Self-Administered Day Three Test: Terms, Definitions, Interpretations and Concepts; Case Study

This is a three-day overview course designed for persons who work in some capacity on equipment to be used in a hazardous location anywhere in the world (“Ex equipment”): from design to certification to installation, operation, maintenance, and inspection. It is intended for persons with little or no knowledge of and experience with hazardous locations. A self-administered multiple-choice test is provided at the end of each day, so participants can test their own understanding of the concepts presented and their application in real-life scenarios. Emphasis is on learning the fundamentals, in order to promote compliance with safety requirements, given the hazardous nature of the environment.

Day 1 of this course is an introduction to hazardous locations: what makes them hazardous, especially given electrical and non-electrical devices located within them or nearby that can become a source of ignition. The classification systems used worldwide to define the nature of the hazard are covered, as well as the global certifications and their safety requirements.

Day 2 provides an overview of protection approaches used in product design, as well as details about some specific protection methods for electrical and non-electrical equipment for use in gas-explosive atmospheres.

Day 3 covers more protection techniques, as well as an overview of the installation, monitoring, maintenance, and inspection of electrical equipment intended for use in hazardous locations in order to assess and control risks.

This is a foundation course that covers a wide range of topics for persons with a variety of backgrounds who work with equipment in potentially hazardous environments.

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 activities that involve real-life examples of theory at work in the hazardous location (HazLoc) industry. Case studies will be used to encourage application-oriented thinking. 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.

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

Having access to Standards and codes is helpful but not mandatory.
