• Basic interpretation of equipment markings

Section C: Certification Process

• The need for Certification
• The role of Standards
• Certification and legislative authorities globally
• Certification systems:
  • European (ATEX) System
  • International – IECEx System
  • North American System
  • UKCA
• Comparing certifications
• Documentation and technical files for certification
• Scheduled drawings VS related drawings

Question and Answers

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

This one-day course is an introduction to gas-explosive hazardous locations: what makes them hazardous, and types of hazards, 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 global certifications and their safety requirements.

This course is designed for persons who work in some capacity on equipment to be used in a hazardous location anywhere in the world (“Ex equipment”). 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, so participants can test their own understanding of the concepts presented and their application in real-life scenarios.

This is an overview course that covers the basic principles of gas-explosive hazardous locations. It covers a wide range of topics for persons with various 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.

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

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

TÜV SÜD is a leading provider of training and certification in hazardous locations (HazLoc) safety and compliance. Its programs are widely recognized in the United States and internationally. The experts at TÜV SÜD Academy possess in-depth knowledge of global standards such as IECEx, ATEX, and North American requirements, and are committed to delivering practical, application-focused training. Professionals responsible for equipment and systems in explosive atmospheres play a critical role in ensuring operational safety and compliance, and their competence is essential for the safe and efficient functioning of industrial facilities.
