Changes to DSEAR (Dangerous Substances and Explosive Atmospheres Regulations) 2002

Substances classified under DSEAR are those that present a risk from fire and explosion from being present or used on site. Obvious examples would include, solvents, some paints and varnishes but the definition also covers dust and gases which can be flammable. However, now substances which are corrosive to metal and pressurised gases are newly covered under DSEAR.

Under DSEAR employers must identify any dangerous substances and potentially explosive atmospheres, assess the risks and put in place appropriate control measures if those risks cannot be eliminated. They must also prepare plans to deal with accidents involving those substances and ensure staff are informed and trained in those plans.
