DSEAR / ATEX Risk Assessment / Area Classification / Compliance


The control of flammable substances either in Gas/Vapour or Dust form is key in any industry, whether in the Process Sector or indeed Food and Drinks Sector.  

What is DSEAR?

DSEAR stands for the Dangerous Substances and Explosive Atmospheres Regulations 2002.

Dangerous substances can put peoples’ safety at risk from fire and explosion. DSEAR puts duties on employers and the self-employed to protect people from risks to their safety from fires, explosions and similar events in the workplace, this includes members of the public who may be put at risk by work activity.

For more detailed information on DSEAR please consult the HSE Website, Section on DSEAR 


What is ATEX?

ATEX is the name commonly given to the framework for controlling explosive atmospheres and the standards of equipment and protective systems used in them.

It is based on the requirements of two European Directives.

1) Directive 99/92/EC (also known as ‘ATEX 137’ or the 'ATEX Workplace Directive’)

2) Directive 94/9/EC (also known as ‘ATEX 95’ or ‘the ATEX Equipment Directive’)
