The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) came into force on 9 December 2002 and applies to all dangerous substances at nearly every business in GB. It sets minimum requirements for the protection of any person, whether at work or not (includes employees, students and the public), from fire and explosion risks arising from dangerous substances and potentially explosive atmospheres. Employers must:

  • Carry out a risk assessment of any work activities involving dangerous substances;
  • Provide technical and organisational measures to eliminate or reduce as far as is reasonably practicable the identified risks;
  • Provide equipment and procedures to deal with accident and emergencies;
  • Provide information and training to employees;
  • Classify and mark places where explosive atmospheres may occur into zones.

DSEAR applies to any substance or preparation (mixture of substances) with the potential to create a risk to persons from energetic (energy-releasing) events such as fires, explosions, thermal runaway from exothermic reactions etc. Such substances include: petrol, liquefied petroleum gas (LPG), paints, solvents, varnishes and certain types of combustible and explosive dusts produced in, for example, machining and sanding operations.

The web addresses for the new Control of Lead at Work and CoSHH Regulations given in January’s “Safetyline” were inaccurate, the ending “html” should have read “htm”.


A recent Court of Appeal case has confirmed that employers have an absolute duty to protect employees from substances hazardous to health as there is no reference in the CoSHH Regulations 1999 to the foreseeability of the risk. Thus in determining whether an employer is in breach of CoSHH it is irrelevant whether the CoSHH assessment (Reg. 6) would have revealed the risk!


Thanks to all of you who returned the Health and Safety self-audit. I have replied by e-mail to most of the queries raised in the returns that required replies. Generally the standard of your responses is good and improving, and the audits we are carrying out will serve to improve them further. I will be reporting the full results to the Health and Safety Committee in February. If any of you feel I have not responded satisfactorily to your return please let me know and I will respond formally.
