EXPLANATION OF ATEX
1. Assess their products to prevent creation of an explosive at-
mosphere or a source of ignition of an explosive atmosphere.
2. Certify that when the products are properly installed, main-
tained and used for their intended purpose, they do not en-
danger the health and safety of persons, animals or property.
The ATEX Directive recognizes that the probability of a serious
event occurring varies with:
The explosive properties of the atmosphere.
The probability of the atmosphere being present.
The probability of the machinery causing an explosive atmo-
sphere.
The probability of the machinery causing an ignition source.
The ATEX Directive recognizes the need for special conditions of
installation, operation and maintenance that must be followed to
reduce or eliminate this potential for a serious event.
The ATEX Directive requires a completed machine to be marked
to indicate that the completed machine has been certifi ed for use
in potentially explosive atmospheres and to inform users of limits
and special conditions of use.
