1. Introduction to The Dangerous Substances & Explosive Atmospheres Regulations (DSEAR)

Image of the ATEX and DSEAR -Ex_logoThe DSEA Regulations enact the ATEX Directive in the UK, and were fully implemented in 2006, throughout the EU.

Every Employer/ landfill Site Owner that requires employees to work on a gassing landfill should have a completed and up to date, DSEAR Risk Assessment and have zoned any areas/plant or equipment which is assessed to be at risk from a dangerous substance and/or an explosive atmosphere, in accordance with the regulations.

2. What Needs to be Done for ATEX Directive Compliance (England and Wales)
DSEAR risk assessments should be carried out on all methane stripping plant installations due to the fact that a (normally low) gas explosion risk is present and these risk assessments are required for all plants new and existing.

It is necessary to zone all explosion risk areas within the Methane Stripping Plant, provide information and labelling to identify the zones, train all employees in the safe working methods for the operation of the plant where explosion risks exist, and keep records (possibly as a formal Explosion Protection Document*).

* Requirements vary between EU Member States.

3. ATEX Directive Compliance Requirements Outside England and Wales
Similar Regulations exist in Scotland and Northern Ireland. In the Irish Republic the requirements of the ATEX Directives are implemented under the Safety, Health and Welfare Act (Explosions).

IPPTS Associates offer a DSEAR risk assessment service. Steve Last (Principal of IPPTS Associates) has carried out numerous DSEAR compliance projects for a wide range of clients.
