ATEX European directions
What does ATEX mean?
ATEX is the name of two European Directives that control potentially explosive atmospheres. The
first, 94/9/EC, prescribes the minimum safety and health requirements of equipment and protective
systems intended for use in potentially explosive atmospheres and is aimed at manufacturers. This
directive has the task of bringing together the legislation in Member States for equipment and
protective systems for these risk areas. The second, 99/92/EC, prescribes the minimum safety and
health requirements of workers exposed to the risks of explosive atmospheres.
What is an explosive atmosphere?
An explosive atmosphere is one that may become explosive due to the local and working
conditions. It is defined as a mixture of air and inflammable substances in the form of gases,
vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire
unburned mixture.
What does the directive apply to?
Equipment and protective systems intended for use in explosive atmospheres.
Safety, control and monitoring devices that contribute to the safety operating of equipment and
protective systems.
All electrical, mechanical, hydraulic and pneumatic equipment.
What are the user’s obligations?
With regard to the prevention of explosions and relative protection, users are obliged:
to take suitable technical or organizational measures depending on the type of control
globally assess the risks of explosion
divide up the areas in which explosive atmospheres may occur
indicate areas defined as dangerous
Which zones and which hazards?
Zone 0 for gas (or 20 for dust):
a place in which an explosive atmosphere is present
continuously or for long periods
Zone 1 for gas (or 21 for dust):
a place in which an explosive atmosphere is likely to occur
during normal operating
Zone 2 for gas (or 22 for dust):
a place in which an explosive atmosphere is likely to occur
during normal operating and if it does occur, will persist for a
short period only
How to check for compliance?
Equipment of components that comply with the directive must bear the CE mark and the special
marking described below:
