DEKRA ATEX & DSEAR IChemE Accrediated Course

Our 4-day flagship IChemE Accredited Course

Implementing process safety programmes requires specialised skills and competencies backed-up by technical and management proficiency.

ATEX & DSEAR Training

Whether you are carrying out a process safety review, implementing safety audits or ensuring compliance with standards and regulations, DEKRA has the up-to-date training backed by resources and skills to complete this task.

The flagship IChemE accredited four-day course from DEKRA Process Safety, Practical Aspects of ATEX / DSEAR Compliance Success, will take delegates through the most important technical aspects of understanding and managing the risks of industrial explosions. Delegates will learn about the legal requirements as outlines by the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) and ATEX Worker Protection Directive. The specific areas that will be covered are:

  • Hazardous Area Classification (i.e., Zoning) for gases, vapours and dusts and strategies for controlling and preventing hazardous flammable atmospheres.
  • Ignition Assessment, which will entail detailed discussion on equipment selection, static electricity and non-electrical mechanical equipment.
  • Fire and explosion hazards and severity assessment. We will help you appreciate the most common and different types and industrial fires and explosion. This will also entail practical and accessible tools for assessing the severity of fires and explosions.
  • Explosion protection systems such as explosion venting, suppression and containment systems. This section will cover the scope of applicability, pros and cons of each protection method.
  • DSEAR Risk Assessment. By this point, all the various areas discussed above will be logically integrated, and practical guidance on carrying out a ‘suitable and sufficient’ DSEAR risk assessment will be given.

The course is jam-packed with practical examples, demonstration, and videos with well-designed slides and written-out course notes for personal reading. The course will be delivered with effective teaching methods and seeks to create an informative and enjoyable experience for delegates.

The course can be booked as a complete four day package, or as individual/multiple days dependent on personal requirements.

Who will benefit?

Engineers and engineering managers (and those with similar responsibilities) from companies storing, handling, using or processing flammable liquids, gases and/or powders, including those materials generated as waste streams (e.g. flammable dust collected in a filter). Many operators and senior managers have also benefited from attending this course.

The course covers:

What our delegates say:

"Depth of knowledge obvious and all questions were answered fully. Also trainers were able to relate back to the workplace due to their experience in investigations/audits."

"Course content was well suited to the audience and to the reason for running the course. Questions at the end of the section are invaluable."
