DSEAR stands for the Dangerous Substances and Explosive Atmospheres Regulations 2002.

Dangerous substances can put peoples’ safety at risk from fire, explosion and corrosion of metal. DSEAR puts duties on employers to protect people from these risks to their safety in the workplace, and to members of the public who may be put at risk by work activity.



Dangerous substances are any substances used or present at work that could, if not properly controlled, cause harm to people as a result of a fire or explosion or corrosion of metal. They can be found in nearly all workplaces and include such things as solvents, paints, varnishes, flammable gases, such as liquid petroleum gas (LPG), dusts from machining and sanding operations, dusts from foodstuffs, pressurised gases and substances corrosive to metal.


What the law says

DSEAR require employers to find out what dangerous substances are in their workplace and what the risks are.

They must put control measures in place to either remove those risks or, where this is not possible, control them.

Measures must be taken to reduce the effects of any incidents involving dangerous substances.

Plans and procedures must be in place to deal with accidents, incidents and emergencies involving dangerous substances.

Employees must be properly informed about and trained to control or deal with the risks from the dangerous substances.

They must identify and classify areas of the workplace where explosive atmospheres may occur and avoid ignition sources in those areas.
