DSEAR Risk Assessment at a glance

What is a DSEAR Risk Assessment?

A DSEAR Risk Assessment identifies where fire, explosion or similar events could occur due to dangerous substances. It examines how flammable liquids, gases, vapours or dusts are used and stored, whether explosive atmospheres may form, and whether equipment or processes could ignite them.

 

It ensures your business has the right controls in place – and that those controls are practical, proportionate and compliant with legislation.

Who is this service for?

This service is suitable for any business that handles, stores, generates or disposes of dangerous substances, including:

  • Manufacturers
  • Workshops and engineering environments
  • Automotive and fuel-handling operations
  • Food and grain processing (combustible dusts)
  • Laboratories and chemical storage
  • Businesses using solvents, aerosols or cleaning agents

If you’re unsure whether DSEAR applies to your business, we can tell you quickly so please contact us for a no-obligation discussion.

What outcomes can you expect?

With our DSEAR Risk Assessments you can expect:

  • Clear understanding of your fire and explosion risks
  • A practical, prioritised action plan tailored to your operations

  • Improved safety, reduced risk and reassurance for you and your team
  • A structured, professional report understood by insurers, clients and regulators.

Where do we provide this service?

Our consultants are based throughout the UK, so we always have a consultant that will be able to support you.

Is a DSEAR Risk Assessment a legal requirement?

Yes. If your business uses, stores or creates dangerous substances that could form flammable or explosive atmospheres, DSEAR requires you to carry out a formal DSEAR Risk Assessment.

This includes:

 

  • Flammable liquids
  • Flammable gases
  • Flammable vapours
  • Combustible or explosive dusts
  • Aerosols and certain cleaning products
  • Process-generated vapours or residues

DSEAR requires you to:

 

  • Identify and assess the risks
  • Reduce or eliminate them where possible
  • Put suitable controls and emergency procedures in place
  • Provide appropriate information and training to employees
  • Classify hazardous zones where explosive atmospheres may occur
  • Ensure equipment in those zones is suitable and safe to use

How our DSEAR Risk Assessment works

1

Understand your operations

We begin with an initial discussion to understand your processes, volumes handled, equipment, ventilation and existing controls. We also review SDS sheets and other relevant documents.

2

On-site DSEAR survey

A qualified consultant visits your site to identify dangerous substances, how they’re used and whether explosive atmospheres may form. We also inspect ignition sources, equipment suitability, dust controls, ventilation and housekeeping.

3

Zoning and hazard evaluation

Where necessary, we identify and classify hazardous zones and explain what the classifications mean for equipment, controls and signage.

4

Recommendations and compliance plan

We provide a clear and prioritised action plan to ensure DSEAR compliance – with proportionate, cost-effective solutions rather than over-engineered or unnecessary changes.
