1
Checking the effectiveness
of technical ventilation
Checking the effectiveness of technical ventila-
tion
TP/SP
ME
Measurements of air flow speed/
air quantities
Check the differential pressure in-
dicator.
Continuously
2
Link between technical ven-
tilation equipment and high
voltage, compressed air and
coating material supply
The technical ventilation should be interlocked
such that the coating material supply and high
voltage cannot be switched on, while the techni-
cal ventilation is not working effectively.
SP
FT
Test whether the system is safely
stopped and the coating material
supply, supply air, and high volt-
age are switched off when the ven-
tilation is shut down.
Annually
3
Parts carrying high voltage
outside the spray area
Parts carrying high voltage outside the spray
area must be routed such that discharges which
put people at risk do not occur.
SP
FT
Inspect and test (e.g., by measure-
ment) whether all parts carrying
high voltage do not result in dis-
charge which puts people at risk.
Weekly
4
Effectiveness of grounding
All conductive components of the system, such
as floors, walls, ceilings, barriers, transport equip-
ment, work pieces, powder tanks, moving de-
vices or structural parts, etc. in the spray area,
with the exception of parts under high voltage
during operation, must be connected to the
grounding system. Parts of the booth must be
grounded in accordance with EN 16985.
SP
VI/ME/CM
Visual check of ground connec-
tions, perform function test on
grounding switch, measurement
of grounding resistors.
Weekly
5
Measures to take if conduc-
tive components are insuffi-
ciently grounded
If sufficient grounding of conductive parts can-
not be ensured, their discharge energy must not
exceed the permissible value.
SP
ME/CM
Measurement of discharge energy.
