A Quick Guide to DSEAR
What is DSEAR?

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

Dangerous substances can put peoples’ safety at risk from fire and explosion. DSEAR puts duties on employers and the self-employed to protect people from risks to their safety from fires, explosions and similar events in the workplace, this includes members of the public who may be put at risk by work activity.

What are dangerous substances?

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. 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 and dusts from foodstuffs.

What does DSEAR require?

Employers must:

Find out what dangerous substances are in their workplace and what the fire and explosion risks are

Put control measures in place to either remove those risks or, where this is not possible, control them

Put controls in place to reduce the effects of any incidents involving dangerous substances

Prepare plans and procedures to deal with accidents, incidents and emergencies involving dangerous substances

Make sure employees are properly informed about and trained to control or deal with the risks from the dangerous substances

Identify and classify areas of the workplace where explosive atmospheres may occur and avoid ignition sources (from unprotected equipment, for example) in those areas.
