DSEAR Compliance

DSEAR Compliance Regulations require Employers to undertake an assessment of risk associated with their work activities, or manufactured products that could present a risk of a fire or explosion, and would then subsequently need to consider the introduction of “ special precautions”, in relation to the control of potential ignition sources.

The DSEAR Compliance assessment looks critically at the characteristics of any workplace materials, solids, or liquids, or gases, in order to determine:

The ways in which uncontrolled releases could occur

The quantity, and its material characteristics, flammability, vapor density, a flashpoint that would affect its material behavior to forming a potentially flammable and explosive atmosphere.

To assess the likelihood of such a release, and the consequences when in the presence of any ignition source.

To make recommendations necessary in order to meet the hierarchical principles of DSEAR Regulations.

Common work sectors to which DSEAR Compliance would apply:

  • Chemical storage, process manufacturing, handling, and use
  • Motor vehicle maintenance
  • Paint spraying
  • Metal blasting and cleaning
  • Food manufacturing- use of large quantities of sugar, or flour
  • Anaerobic digestion- to energy
  • Water treatment
  • Hospitals- medical gases
  • Fuel storage
  • Waste treatment

DSEAR Compliance is a requirement for any site with potentially flammable atmospheres.

Compass HSC is experienced in carrying out hazardous area classifications, explosion risk assessments, and most importantly in giving pragmatic, cost-effective risk reduction advice in accordance with the hierarchy specified within the regulations.

Review/Gap Analysis

We gain a full understanding of your site, processes, and procedures, reviewing all available documentation, checking all hazardous substances in use, and confirming the required compliance levels. We then issue a report to identify the scope and action plan.

• Detailed Assessments

We complete your hazardous area classifications, review mechanical/electrical equipment, and identify ignition sources. We set out your required actions based on cost-effective and practical solutions, and a further report is issued detailing all area classifications, recommendations, and further actions.

• Operation/Procedures

We review your training needs, operating/maintenance procedures and emergency plans to ensure that continued compliance can be delivered. We issue a detailed action plan and where appropriate can schedule ongoing reviews and audits.

We understand the complexities that DSEAR requires employers to assess, take a look at our frequently asked questions, if you can’t see what you’re looking for, ask us your question below.
Is DSEAR a legal requirement?
The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) require employers to control the risks to safety from fire, explosions, and substances corrosive to metals.
What are DSEAR regulations?
(DSEAR) are concerned with preventing or limiting the harmful effects of fires, explosions and similar energy-releasing events and corrosion to metals.
How often should a DSEAR assessment be carried out?
In fact the HSE usually recommends that DSEAR is updated every 3-5 years depending upon the risk levels of the operations.
Who can carry out a DSEAR risk assessment?
DSEAR requires employers to carry out risk assessments before commencing any new work activity involving dangerous substances. The regulations state that the risk assessment shall include consideration of: The hazardous properties of the substance. Information on safety provided by the supplier. Contact Compass HSC to carry out your DSEAR Compliance risk assessment.
What is a DSEAR zone?
Zoning. Hazardous areas are defined in DSEAR as “any place in which an explosive atmosphere may occur in quantities such as to require special precautions to protect the safety of workers”. Area classification is a method of analysing and classifying the environment where explosive gas atmospheres may occur.
