ATEX 137 and DSEAR

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) sets 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. Other European countries will not adhere to DSEAR specifically, however, there will be similar frameworks in place as a vehicle towards ATEX 137 compliance.

Responsibilities and Requirements of DSEAR

It is 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 site health and safety for all users of the site, including subcontractors, maintenance crews, security staff etc.

Our team of DSEAR experts have backgrounds in operation, production or maintenance in the process industry, and as such are aware of the practical difficulties and constraints of implementing legislation.
