The simplest way to think about it In practice, UK sites use DSEAR to manage workplace explosion risk and use ATEX-related equipment standards and markings to select suitable kit for zoned areas. Canonical URL: https://www.safety-management.co.uk/news/dsear-vs-atex-whats-the-difference-and-which-applies-to-you ## Article The simplest way to think about it - **DSEAR** is UK law requiring employers to assess and control risks from dangerous substances and explosive atmospheres. - **ATEX** is commonly used as shorthand for two EU directives covering: - workplace minimum requirements for explosive atmospheres (often called “ATEX 137”) - equipment intended for explosive atmospheres (product directive) In practice, UK sites use DSEAR to manage workplace explosion risk and use ATEX-related equipment standards and markings to select suitable kit for zoned areas. What applies to your site? Most of the time, the answer is: both in different ways. - DSEAR drives your **risk assessment, zoning, control measures, and safe systems** - ATEX equipment requirements drive **what equipment you buy and install in zoned areas** (and how it’s marked) HSE explicitly links DSEAR zoning to the selection of equipment and protective systems. Common confusion that causes real risk - “We have ATEX equipment so we’re covered.” Not unless your DSEAR assessment and zoning justify it and your controls are maintained. - “We don’t need zoning because it’s only dust.” Combustible dust is precisely where people miss hazard formation, particularly in food and milling. - “Our consultant gave us a huge report so it must be right.” Length is not competence. Clarity is. What you should have on file - DSEAR assessment (current, site-specific, action-driven) - Zoning drawings (if zones exist) - Equipment suitability evidence and maintenance rules - Training and contractor controls for non-routine work If you want, we can review your current DSEAR and tell you whether your zoning and equipment choices actually align, or whether you have hidden ignition exposure. ## Related guidance - [Practical Health & Safety Support: Knowing Where to Start and What to Do Next](/news/practical-health-safety-support-knowing-where-to-start-and-what-to-do-next): Managing health and safety can feel straightforward when everything is running smoothly.
