Safety regulations for Airless
spraying
All local regulations in force must be observed.
For secure handling of Airless high-pressure spraying units
the following safety regulations are to be ob served:
U
Flash point
Danger
Only use coating materials with a flash point of
21ºC or above without additional heating.
The flash point is the lowest temperature
at which vapours develop from the coating
material.
These vapours are sufficient to form an
inflammable mixture over the air above the
coating material.
U
Explosion protection
Danger
Do not use the unit in work places which are
covered by the explosion protection regulations.
U
Danger of explosion and fire from
sources of ignition during spraying
work
Danger
There must be no sources of ignition such as,
for example, open fires, lit cigarettes, cigars or
tobacco pipes, sparks, glowing wires, hot
surfaces, etc. in the vicinity.
U
Danger of injury from the spray jet
Danger
Caution! Danger of injury by injection!
Never point the spray gun at yourself, other persons or
animals.
Never use the spray gun without spray jet safety guard.
The spray jet must not come into contact with any part of the
body.
In working with Airless spray guns, the high spray pressures
arising can cause very dangerous injuries. If contact is made
with the spray jet, coating material can be injected into the
skin. Do not treat a spray injury as a harmless cut. In case of
injury to the skin by coating material or solvents, consult a
doctor for quick and correct treatment.
Inform the doctor about the coating material or solvent used.
U
Secure the spray gun against
unintentional operation
Always secure the spray gun when mounting or dismounting
the tip and in case of interruption to work.
U
Recoil of spray gun
Danger
When using a high operating pressure, pulling the
trigger guard can effect a recoil force up to 15 N.
If you are not prepared for this, your hand can be
thrust backwards or your balance lost. This can lead
to injury.
U
Respiratory protection for protection
against vapours of solvents
Wear respiratory protection when spraying.
The user must be provided with a breathing mask.
U
Prevention of occupational illnesses
Protective clothing, gloves and possibly skin protection cream are
necessary for the protection of the skin.
Observe the regulations of the manufacturer concerning
coating materials, solvents and cleaning agents in preparation,
processing and cleaning units.
U
Max. operating pressure
The permissible operating pressure for the spray gun, spray
gun accessories, and high-pressure hose must not fall short
of the maximum operating pressure of 22.8 MPa (228 bar).
U
High-pressure hose (safety note)
Electrostatic charging of spray guns and the high-pressure hose
is discharged through the high-pressure hose. For this reason the
electric resistance between the connections of the high-pressure
hose must be equal to or lower than 1MΩ.
i
For reasons of function, safety and durability use
only original Wagner high-pressure hoses.
U
Electrostatic charging (formation of
sparks or flame)
Danger
Under certain circumstances, electrostatic charging
can occur on the unit due to the rate of flow of the
coating material when spraying. On discharging this
can result in the emergence of sparks or fire. It is
therefore necessary that the unit is always earthed
through the electrical installation. The unit must
therefore always be earthed via the carriage frame.
