DSEAR: Gases and Liquids

Live Online

18 September 2024 - 19 September 2024

HSE runs three courses to help employers comply with the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR).

  • DSEAR: Gases and Liquids
  • DSEAR: Hazardous Area Classification for Gases and Liquids
  • DSEAR: Controlling Dust Explosion Risks

While there is some overlap between the courses delegates can attend one or more courses depending on which area of DSEAR they are interested in.


DSEAR places duties on employers and the self-employed to protect employees, contractors and others from the risks from fires and explosions related to dangerous substances stored and used in the workplace.

This course explains the duties that DSEAR places on employers and the actions needed to comply with them. It focuses particularly on the assessment of risks and the application of controls to both minimise and mitigate those risks.

Learning outcomes

Delegates will be provided with information that will help them to:

  • Know their legal duties under DSEAR
  • Be able to act as an intelligent customer when commissioning DSEAR assessments
  • Be able to understand the key concepts related to hazardous area classification and common approaches
  • Be able to identify potential ignition sources and select appropriate ATEX rated equipment

What the course will cover

The course will help delegates understand their legal duties under DSEAR, as well as the moral and financial reasons why they should comply with the regulations. Delegates will be shown how to assess, control and mitigate the risk from dangerous substances and will be introduced to the equipment for use in explosive atmospheres. Delegates will be introduced to the key definitions and concept areas of hazardous area classification and the standards that apply. The course also looks at hazardous area classification for laboratories and small-scale operations, as well as covering mists and the control of ignition sources.

Who should attend?

This course is aimed at managers and supervisors of process plant and operations where dangerous substances are used or stored, or safety specialists who need to understand how to manage the risks from dangerous substances within the framework of the DSEAR duties.  This course is intended to allow them to act as an intelligent customer when commissioning work related to DSEAR.
