The manufacturer of the equipment, when placing products or equipment on the market should provide a Declaration of Conformity confirming that his products are identical to the samples originally type tested by the Ex Notified Body, and that they meet the Essential Health & Safety Requirements of the Directive 94/9/EC. This should include compliance with the latest technical knowledge, or state of the art arising out of substantive change in the standards affecting that product or equipment, which may have occurred after the original certificate was granted. For further information on the subject Chapter 10 of the ATEX 94/9/EC Directive Guidelines can be consulted.

ATEX 137 Directive (1999/92/EC)

Operators and Contractors must comply with regulations laid down to ensure the Safety of Workers and follow Installation Codes of Practice that are designed to reduce risk. Under UK law, the Health & Safety at Work Act makes employers responsible for ensuring the health and safety of their employees and also of the public, if they are at risk from dangerous substances.

The Protection of Workers at Risk from Potentially Explosive Atmospheres Directive 1999/92/EC (ATEX 137) establishes minimum requirements to protect workers against hazards from explosive atmospheres.

It deals only with explosive atmospheres and compliance was mandatory from 1st July 2003 for new installations and from 1st July 2006 for existing installations.

Extracts from the ATEX worker protection directive (1999/92/EC) - ATEX 137

Employers are required to prepare an Explosion Protection Document that clearly demonstrates in particular:

  • That explosion risks have been assessed
  • That adequate measures will be taken to attain the aims of the directive
  • Those places which have been classified into zones in accordance with Annex I of the directive
  • Those places where minimum requirements set out in Annex II of the directive will apply
  • That the workplace, and work equipment, including warning devices, are designed, operated and maintained with due regard for safety,
  • That in accordance with Council directive 89/655/EEC arrangements have been made for the safe use of equipment.

The Explosion Protection Document shall be drawn up prior to the commencement of work and be revised when the workplace, work equipment or organisation of the work undergoes significant changes, extensions or conversions.

UK DSEAR Regulations 2002 & EC Chemical Agents (C.A.D.)

In the United Kingdom, the Dangerous Substances in Explosible Atmospheres Regulations (DSEAR) which came into force on December 9th 2002, requires operators, under a Statutory Instrument (S.I. 2002 Number 2776) of the UK government, to make use of the ATEX 137 and the EC Chemical Agents (CAD) 98/24/EC directives to ensure safety in the work place.

The ultimate object of the legislation is to ensure that as a minimum, the Essential Health and Safety requirements of the new approach directives are met.
