Hydrogen emerges as a promising alternative to fossil fuels to decarbonise industrial sectors including aviation. However, the storage, transfer, and combustion of hydrogen require special care because of its highly explosive nature when mixed with air (oxygen).

Explosion protection guidelines establish how to operate safely in hazardous environments, such as hydrogen factories and storage facilities. Accordingly, explosion hazardous areas are formed based on careful considerations.

This course covers explosion protection principles and explains the standards used to determine the size of hazardous area zones used to minimise the risk of potentially fatal accidents. Emphasis will be placed on challenges associated with explosive materials such as hydrogen, including leakage detection and propagation modelling.

Expert facilitators will demonstrate the application of explosion protection principles through selected, industrially relevant case studies. 

Opportunities will be provided to consult with professionals with global industrial experience in explosion safety.

Course structure

Lectures are supplemented by hands on tutorials covering hydrogen explosion modelling and leakage detection based on computational simulations and machine vision, respectively. All delegates will receive a Certificate of Attendance at the end of the course.

What you will learn

On completion of the course, you will be able to:

  • Recognise some operating conditions that impose risks of explosive mixture formation and ignition.
  • Describe the key ideas behind the engineering principles of explosion protection.
  • Identify modern tools applied to estimate the risk and to mitigate the damage of potential accidents.
  • List the key elements of the product life cycle for equipment designed to ensure explosion safety.
  • Explain the basics of the legal environment of explosion safety based on existing directives.

Core content

The course applies learning engagement techniques (e.g., quizzes) and features lectures based on IECEx and ATEX directives covering:

1. Basic principles of explosion protection

  • Primary explosion protection
  • Avoiding explosive mixture formation
  • Secondary explosion protection
  • Avoiding ignition

2. Explosion protection techniques 

  • Tertiary explosion protection 
  • Prevention approaches 
  • The need for controlled explosions 

3. Regulations around the globe

4. Applied methodologies

  • Qualitative risk assessment based on bowtie analysis
  • Modelling explosive mixture formation and propagation
  • Data-driven hazard detection and mitigation

5. Industrial case studies with a particular focus on hydrogen

Who should attend

The course is ideal for:

  • employees working with materials that can form explosive mixtures,
  • engineers who wish to add explosion protection to existing/future industrial pipelines,
  • researchers and students with an appetite to learn about the hazards associated with hydrogen-based propulsion and the associated infrastructure,
  • facility managers who would like to understand the necessity of explosion protection,
  • authorities, investigators (incl. CSI).

It is recommended that attendees possess relevant experience and/or hold an appropriate degree in science or engineering.
