Compliance

About ATEX Assessments

ATEX is the name given to the European Directive to ensure that all EU member states create appropriate legislation so that the health and safety protection of employees from an explosion caused by work activity is reduced.

Compliance is implemented in the UK through the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR).  Manufacturer’s of equipment to be used in potentially flammable atmospheres must comply with the Equipment for Use in Potentially Explosive Atmospheres Regulations (EPS).

For businesses in the UK, or for those wishing to comply with DSEAR, you can find out more on our dedicated DSEAR and HAC page. 

Understanding ATEX Regulations

ATEX applies to all equipment and places of work, within the European Union and the European Economic Area (EEA) and aims to protect workers against risks arising from explosive atmospheres. An employer must take organisational and/or technical measures to:

  • prevent the formation of explosive atmospheres, or where the nature of the activity does not allow that, it should avoid the ignition of explosive atmospheres
  • mitigate the detrimental effects of an explosion to ensure the health and safety of workers
  • where necessary, these measures shall be combined and/or supplemented with measures to prevent the propagation of explosions
 

Employers must also assess the specific risks from explosive atmospheres, taking account at least of:

  • the likelihood that explosive atmospheres will occur and their persistence
  • the likelihood that ignition sources, including electrostatic discharges, will be present and become active and effective
  • the installations, substances used, processes and their possible interactions
  • the scale of the anticipated effects

Understanding CAD (Chemical Agents Directive)

The Chemical Agents Directive aims to promote and improve the safety and health of workers at their place of work. As ATEX only covers explosive atmospheres, the CAD directive focuses on risks related with chemical agents. Considering hazardous chemical agents, CAD concentrates on the occupational exposure of potentially hazardous chemical agents and its direct risk to fires, explosions and chemical reaction hazards. CAD covers all hazardous chemical agents including:

  • elements or compounds either on its own or admixed,
  • chemicals in natural states or produced, used or released.
  • elements released as waste (whether intentionally or not)
  • elements that may give rise to explosive mixtures
  • all chemical agents whether placed on the market or not
 

For explosive atmospheres both Directives apply, ATEX is more specific for the requirements related to explosive atmospheres, CAD can apply. Furthermore, for all other fires and explosions CAD will apply. This includes explosive mixtures outside the “atmospheric” range (oxygen concentration, pressure, temperature)
