DSEAR & ATEX Compliance Consultants

If your business stores, produces, transports or exposes staff member to explosive materials then it is essential for you to comply with the European DSEAR ATEX Directives.

Two ATEX Directives have been implemented throughout the European Community for the promotion of free trade of goods and to help increase the safety of workers. Compliance with the minimum Essential Health and Safety Requirements (EHSRs) is NOT optional; it is the law. Addison can assist you with your DSEAR compliance by advising you on what changes should be implemented in order to be fully compliant.

Addison Project has a great deal of expertise in the design and installation of instrument and electrical equipment and circuits in areas where flammable and explosive atmosphere could occur, making us well placed to guide you through the complex DSEAR ATEX requirements. We can arrange for site equipment surveys to be carried out, with management, production and implementation of the necessary systems, strategies and documentation put in place to support proof of initial and ongoing compliance with the DSEAR.

ATEX Minimum Requirements

The minimum requirements that you need to implement to ensure that you comply with the DSEAR ATEX Directives are as follows:

For ATEX 100a – 94/9/EC – The Equipment Directive
(Or in the UK, Statutory Instrument 1996 / 192 – The Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 1996)

  • EHSRs
  • Integrated explosion safety management systems must be in place
  • Consideration must be given to the environment in which the equipment will be used
  • Equipment must be marked for compliance (groups / categories)
  • Material selection in design and construction must be considered
  • Potential ignition sources must be identified
  • Risk caused by explosive mixtures of dust, vapour and gas to be identified

For ATEX 137 – 1999/92/EC – The Use Directive (Or in the UK, Statutory Instrument 2002 / 2776 – The DSEAR (Dangerous Substances and Explosive Atmospheres Regulations 2002)

  • Risk assessment
  • Provide coordinated compliance strategy
  • Eliminate or reduce risk so far as is reasonably practicable
  • Training
  • Written instructions and Permit to Work procedures
  • Warning signs
  • Identification of containers and pipes containing hazardous material
  • Classification of areas into zones
  • Selection of approved equipment (94/9/EC)
  • Regular inspection philosophy
  • Emergency response plans
  • Hazardous area classification

Hazardous Area Classification

Area classification is a procedure carried out by a skilled team to identify and quantify potential explosive atmospheres and assign hazardous area zones.

The procedure requires analysis of such data as flammable materials, equipment, site conditions and ventilation. Addison Project has a great deal of experience in hazardous area classification and the design and installation of electrical equipment and circuits in hazardous areas and we are therefore able to provide reliable advice on DSEAR ATEX regulations. We can offer expertise in a range of services tailored to suit your needs such as:

  • Chair and lead area classification meetings
  • Provide experienced process and electrical engineers to support the client’s own personnel
  • Carry out detailed plant, equipment and services surveys to ensure that your site meets the strict DSEAR’s.
  • Produce the necessary AutoCAD hazardous area plan and elevation layout drawings, with supporting calculations, data sheets and reports.

Addison Project can also give advice on the client’s requirements to implement a compliant maintenance and inspection strategy, including production of equipment inspection schedules and associated equipment location diagrams.
