ATEX Directive


ATEX Manufacturers Directive 94/9/EC

This directive defines each of the following product groups for use in potentially explosive atmospheres:  

  • Electrical and non-electrical equipment
  • Electrical and non-electrical protective systems
  • Electrical and non-electrical components
  • Electrical and non-electrical safety devices

The directive places responsibilities on the manufacturer of these products. The main responsibility of the manufacturer is to prevent the formation and ignition of explosive atmospheres. This may be achieved by using one of the well-established protection concepts (such as flameproof protection, or intrinsic safety), or by proving compliance directly against a set of 'essential health and safety requirements', which are given in the directive.
Note: This directive may also be heard described as ATEX '100a' or 'ATEX 95', after the enabling articles of European treaties.

ATEX User Directive 99/92/EC

This directive is concerned with the health and safety of workers with relation to potentially explosive atmospheres. It places responsibilities on an employer. Typical responsibilities include:

  • The assessment of risks
  • Hazardous Area Classification
  • Mitigation &/or removal of risks
  • Preparation of an Explosion Protection Document
  • The provision of suitable warning signs for areas where explosive atmospheres may form

Note: This directive may also be heard described as ATEX '137', after the enabling article of the Treaty of Rome.

Dangerous Substances and Explosive Atmospheres Regulations (DSEAR)

From July 2006, employers must have completed the risk assessment, classification and documentation of their workplace and personnel. This also includes training and procedures, where potentially explosive atmospheres or dangerous substances may occur, as required under the UK Dangerous Substances and Explosive Atmospheres Regulations (DSEAR, Statutory Instrument 2002/2776).

We can help ensure that your workplace, including hazardous area electrical and mechanical installations meet the requirements laid down and that you comply with all the relevant Standards.
