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.
2. The operator is under obligation to check the powder spraying equipment at
least once a month for signs of external damage, defects or changes
(including the operating characteristics) which could influence safety and to
report them immediately.
3. The operator is obliged to check that the powder spraying equipment is only
operated when in satisfactory condition.
4. As far as is necessary, the operating firm must ensure that the operating
personnel wear protective clothing (e.g. facemasks).
5. The operating firm must guarantee cleanliness and an overview of the
workplace with suitable instructions and checks in and around the powder
spraying equipment.

Notes on special types of hazard
3.4.1 Power
High voltage equipment must not be opened - the plug must first be taken out – otherwise
there is the danger of electric shock.
3.4.2 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.
3.4.3 Static
charges
Static charges can have the following consequences: Charges from people, electric shocks,
sparking. Charges from objects must be avoided – see Earthing
3.4.4 Earthing
All electricity conducting parts and machinery found in the workplace (according to DIN VDE
0745, Part 102) must be earthed 1.5 m either side and 2.5 m around each booth opening.
The earthing resistance of each piece of machinery must amount to 1 M
Ω
. 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 this must constantly be kept
clean in order to keep the necessary conductivity. The appropriate measuring devices must
be kept ready in the workplace in order to carry out the testing.
3.4.5
Compressed air
When there are to be longer pauses or stand-still times between working then 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.
3.5
Prohibition of unauthorized conversions and modifications to equipment
All unauthorized conversions and modifications to powder 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 ITW-Gema 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
modifications can lead to personal injury and damage to machinery. The ITW Gema AG
guarantee would no longer be valid.
