Hazardous Releases Services
The modelling of hazardous releases can be required for emergency situations, such as a liquid spill, catastrophic failure of a tank or rupture of a pipeline. Toxic or flammable substances, such as ammonia, chlorine and Liquid Natural Gas (LNG), are often considered.

- These assessments may be required by regulators such as the UK Health and Safety Executive (HSE) for Control of Major Accident Hazards (COMAH) assessments.
- Scenarios can be complex, requiring investigation of emission characteristics and dispersion pathways under different meteorological conditions.
- Depending on the nature of the release, CERC`s industrial pollution model ADMS or dense gas model GASTAR, or a combination of the two, may be used. If the initial source of the release is a liquid spill, CERC`s model LSMS may be used to determine emission rates to air.
- Depending on the situation, model outputs may be compared with a range of threshold values, such as toxic loads (doses), exposure limits and flammability levels.
- We also use ADMS to assess the likely impacts of uncontrolled combustion, such as waste or warehouse fires, or emergency flaring.
- CERC has worked behind the scenes on several recent high-profile legal cases. We can provide expert advice and Expert Witness services to support our findings.
