ATEX Industrial Risk
ATmosphère Explosible» or Exposible Atmosphere (or potentially explosive atmosphere)
is a mixture with air, under atmosphere conditions, of flammable substances in the form of gases, vapours, mists or
dusts, after ignition has occurred, combustion spreads to the entire unburned mixture.

How to protect yourself from explosions?
According European directive 1999/92/CE
1) Hazard identification
2) Assessment of explosion risks
3) Classification of hazardous places
4) Adequacy of work equipment
5)Training of workers
6) Draw up and keep up to date an Explosion Protection Document
15
How to protect yourself from explosions?
1) Identification of risks
2) Risk assessments
According European directive 1999/92/CE
identification and careful examination of the dangerous substances present or liable to be present in the workplace
the work activities involving them The hazardous properties of the substances; The way they are used or stored; The possibility of hazardous explosive atmospheres occuring All potential ignition sources
&
16
How to protect yourself from explosions?
According European directive 1999/92/CE
3) Classification of ATEX areas Location where an explosive atmosphere can be occur
Zones 0 et 20
Location where an ATEX is present permanently, for long periods or frequently.
Zones 1 et 21
Location where an ATEX is likely to Occasionally Occur in Normal Operation.
Zones 2 et 22
Location where an ATEX is not likely to occur in normal operation or, if it present, it is only of short duration (malfunction).
Determination by measure
Determination by the eye
The flat-rate determination
Modeling determination
Methods of determination
17
The points of entry to zones must be marked with the following warning sign:

1) To avoid ATEX area :
Substitution of flammable substance,
Inerting,
Test sealing
Leak detection,
ventilation,
Cleaning of dust…
2) To avoid of ignition source:
Protection modes,
Equipotential connections.
3) Limitation of the effects of an explosion :
Explosion events,
Flame arrest, ....
