1.2.4 Protective breathing masks
Although the E-Static AirCoat spraying procedure produces very little mist, it is
not completely mist free. There are, in fact, few paint particles to be found in
the air. Nevertheless, the operator must use a protective breathing mask, (see
respiratory equipment instruction sheet ZH 1/134 and VGB 23 from the
professional trade association) during spraying operations.
1.2.5 The spray gun and the high pressure hoses between the pump and the
spray gun must be of a sufficient quality for the pressure produced by the
pump.
A permanent marking on the high pressure hoses must indicate the maximum
permitted working pressure, the manufacturer and date of production.
Furthermore, it must be of a suitable quality so that the electric resistance
between the pump connection and the spray gun is less than 1 megaohm.
1.2.6 Earthing
Depending on the electrostatic charge and the flow speed of the spray an
electrostatic charge may, in certain cases, occur on the equipment. This could
cause a spark or flame on discharging. In order to avoid this the equipment
must always be earthed.
There must be a conductive connection (potential equalisation cable) between
the material container and the equipment.
All persons within the working area must wear shoes with electricallyconductive
soles (e.g. shoes with leather soles). Gloves must also be conductive, because
the operator is earthed through the handle of the spraygun. The floor of the
working area must be conductive, in accordance with VDE 0745, part 1,
paragraph 35: measurements according to DIN 51953.
1.2.7 Extraction systems
Paint mist extraction systems must be fitted on site according to the local
regulations.
1.2.8 Accessories and spare parts
The manufacturer's guarantee and product liability are only valid if original
Wagner accessories are used.
1.2.9 Safety information on harmless electrostatic discharges
If the plastic parts of the spray gun are touched with the hand this can result in
a harmless discharging (so-called brush discharge). The same occurs when
you electrostatically charge yourself by walking on a synthetic carpet and then
touch a metallic door handle, thus discharging the electrostatic charge. The
charge on the plastic parts is caused by the high-voltage field of the gun. The
discharging is completely safe for people and is not able to cause any ignition.
A corona glow may occur at the electrode end of the gun when it is in use (only
visible under dark conditions). A corona discharge can occur if the electrode
(spray gun) comes within a distance of 4 - 10 mm from the object being spray-
ed. The corona glow does not cause any ignition hazard.
