DSEAR Risk Assessment Consultants

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) require every employer to assess and control risks from flammable gases, vapours, mists, and dusts. Arthian’s DSEAR risk assessment consultants deliver clear, audit‑ready documentation and practical compliance services to help organisations obtain full DSEAR compliance.
 
We provide:

     

  • Comprehensive DSEAR site surveys and risk assessments
  • Ignition source identification and control strategies
  • Explosion protection and prevention measures
  • Audit‑ready documentation and regulator engagement support

 
Our UK DSEAR consultants make complex requirements clear, proportionate, and tailored to your operations — helping you stay safe, compliant, and confident.

What Is DSEAR and Why Does It Matter?

The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) require employers to assess and control risks from flammable gases, vapours, mists, dusts and corrosive substances. A DSEAR assessment is legally required and employers must:

     

  • Identify hazards and assess risks of explosive atmospheres for any workplace handling dangerous substances
  • Implement proportionate control measures when introducing new processes or materials
  • Review assessments after incidents, near misses, or process changes
  • Maintain compliance through regular reassessment (typically every 1–5 years) as part of ongoing compliance

 
Failure to comply can result in enforcement action, fines, and increased risk of fire or explosion. Arthian’s DSEAR compliance services ensure your organisation is protected and prepared.

Our DSEAR Services

We help clients meet their duties under DSEAR by identifying hazards, evaluating ignition risks, and recommending proportionate controls.
