DSEAR and Hazardous Area Classification

Do you store or handle dangerous substances under DSEAR?  These can include flammable gases, vapours or liquids, combustible dusts, oxidising materials, compressed gases, or materials corrosive to metal.  Processing or storing dangerous substances poses a potential threat of fire, explosion or other energy-releasing events.  

The Dangerous Substance and Explosive Atmospheres Regulations 2002 (DSEAR) specify the minimum requirements for protecting people from these risks.

Key Requirements Under DSEAR

Your site needs to:

  • Prepare a suitable and sufficient risk assessment.
  • Eliminate and reduce the risk from dangerous substances.
  • Complete a formal Hazardous Area Classification (HAC).
  • Manage ignition sources within hazardous areas.
  • Establish provision to deal with accidents, incidents and emergencies.
  • Provide information, instruction and training to all relevant personnel.
  • Ensure dangerous substances can be identified on site.

Even without a serious incident that results in damage, injury or loss of life, non-compliance can have serious consequences, with those found in breach of DSEAR subject to heavy fines or even jail time.

Mabbett's DSEAR Services

Mabbett can support operators of all sizes with all aspects of DSEAR compliance - from hazardous area classification and preparing risk assessments to selection of equipment and design of engineering solutions.  Specifically, our consultants and engineers can offer:

  • Risk Assessments to assess the likelihood and consequences of releases associated with the storage and handling of dangerous substances.
  • Preparation of a prioritised action plan to mitigate the risk and develop a Basis of Safety.
  • Preparation of HAC Schedules and Drawing Mark-Ups to indicate extent of hazardous zones.
  • Advice on selection of equipment within ATEX zones, and risk of ignition from mechanical sources such as mixers via Mechanical Equipment Ignition Risk Assessment (MEIRA).
  • Design of engineering solutions.
  • Advice on area signage and labelling requirements.
  • Site-specific DSEAR awareness training.
