DSEAR Gas & Liquid Explosion Risk Assessment for Duty Holders

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) require duty holders to assess and control fire and explosion risks where flammable gases and vapours from liquids are stored, transferred or used. In practice, regulators and auditors expect duty holders to explain how releases were identified, how ignition was controlled and why their hazardous area classification can be justified. When that understanding varies across a site, risk assessments become inconsistent, decisions on ventilation, equipment selection and zoning are harder to defend and the health and safety team must fill the gaps.

The DSEAR Gas and Liquid Explosion Risk Assessment toolkit brings together our online course and supporting resources so you can build duty-holder competence quickly and consistently. It gives duty holders a practical framework for identifying dangerous substances, evaluating release and ignition scenarios, applying the DSEAR hierarchy of control and following the full risk assessment process through a real workplace example.

Duty holders can use this toolkit to support a consistent approach to gas and vapour risk assessment across teams, departments and sites and to incorporate the training into existing DSEAR, COSHH or contractor-management programmes.
