the powder spraying device and its hazards. The control
units of the spray guns must be installed and operated
in Zone 22. Spray guns are approved for Zone 21. The
powder spraying device may only be operated by trained
and authorized service personnel. This applies especially
to work on the electrical equipment which may only be
performed by appropriate specialists. Before doing any work
concerning installation, commissioning, setup, operation,
changes in operating conditions and modes of operation,
maintenance, inspection or repair, the necessary shutdown
procedures specified in the operating instructions must be
performed. The powder spraying device is turned off by
using the main switch or, if it exists, by emergency switch
off. The individual components can be switched on and off
during operation by use of the respective switches.
Individual safety instructions for the user company and /
or operating personnel.
1. The user is to refrain from any work which compromises
the technical safety of the powder spraying device.
2. The operator must help to ensure that no unauthorized
persons work on the powder spraying device (e.g. by
installing devices to protect against unauthorized use).
3. The employer must create and operating instruction for
the use of hazardous substances. These instructions
must detail what must occur during handling of
hazardous materials, threats to people and the
environment and the necessary protective measures
and rules of conduct to be followed. These operating
instructions must be written in the language of the
workforce in an understandable form and placed in an
appropriate location known to the workforce.
4. The operator is obliged to check the entire powder
spraying system at least once per shift for apparent
damages and to immediately report any changes
(including in performance) affecting safety.
5. The end user must ensure that the spray powder unit
is only operated in perfect condition.
6. Where necessary, the end user will provide the operator
with protective clothing (e.g. face mask).
7. The user must ensure cleanliness and clarity of the
workspace at and around the powder spraying device.
8. No safety equipment may be disconnected or removed
from service. If the disconnection of safety devices is
required for equipping, repairing or maintaining the
equipment, the safety devices must be reassembled
immediately after the completion of maintenance. All
maintenance activities may only be carried out on a
disconnected powder spraying device.
9. Activities such as controlling powder fluidization,
adjusting high voltage or similar may not be carried
out on an active spray device.
NOTES OF SAFETY HAZARD
Current/Voltage
It is important to reiterate there is an imminent danger to
life through high voltage if shutdown procedures are not
followed correctly.
Energized equipment must not be opened, and the power
plug should not be pulled while energized, otherwise there
is a risk of electric shock.
Powder
Unfavorable powder concentrations in air may ignite in the
presence of sparks. It is the user’s responsibility to ensure
sufficient air in the coating enclosure. Powder lying on the
floor around the powder spraying device constitutes an
imminent risk of slipping.
Static charge
Some possible consequences of static charge are charging
of persons, electric shock or sparks. Charging of objects
and persons must be avoided.
Grounding
All electrically conductive parts in the work area (1.5m
sideways and 2.5 meters in depth by each booth operating
according to DIN VDE 0745 part 10.2) and the work pieces
must be grounded. The resistance to true earth of each
work piece must not exceed 1 Mega Ohm. This resistance
must be checked regularly. Any holders or hangers for the
work piece must ensure the work pieces remain grounded.
If the work piece is suspended, the hanger must be kept
clean so that the necessary conductivity can be retained.
To check the grounding, suitable instruments should be
ready at the workplace.
