Main requirements for employers under DSEAR legislation

Atex 640

From July 2006 employers must;

  • Carry out assessment of the fire & explosion risks of any work activities involving dangerous substances, including thermal oils and synthetics

  • Provide measures to eliminate, or reduce as far as is reasonably practicable, the identified fire & explosion risks.  For heat transfer oil this means monitoring of flashpoints by representative hot, closed sampling and to sustain and/or restore flashpoints by venting procedures or dilutions where the former is not an option.

  • Apply measures, so far as is reasonably practicable, to control risks and to mitigate the detrimental effects of a fire or explosion and maintain security of the system to prevent leaks and remove sources of ignition.

  • Provide equipment & procedures to deal with accidents & emergencies

  • Provide employees with thermal fluid management training and precautionary training. This includes ensuring engineers are aware for the need to sample correctly in order to monitor and manage flashpoints

Where explosive atmospheres may occur (also see Note 1 above):

  • The workplace should be classified as hazardous & non-hazardous areas

  • Hazardous places to be classified into zones on the basis of frequency and duration of an explosive atmosphere and where necessary marked with a sign

  • Equipment in classified zones should be safe & satisfy the requirements of Equipment & Protective Systems intended for use in potentially Explosive Atmospheres 1996
  • The workplace should be verified as meeting the requirements of DSEAR by a competent person. This would usually be the health and safety manager/director, engineering manager or operations manager/director.
