ATEX/DSEAR Compliance

This is a specialist area for which many businesses do not have the in-house resources to achieve compliance in full.


DSEAR stands for The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) and is UK legislation. ATEX stands for Explosive Atmospheres Directive 99/92/EC (ATEX 137) and is EU legislation.

These regulations are designed to protect people and property from fires and explosive events due to use of dangerous substances (i.e. with potential to cause fire, explosion or other energy releasing scenarios) in the workplace. These typically include; flammable liquids, vapours, powders or dusts.

Do I need ATEX/DSEAR compliance?

If your business stores, handles and transports dangerous Substances, there is a good chance you will need compliance.

Industries that most commonly require DSEAR/ATEX include petrochemical and chemical manufacturers, food processors and pharmaceuticals.

Who enforces ATEX/DSEAR?

Primarily the HSE with some degree of involvement from Local Authorities, Fire Brigades and Petroleum Licensing Authorities. Non-compliant ATEX/DSEAR business have been issued with prohibition notices from the HSE and forced to achieve compliance before being granted permission to operate.
