Keep your workplace safe and compliant under the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR 2002).
What Is DSEAR?
The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) 2002, as amended by the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009, are UK laws designed to protect workers and premises from risks of fire, explosion, and similar hazards caused by dangerous substances.
These substances include flammable liquids, gases, vapours, dusts, and solids that could ignite or explode when mixed with air. Typical examples include fuels, solvents, paints, cleaning chemicals, and combustible dusts often found in workshops, spray booths, laboratories, and production areas.
Why DSEAR Compliance Is Important
Compliance with DSEAR is not optional — it’s a legal duty under:
-
Health and Safety at Work Act 1974
-
Management of Health and Safety at Work Regulations 1999
-
Dangerous Substances and Explosive Atmospheres Regulations 2002
Failure to comply can lead to serious accidents, prosecution, property loss, and business disruption.
A professional DSEAR risk assessment helps identify hazards, implement effective controls, and demonstrate compliance to regulators, insurers, and clients.
At Safety Desk Consulting Ltd, we help businesses across the UK meet DSEAR requirements through expert assessments, practical guidance, and easy-to-understand reports.
What Our DSEAR Risk Assessment Covers
Our comprehensive DSEAR assessment looks at every element of your operation to ensure full compliance and safety.
We assess:
✅ Identification of Dangerous Substances – Reviewing flammable or combustible materials in use or storage.
✅ Process Evaluation – Analysing how substances are handled and where potential release or ignition could occur.
✅ Ventilation and LEV Systems – Checking whether extraction and airflow prevent accumulation of vapours or dust.
✅ Ignition Source Control – Examining electrical systems, static electricity, hot surfaces, and maintenance activities.
✅ Equipment Suitability (ATEX Compliance) – Ensuring machinery and tools are appropriately rated for explosive atmospheres.
✅ Training and Competence – Evaluating staff awareness and emergency readiness.
✅ Fire Protection and Emergency Response – Reviewing alarms, extinguishers, evacuation plans, and spill control.
✅ Cleaning and Maintenance Procedures – Confirming that safe, regular cleaning minimises build-up of hazardous residues.
Hazardous Area Classification (HAC)
A critical part of DSEAR compliance is Hazardous Area Classification.
This defines zones where explosive atmospheres may exist — for example:
-
Zone 0, 1, 2: Gas or vapour hazards
-
Zone 20, 21, 22: Dust hazards
Correct classification ensures that all electrical and mechanical equipment in these zones are ATEX-rated, properly installed, and maintained — reducing the risk of ignition and explosion.
