Gas, Vapour and Dust Explosion Hazards, Protection, Mitigation and Prediction

What will I learn?
You’ll review recent experimental and theoretical research, with particular emphasis on information relating to the explosion development in obstacle-congested volumes and process vessels on confined and partially confined configurations.

How will I benefit?
With presentations from world experts in explosion, you’ll gain detailed academic knowledge of the subject and have the opportunity to practically apply what you have learned.

This course also forms part of an MSc Masters programme (full time or part time) in Fire and Explosion Engineering.

The 2019 course programme and leaflet will be available approximately 3 months prior to the course. However, you can view and download the 2018 course details for further information by clicking the course leaflet and course programme link.

Day 1: Flammability and explosions

  • Explosion stoichiometry and application to BLEVES, tank explosions and furnace explosions
  • Flammability and ventilation explosion protection
  • Flash point and fuel tank explosions, TWA flight disaster
  • Explosion protection using inerting
  • Flame reactivity assessment; burning velocities or the KG parameters
  • Self-acceleration of laminar propagating flames into cellular flames and then turbulent flames. The implications for KG as a function of vessel volume. The self-acceleration of gas explosion flames in the Buncefield incident and the role of large-scale turbulence in the generation of fast flames and high overpressure
  • Flame arrestors and explosion.

Day 2: Characteristics of gas and dust explosions, vent and suppression design

  • Dust explosion characterisation and the influence of dust size distribution
  • Explosion suppression: product, performance, system design
  • Theory of venting with application to the EU vent design equation
  • Explosion venting and flameless explosion venting: product, performance, vent system design
  • Venting of non-compact vessels (L/D >2)
  • Explosion in complex industrial situations: interconnected vessels.

Day 3: Vapour cloud explosions

  • Managing explosion safety
  • Hydrocarbon releases – source term considerations
  • Important parameters in turbulent explosions/example problems
  • Flame acceleration and transition to detonations
  • The role of large-scale experiments in explaining vapour cloud explosions
  • Explosion mitigation by general area water deluge.

Day 4: Blast prediction and blast response

  • Blast loading identification and blast effects on structures
  • Review of explosion simulation methods (TNT/Multi-Energy)
  • The Congestion Assessment Method (CAM)
  • A phenomenological model (SCOPE) – details and use in exceedance calculations
  • Experimental scaling
  • Example problems
  • LNG Hazards.

Day 5: Explosion assessment: capability, validation, limitations and applications of CFD

  • Explosion control based on barrier methods
  • Criteria for evaluation of explosion models
  • Flammable cloud volume: source term to explosion models
  • The Buncefield Incident 2005
  • Example problems – demonstration of CFD modelling exercises.


This course is suitable for you if you’re an engineer or scientist involved in both the offshore sector and the onshore chemical process and nuclear industries.  More specifically, the course will be of benefit if you’re an experienced or newly appointed:

  • explosion safety consultant or engineer
  • research and development scientist or engineer
  • loss prevention and facilities manager
  • risk and insurance assessor
  • civil engineer or process plant designer
  • explosion protection systems manufacturer or designer.

"Strikes a balance between academic knowledge and practical application to provide a learning opportunity for a broad range of backgrounds with varying previous understanding."

"Nowhere else can you get such a wide range of presentations with world experts in explosion."
