV Rheinland) certificate.
