Who Needs ATEX Compliance?
ATEX obligations fall on two distinct groups under two separate directives—and the requirements differ significantly. Understanding which directive applies to you, and what it demands, is the starting point for compliance.
The Equipment Directive: Economic Operators
The ATEX Equipment Directive (2014/34/EU) applies to "economic operators"—anyone in the commercial chain of placing ATEX products on the EU market:
- Manufacturers: Anyone who manufactures products or has them designed/manufactured and markets them under their own name or trademark. This includes EU and non-EU manufacturers.
- Authorised representatives: Anyone established in the EU mandated by a manufacturer to act on their behalf for specified tasks.
- Importers: Anyone established in the EU who places a product from a third country on the EU market. The importer becomes responsible for ensuring compliance.
- Distributors: Anyone in the supply chain who makes products available on the market (other than manufacturer or importer).
Importantly, if you modify a product or market it under your own name, you become the manufacturer with full manufacturer obligations—regardless of who originally made it.
The Workplace Directive: Employers
The ATEX Workplace Directive (1999/92/EC) applies to employers whose workers may be exposed to explosive atmospheres. If your workplace handles, processes, stores, or uses flammable gases, vapours, mists, or combustible dusts that could form explosive mixtures with air, you have obligations.
Industries commonly affected include:
- Oil and gas (exploration, refining, distribution)
- Chemical and petrochemical manufacturing
- Pharmaceutical production
- Food and beverage processing (flour, sugar, grain dusts)
- Wood processing (sawdust)
- Metal processing (aluminium, magnesium dusts)
- Paint and coatings manufacture and application
- Printing (solvent vapours)
- Waste treatment and biogas facilities
- Brewing and distilling
Scope Exclusions to Know
Neither directive applies universally. The Equipment Directive excludes medical devices, domestic/non-commercial equipment (unless specifically for explosive atmospheres), personal protective equipment, seagoing vessels, and military applications. The Workplace Directive excludes medical treatment areas, gas appliance use, explosives/unstable chemicals handling, mineral extraction (covered by mining directives), and transport vehicles.
What If You're Both?
Many organisations face obligations under both directives. A chemical plant, for example, must ensure equipment purchased meets Equipment Directive requirements (checking ATEX marking, verifying suitability for zones) AND meet Workplace Directive requirements (risk assessment, zone classification, EPD, worker training).
The directives complement each other: the Equipment Directive ensures suitable equipment exists; the Workplace Directive ensures it's correctly selected, installed, and maintained in properly managed hazardous areas.
Non-EU Manufacturers
Manufacturers outside the EU aren't directly subject to EU law but effectively must comply if they want EU market access. They can either appoint an authorised representative in the EU or rely on EU-based importers. Either way, someone within the EU takes legal responsibility for compliance.
End Users' Role
End users aren't "economic operators" under the Equipment Directive—they don't need to certify equipment. But they must ensure equipment is appropriate for its intended use, properly installed per manufacturer instructions, maintained according to inspection requirements, and operated within its design parameters. Misusing correctly certified equipment doesn't absolve the end user of responsibility.
Small Businesses
The directives apply regardless of company size. A small workshop with solvent vapours has the same legal obligations as a major refinery—though the scale and complexity of compliance activities will differ with the extent of hazards. The Workplace Directive explicitly notes that measures should avoid imposing disproportionate burdens on small and medium enterprises while still ensuring worker protection.
