Dangerous Substances and Explosive Atmosphere Regulations (DSEAR)

The Dangerous Substances and Explosive Atmospheres Regulations set minimum requirements for the protection of workers from fire and explosion risks related to dangerous substances and potentially explosive atmospheres in the workplace. DSEAR is the ‘framework’ adopted by the Health & Safety Executive (HSE) to facilitate compliance to ATEX 137 within the UK.

It’s the responsibility of the employer to minimise the risks to their employees that can result from potentially explosive atmospheres (i.e. where there is presence of gases, vapours, liquids or dusts). DSEAR calls upon several requirements to facilitate this:

  • Conduct risk assessments of non-electrical equipment already installed on-site
  • Carry out competent risk assessments on any work activities involving dangerous substances
  • Provide equipment and procedures to deal with accidents and emergencies
  • Provide instruction and training to employees
  • Classify the site into zones of risk (Area Classification)
  • Use appropriate (certified) equipment in hazardous areas
  • Co-ordinate the site health and safety for all users of the site, including sub-contractors, maintenance crews, security staff etc

Our Fire Safety and DSEAR experts have expertise in operation, production or maintenance for blue chip companies in the process industry, and as such are aware of the practical difficulties and constraints of implementing new legislation. We can therefore offer pragmatic and practical solutions to DSEAR problems.
