Technical safety regulations for stationary electrostatic powder spraying equipment
General information
The powder spraying equipment from ITW Gema is designed with safety
in mind and is built according to the latest technological specifications.
This equipment can be dangerous if it is not used for its specified purpose. Consequently it should be noted that there exists a danger to life
and limb of the user or third party, a danger of damage to the equipment
and other machinery belonging to the user and a hazard to the efficient
operation of the equipment.
1. The powder spraying equipment should only be started up and
used once the operating instructions have been carefully studied.
Improper use of the controlling device can lead to accidents, malfunction or damage to the control itself.
2. Before every start-up check the equipment for operational safety
(regular servicing is essential)!
3. Safety regulations BGI 764 and VDE regulations DIN VDE 0147,
Part 1, must be observed for safe operation.
4. Safety precautions specified by local legislation must be observed.
5. The plug must be disconnected before the machine is opened for

Smoking is forbidden in the entire plant area!
12. As a general rule for all powder spraying installations, persons
with pacemakers should never enter high voltage areas or areas
with electromagnetic fields. Persons with pacemakers should not
enter areas with powder spraying installations!
WARNING!
We emphasize that the customer himself is responsible for the safe
operation of equipment. ITW-Gema is in no way responsible for any
resulting damages!
Safety conscious working
Each person responsible for the assembly, start-up, operation, service
and repair of powder spraying equipment must have read and understood the operating instructions and the “Safety regulations”-chapter. The
operator must ensure that the user has had the appropriate training for
powder spraying equipment and is aware of the possible sources of danger.
The control devices for the spray guns must only be set up and used in
zone 22. Only the spray gun should be used in zone 21.
The powder spraying equipment should only be used by trained and authorized personnel. This applies to modifications to the electrical equipment, which should only be carried out by a specialist.
The operating instructions and the necessary closing down procedures
must be followed before any work is carried out concerning the set-up,
start-up, operation, modification, operating conditions, mode of operation,
servicing, inspection or repairs.
The powder spray equipment can be turned off by using the main switch
or failing that, the emergency shut-down. Individual components can be
turned off during operation by using the appropriate switches.
Individual safety regulations for the operating
firm and/or operating personnel
1. Any operating method which will negatively influence the technical safety of the powder spraying equipment is to be avoided.
OptiFlex B manual coating equipment
General safety regulations  5
V 05/10
2. The operator should care about no non-authorized personnel
works on the powder spraying equipment (e.g. this also includes
using the equipment for non-conform work).
3. For dangerous materials, the employer has to provide an operating instructions manual for specifying the dangers arising for humans and environment by handling dangerous materials, as well
as the necessary preventive measures and behavior rules. The
operating instructions manual has to be written in an understandable form and in the language of the persons employed, and
has to be announced in a suitable place in the working area.
4. The operator is under obligation to check the powder spraying
equipment at least once every shift for signs of external damage,
defects or changes (including the operating characteristics)
which could influence safety and to report them immediately.
5. The operator is obliged to check that the powder spraying
equipment is only operated when in satisfactory condition.
6. As far as it is necessary, the operating firm must ensure that the
operating personnel wear protective clothing (e.g. facemasks).
7. The operating firm must guarantee cleanliness and an overview
of the workplace with suitable instructions and checks in and
around the powder spraying equipment.
8. No safety devices should be dismantled or put out of operation. If
the dismantling of a safety device for set-up, repair or servicing is
necessary, reassembly of the safety devices must take place
immediately after the maintenance or repair work is finished. The
powder spraying device must be turned off while servicing is carried out. The operator must train and commit the responsible
personnel to this.
9. Activities such as checking powder fluidization or checking the
high-voltage spray gun etc. must be carried out with the powder
spraying equipment switched on.
Notes on special types of hazard
Power
It is necessary to refer once more to the danger of life from high-voltage
current if the shut-down procedures are not observed. High voltage
equipment must not be opened - the plug must first be taken out - otherwise there is danger of electric shock.
Powder
Powder/air mixtures can be ignited by sparks. There must be sufficient
ventilation in the powder coating booth. Powder lying on the floor around
the powder spraying device is a potentially dangerous source of slipping.
Static charges
Static charges can have the following consequences: Charges to people,
electric shocks, sparking. Charging of objects must be avoided - see
"Earthing".
Grounding/Earthing
All electricity conducting parts and machinery found in the workplace (according to DIN VDE 0745, part 102) must be earthed 1.5 meters either
6  General safety regulations
OptiFlex B manual coating equipment
V 05/10
side and 2.5 meters around each booth opening. The earthing resistance
must amount to maximally 1 MOhm. The resistance must be tested on a
regular basis. The condition of the machinery surroundings as well as the
suspension gear must ensure that the machinery remains earthed. If the
earthing of the machinery includes the suspension arrangements, then
these must constantly be kept clean in order to guarantee the necessary
conductivity. The appropriate measuring devices must be kept ready in
the workplace in order to check the earthing.
Compressed air
When there are longer pauses or stand-still times between working, the
powder spraying equipment should be drained of compressed air. There
is a danger of injury when pneumatic hoses are damaged and from the
uncontrolled release and improper use of compressed air.
Crushing and cutting
During operation, moving parts may automatically start to move in the
operating area. It must be ensured that only instructed and trained personnel go near these parts. The operator should ensure that barriers
comply with the local security regulations.
Access under exceptional circumstances
The operating firm must ensure that local conditions are met when repairs are made to the electronic parts or when the equipment is restarted
so that there are additional measures such as barriers to prevent unauthorized access.
Prohibition of unauthorized conversions and modifications to machines
All unauthorized conversions and modifications to electrostatic spraying
equipment are forbidden for safety reasons.
The powder spraying equipment should not be used if damaged, the faulty part must be immediately replaced or repaired. Only original ITWGema replacement parts should be used. Damage caused by other parts
is not covered by guarantee.
Repairs must only be carried out by specialists or in ITW-Gema workshops. Unauthorized conversions and modifications may lead to injury or
damage to machinery. The ITW Gema GmbH guarantee would no longer
be valid.
Safety requirements for electrostatic powder
coating
1. This equipment is dangerous if the instructions in this operating
manual are not followed.
2. All electrostatic conductive parts, in particular the machinery
within 5 meters of the coating equipment, must be earthed.
3. The floor of the coating area must conduct electricity (normal
concrete is generally conductive).
4. The operating personnel must wear electricity conducting footwear (e.g. leather soles).
5. The operating personnel should hold the gun with bare hands. If
gloves are worn, these must also conduct electricity.

6. The supplied earthing cable (green/yellow) must be connected to
the earthing screw of the electrostatic powder spraying hand appliance. The earthing cable must have a good metallic connection with the coating booth, the recovery unit and the conveyor
chain and with the suspension arrangement of the objects.
7. The electricity and powder supply to the hand guns must be set
up so that they are fully protected against heat and chemical
damage.
8. The powder coating device may only be switched on once the
booth has been started up. If the booth cuts out then the powder
coating device must be switched off.
9. The earthing of all electricity conducting devices (e.g. hooks,
conveyor chains) must be checked on a weekly basis. The earthing resistance must amount to maximally 1 MOhm.
10. The control device must be switched off if the hand gun is
cleaned or the nozzle is changed.
11. When working with cleaning agents there may be a risk of hazardous fumes. The manufacturers instructions must be observed when using such cleaning agents.
12. The manufacturers instructions and the applicable environmental
requirements must be observed when disposing of powder lacquer and cleaning agents.
13. If any part of the spray gun is damaged (broken parts, tears) or
missing then it should not be used.
14. For your own safety, only use accessories and attachments listed
in the operating instructions. The use of other parts can lead to
risk of injury. Only original ITW-Gema replacement parts should
be used.
15. Repairs must only be carried out by specialists and under no circumstances should they be carried out in the operating area. The
former protection must not be reduced.
16. Conditions leading to dangerous levels of dust concentration in
the powder spraying booths or in the powder spraying areas
must be avoided. There must be sufficient technical ventilation
available, to prevent a dust concentration of more than 50% of
the lower explosion limit (UEG) (UEG = max. permissible powder/air concentration). If the UEG is not known then a value of 10
g/m³ should be used.
