What is DSEAR?
The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) place a legal duty on employers and the self-employed to protect people from the risks of fire, explosion and similar events caused by dangerous substances in the workplace. A DSEAR assessment identifies those substances, evaluates the risks and sets out the measures needed to control them.
Dangerous substances covered by DSEAR include:
- Flammable liquids — petrol, solvents, paints and thinners
- Flammable gases — LPG, acetylene, hydrogen and natural gas
- Combustible dusts — wood, flour, sugar, metal and other fine powders
- Oxidising and other substances that can create a fire or explosion risk
Your Duties Under DSEAR
Where dangerous substances are present, DSEAR requires you to:
- Assess the risks: Identify the dangerous substances on site and the fire and explosion risks they present.
- Eliminate or reduce risk: Remove the hazard where possible, or put control and mitigation measures in place.
- Classify hazardous areas: Zone any places where explosive atmospheres may occur and select suitable, correctly rated equipment.
- Prepare for emergencies: Provide information, instruction and training, and put arrangements in place to deal with accidents and incidents.
Who Needs a DSEAR Assessment?
A DSEAR assessment is essential for any business that stores, handles, uses or produces dangerous substances, including:
- Manufacturing, engineering and processing sites
- Fuel storage, forecourts and chemical stores
- Food and drink production, where combustible dusts or alcohol are present
- Paint, coating, print and woodworking operations
- Laboratories, pharmaceutical and healthcare facilities
