DSEAR Risk Assessment

DSEAR protects workers and others who may be at risk from dangerous substances that can cause a fire, explosion or spontaneous combustion event.

DSEAR puts responsibilities and actions on employers and the self-employed to protect people from these risks by implementing a strict set of regulations to abide by.

What is a DSEAR Risk Assessment?

Under the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR), if you store, handle or use potentially dangerous or explosive substances in your workplace, a systematic review is required. This is called a DSEAR Risk Assessment. These strict regulations focus on protecting against risks from fire and explosion, which might occur from dangerous substances being used or being present in the workplace.

Does my business require a DSEAR Risk Assessment?

Dangerous and explosive substances can be found in a wide range of premises. If your workplace has dangerous substances present, in use, or produced it is highly recommended that a DSEAR Risk Assessment is carried out.

  • Solvents
  • Paints
  • Varnishes
  • Flammable gases, such as liquid petroleum gas (LPG)
  • Dusts from machining and sanding operations,
  • Dusts from foodstuffs,
  • Pressurised gases
  • Substances corrosive to metal.

A duty holder will need to be nominated by the business to have ultimate control of the DSEAR risk assessment and its actions. We can take the role of duty holder within your business, allowing your business to be fully compliant.

Does diesel need to be included in a DSEAR risk assessment?

Yes it does. Diesel was reclassified as a ‘flammable liquid’ in 2008 and again in 2016 to bring it within the scope of DSEAR. If your business handles diesel, please contact us for a DSEAR Risk Assessment.

What happens during a DSEAR Risk Assessment?

A DSEAR Assessment from our experienced specialist consultant includes the following:

  • A Site visit, including time spent with key members of the team to discuss existing processes, procedures and protocols, followed by investigation via a full site walkaround. All aspects of work need to be considered as part of this process to ensure that the implementation of DSEAR is thorough and effective.
  • Samples may be taken of potentially explosive materials, and COSHH records examined. Dangerous substances are considered to include flammable liquids in any form, flammable fumes and vapours, and any non-inert dusts suspended or transferred in the air (eg, in blending processes or LEV).
  • A review of any potentially explosive atmospheres includes investigating the presence of gas, mist, dust or vapour which has the potential to catch fire or explode. The atmosphere within a confined space is also a particular cause of concern.
  • Full risk assessment, action plan and Hazardous Area Classification – this is one of the most important parts of any DSEAR Assessment is the establishment of ATEX zones. We will assist with zoning plans for both gases and vapours and for dusts.
  • Consultation and support on implementation – It is important that a bespoke approach is taken to your site and activities. We offer ongoing support, including training, awareness and support with written procedures.

What does ATEX mean, and how does the process apply?

The ATEX directive refers to two European Directives for controlling explosive atmospheres. The requirement for understanding ATEX and ensuring the proper control measures are put into place is all part of a thorough DSEAR Assessment.

The prevention or control of the release of dangerous substances or sources of ignition is two of the most commonly used methods of reducing risk. An assessment of the correct equipment to be used in the appropriately zoned area of your business will also assist with your control measures. For more information on ATEX zoning and the DSEAR Assessment process, contact us today.
