Intrinsically Safe Circuit Design

Intrinsic Safety Circuit Design

Intrinsic safety training for ‘product’ designers

Intrinsic Safety Design TrainingThis 2 day introduction to Intrinsic Safety Circuit Design course is ideal for Engineers who wish to start designing intrinsically safe equipment or brush up on their knowledge of this complicated subject and perhaps learn some new methods of achieving safety. The presenter has conducted or checked hundreds of intrinsically safe projects and has ‘real world’ experience with both design and certification of intrinsically safe equipment.

Why use us for intrinsic safety design training?

The course is run by a specialist with 25 years experience with ‘Ex’ and Intrinsic Safety Design and Certification. The presenter has completed thousands of ATEX projects including prototype design, manufacture and problem-solving. Intrinsic safety training will teach you how to design and document effectively, get certification faster and achieve more ‘flexible’ certification globally. As an ATEX/IECEx test laboratory and ATEX Certification Body, we can also demonstrate tests and verification methods, a unique feature of this course. ExVeritas uses an electronic cloud-based e-learning system called ‘Learn Ex,’ once registered candidates can have immediate access to course notes which are updated electronically.  Simply visit for further details about the benefits of LearnEx.

”This is a great course and unique of its kind. I can recommend this course to every designer.”  John K. O.  Pedersen, Senior RF Engineer, Motorola Solutions. ”The lecturer was extremely knowledgeable with over 25 years of experience in the industry, and the subject matter was immediately applicable to my project.”  James Wightman, Principal Electrical Engineer  PMP

Course Developer:

Diego Oliveira Diego is a degreed engineer with over 11 years’ experience with the design and certification of Hazardous Location equipment.  He has worked for manufactures, laboratories, and certification bodies in this industry.  Diego brings the experience gained from more than 100 Intrinsically Safe projects ranging in application and complexity.  As a member of a Certification Body with design experience and current practitioner in this field, you can be assured that the content is relevant and applied with a practical bias.

Intrinsic Safety Training Course Syllabus

Intrinsic safety design training for designers and certification engineers Day 1

  • Introduction and Overview of Competence Requirements
  • Deriving the required level of safety (area classification, EPL) for i.a, i.b. and i.c.
  • Explosion Properties and Terminology required for intrinsic safety
  • Intrinsically Safe ‘Certification’ and Certification Schemes (ATEX, IECEx, NEC500 & 505)
  • Intrinsic safety overview. (A complete overview of the entire subject and how it all ‘works together’ before moving on to the detail with ‘i.c.’ specific issues and relaxations)
  • Intrinsically Safe Systems Overview (cables, barriers and earthing)

Day 2

  • Power Supply Assessment (Calculations, matched power, batteries including test demonstration)
  • Energy storage (assessment of capacitance and inductance, methods of reducing energy or permitting more energy, design methods, tricks and tips used by experts, spark testing)
  • Use of safety components (zener shunt, diodes for blocking and inductance control, resistors with capacitance) and safety component rating and de-rating (zeners).
  • Separation & Segregation (Creepgage, clearance, tracks, encapsulation, CTI)
  • Thermal Assessment (small component rules, thermal calculations, potting, testing)
