Consequence Modelling (including DSEAR)

To manage the consequences of a potential high hazard incident in the most appropriate way it's important to understand the possible impact it could have on people, property and the environment.

The Dangerous Substances and Explosive Atmosphere Regulations (DSEAR) are relevant for many businesses and require Hazardous Area Classification to be carried out in order to identify where flammable atmospheres may be present.

You can access our suite of tools, techniques, facilities and experts to help you fully understand the consequences of your major accident hazards, allowing you to best manage the risk profile of your business.

We have expertise in a very wide range of consequence modelling techniques ranging from very simple models to Computational Fluid Dynamics (CFD). For example, our specialist team can accurately model flammable substance releases, the dispersion of toxic chemical vapour releases, vapour clouds and fires including smoke movement.

We also share our knowledge through relevant training, and have developed an accurate and convenient hazardous area classification software tool: Quadvent 2.

As we advise and guide HSE inspectors, work with relevant industry bodies at a national level, and investigate when things go wrong we're uniquely placed to provide you with relevant and pragmatic support to help you demonstrate - and go beyond - regulatory compliance in your highly complex and technical world.
