Self-Administered Test: Application of terms, definitions, and concepts; Case Study that incorporates topics covered in this course

This one-day course is focused on the proper installation of an IS system. It begins with an overview of the intrinsic safety protection technique, the advantages and disadvantages of this method and how intrinsic safety helps protect circuits in hazardous locations. This course helps participants to select safety barriers for a given design, as well as how to verify, inspect and maintain an IS system. Emphasis is on learning the fundamentals, in order to promote compliance with safety requirements, given the hazardous nature of the environment.

This course covers the knowledge required to select a certified safety barrier for a given application and how to connect it to IS field devices. It is focused specifically on the proper installation of an intrinsically safe system, which is critical to its effectiveness.

Instructor-led training in a virtual classroom. This means the course is Live Online. Participants will learn through online teaching. Lectures, case studies, group exercises, discussions, problem solving, examples with explanation, assignments and/or quizzes happen in the virtual classroom training. Delivery provides a blend of theoretical knowledge and real-life examples of theory at work when designing an intrinsically safe system. Case studies are used to encourage application-oriented thinking to hazardous environments. Participants need to connect to the class from any internet accessible location. Each module is delivered live using webinar technology, creating a virtual classroom learning environment. Live sessions provide you with direct access to the trainer so you can ask questions, understand complex concepts and share ideas with peers. Webcam and microphone are REQUIRED to interact with the instructor and/or other participants.

The course content and structure are designed by the domain experts from TÜV SÜD.

With immense experience and knowledge in the relevant standards, our team of product specialists and technical experts at TÜV SÜD, developed the course content based on current business landscape and market requirements.

A self-administered test that tests theoretical knowledge as well as the ability to apply it to case scenarios.

Access to Standards and codes is helpful but not mandatory. A calculator is required.
