3.2 Use of Tools in Ex Zones
The spray booth is classified once into ex zones according to
UNI EN 16985:2019
. Ex zones are
defined beforehand and are effective independently of the installation's operating condition. Even
a sufficiently ventilated spray booth which does not contain any inflammable material is still
considered as ex zone.
According to DIN EN 50176, only accessories meeting the requirements of EN 60079-0 and/or
EN13463-1 can be used in an ex zone.
UNI EN 16985:2019
always requires a technical ventilation inside the spray booth. Spray booths
with fresh air inlets are provided a sufficient ventilation after 3 to 10 air exchanges. As a rule, the
spray booth is sufficiently ventilated after 5 minutes. In air recirculation installations, a ventilating
time of 30 minutes
[4]
is necessary to achieve a sufficient ventilation, depending on the mixture
ratio of recirculating air to fresh air.
The use of not classified tools pursuant to the regulations for protection against explosions in
hazardous areas is the customer's exclusive responsibility.
-
The
customer
has to carry out a risk assessment for every operation performed, to document
them and to prepare an operating manual on the basis of the resulting evaluation.
-
The
customer
has to ensure that all operators carrying out their own respective tasks know
and observe these measures.

This value is dependent on the design and settings and must always be determined on the basis
of the system-specific parameters.
