DSEAR / ATEX

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) 2002 are the UK enactment of the European Directive ATEX 137 and part of the Chemical Agents Directive. Dangerous substances include those capable of forming an explosive atmosphere as well as those capable of highly energetic or runaway reactions. DSEAR place a duty on employers to protect members of the public as well as employees from the risks of fires, explosions and similar events.

DSEAR applies to all workplaces where dangerous substances are present, used or produced. This encompasses all activities such as processing, packing, warehousing, storage and transportation in addition to planned or emergency maintenance.

DSEAR requires employers to:

  • Assess the fire and explosion risks caused by dangerous substances and work activities.
  • Eliminate those risks or put in place measures to reduce the effect of any incidents.
  • Classify areas where explosive atmospheres may occur into zones.
  • Mark hazardous zones with signs where there is a benefit in terms of risk reduction.
  • Prepare plans and procedures to deal with accidents, incidents and emergencies.
  • Inform and train employees to control or deal with those risks.
  • Select equipment and protective systems suitable for the hazardous zones.
  • Ensure that the overall explosion safety measures are confirmed (verified) as being suitable by a competent person or organisation before any work area containing zones comes into operation for the first time.
