Dangerous Substances and Explosive Atmospheres Regulations 2002

  • Page 10 of 11


These Regulations implement the Chemical Agents Directive 98/24/EC (CAD) and the Explosives Atmospheres Directive 99/92/EC (ATEX 137). Known also as DSEAR, the regulations came into effect in the UK on 5 December2002.

DSEAR require employers and the self employed to:

  • Carry out a risk assessment of any work activities involving dangerous substances
  • Provide technical and organisational measures to eliminate or reduce as far as reasonably practicable the identified risks
  • Provide equipment and procedures to deal with accidents and emergencies
  • Classify places where explosive atmospheres may occur into zones and to mark those zones where necessary

Overall, DSEAR can be seen as complimentary to the general duty to manage risks under the Management of Health and Safety at Work Regulations 1999, making explicit good practices for reducing the risk to persons from fires, explosions and energy- releasing events which in turn are caused by dangerous substances such as flammable solvents and fuels.

It applies to substances that are known to be dangerous that include petrol and LPG and it is aimed at protecting persons from dangerous substances.

DSEAR requires employers (or self employed persons) to carry out a risk assessment before commencing any new work activity and in the case of an employer with 5 or more employees, to record the significant findings of the assessment as soon as possible that includes:

  • The measures taken to eliminate and/or reduce the risk
  • Sufficient information to show the workplace and work equipment will be safe during operation and maintenance including any hazardous zones, any special measures to ensure the co-ordination of safety measures and procedures, when employers share a workplace
  • Arrangements to deal with accidents, incidents and emergencies
  • Measures taken to inform, instruct and train employees
  • The risk assessment required by DSEAR is an identification and careful examination of the dangerous substances present in the workplace and the work activities involved

DSEAR reflects the safety strategy of ELIMINATION, CONTROL AND MITIGATION For further details, contact the Petroleum Licensing Officer.
