Regulatory Compliance

Geosyntec works closely with its clients to ensure that industry-specific regulations and standards are strictly adhered to at all times. We support clients with:

  • Document Preparation: Control of Major Accident Hazards (COMAH) Report, Safety Case, Health, Safety and Environmental Impact Assessment (HSEIA), Environmental, Social, and Health Impact Assessment (ESHIA)
  • Auditing: Process Safety Management (PSM) System, Atmosphères Explosibles (ATEX), Dangerous Substances and Explosive Atmospheres Regulations (DSEAR), and COMAH Compliance
  • Stakeholder Communication

COMAH Compliance and Offshore Installations (Safety Case) Regulations

Geosyntec supports clients with COMAH and Offshore Safety Case reports on a regular basis. We work with clients operating both onshore and offshore major hazard facilities to ensure they are meeting their responsibilities to control major accidents, and that processes are in place to mitigate the consequences should an industrial accident occur.

DSEAR and ATEX Compliance

The European Union's ATEX regulations and the DSEAR regulations in the United Kingdom place requirements on employers to protect workers and visitors to sites at risk from explosive atmospheres. The regulations require employers to identify any dangerous substances present in their workplace and determine what fire and explosion risks they present. Geosyntec practitioners help clients to comply with all aspects of the regulations, including risk assessments to confirm that the risks associated with these substances are as low as practicable, designing safe systems of work and other risk reduction measures, developing emergency procedures, and providing training to personnel in the safe use of hazardous materials.

Geosyntec works across the water, oil and gas, and process and power industries to assist with DSEAR compliance. We can assess the hazardous properties of substances associated with on-site processes, including explosibility, flammability, and toxicity. Risks can then be assessed by looking at working practices, maintenance activities, the likelihood and persistence of explosive mixtures, and the  presence of ignition sources.

Gas turbine (GT) enclosures are potentially hazardous environments, due to hot surfaces and the potential for gas leaks that could lead to explosions. The United Kingdom's Health and Safety Executive (HSE) guidance note, PM84, and BS ISO 21789, provide information on how to meet the ATEX and DSEAR requirements – including requirements for CFD modeling. There is a correlation between the volume of leak gas in a GT closure and the blast overpressure that can be created if the gas ignites. Geosyntec uses CFD modeling to determine the volume of leaked gas and ensure that the ventilation system is correctly designed and optimized to prevent excessive overpressures. The CFD analysis is also used to determine appropriate gas detector settings for controlling leak gas volumes within the set limits.

Geosyntec has been undertaking these studies to improve support for clients for many years. We understand the implications of the standards and know how to propose and test simple modifications to a design, ensuring it will meet the standards. Key to this is an appreciation of the stoichiometric gas cloud calculation, and the methods used to efficiently identify the worst-case leak location.
