Consequence Modelling - EFFECTS Blogs

This blog emphasises the vital role of consequence modelling in assessing the impact of a runaway chemical reaction. Using T2 Laboratories incident data, it showcases EFFECTS—Gexcon’s integral consequence modelling software—for simulating and quantifying the effects of a runaway reaction, particularly explosions.

Consequence analysis is a critical aspect of process safety and risk management. Here are 10 crucial considerations to ensure a successful analysis.

Find out how to model the consequences of atmospheric dispersion for an accidental toxic release with EFFECTS consequence modelling software.

The early empirical approach to understand the tank overfilling scenario from the Buncefield accident was limited in its application.

Gexcon has expanded the model to calculate the vapour cloud generation due to the overfilling of a tank containing volatile liquid to consider other materials and (weather) conditions, which we will explain at the 2022 International Loss Prevention Symposium.

The resulting fireball phenomenon from a potential hydrogen release is still being modelled using traditional and potentially misleading methods.

During the 17th EFCE International Symposium on Loss Prevention and Safety Promotion in Process Industries, Gexcon’s Senior Research Scientist Hans Boot will present a paper entitled “Why a Hydrogen fireball should not be modelled as a BLEVE event”.

VCEs are generally seen as one of the most destructive accident scenarios in petrochemical operations. That is the reason why predicting potential consequences of VCEs is of extreme importance in safety assessments because this allows us to take mitigating measures adapted to the expected consequences.

This blog explains explain how a tank overfilling phenomenon can lead to the generation of a very flammable vapour cloud, and how this phenomenon can be simulated in Gexcon’s consequence modelling software EFFECTS.

Translating toxic concentrations into consequences requires a completely different approach than used with flammable clouds.

In this blog, we will try to explain the basics about deriving consequences from releases leading to a toxic cloud.

The physical state of the chemical and its typical properties are extremely important when evaluating a loss of containment scenario.

Both pool and warehouse fires can result in highly toxic fumes. The assessment of the toxic concentration levels of these combustion products transported along the plume trajectory is of utmost importance. Safety professionals can use this information for hazard identification, safety analysis and emergency planning.

This article will explain the importance of assessing the consequences of a potential release of a hazardous chemical substance and introduce you to the different dangerous phenomena that can occur upon such a loss of containment scenario.

Heat radiation from a pool fire causes a heat flux with the potential to cause damage to objects in the surrounding area.

That is why it is highly relevant to assess the consequences of such a scenario to help safety professionals devise prevention and mitigation measures so that accidental releases can either be prevented or their consequences minimized.

In this blog post, Sonia Ruiz, Gexcon’s Research Scientist, explains how easy it is to use background maps in EFFECTS.

To provide insights on safety, we should try to answer: “What can go wrong?”, “What are the consequences?” and “Why safety risks DO matter?”

Releases of ammonia can have potentially harmful effects on workers and the public. If ammonia is under pressure, the risk of exposure increases since larger quantities of the refrigerant has the potential for rapid release into the air.

EFFECTS consequence modelling software can be used to analyse the consequence of smoke plume hazards arising from warehouse or pool fire.

Did you know that our consequence modelling software EFFECTS has a dedicated model to calculate the plume rise phenomenon due to warehouse or pool fires? This model not only simulates the rising behaviour of the hot smoke plume but also the effect
