JETVARNISH 3DS 2. Security and Safety Rules
Technical Manual - 14 -
2.8 JETVARNISH 3DS Safety Instructions
General operating rules
For safety reasons, always disconnect power connectors prior to performing
any maintenance or repair operation. Any person authorized to intervene shall
be called for any important setting or repair operations, especially for electrical
repair purposes.
Handling UV varnish and cleaning agent require the following rules to be
complied with in order to prevent any risks to health: Refer to MSDS
–
Material Safety Datasheet: Steps 2 - 7 - 8 - 15, delivered together with the
consumables.
Rules related to presence of UV
system
The use of UV systems may entail a few risks. These risks are eliminated
when these systems are used under normal circumstances. The risks to
humans when using UV systems are the following:

Skin and eye exposure to UV radiation.

Contact between skin, eyes and UV varnish.

As regards the environment, two elements have to be taken into account:
UV varnish and UV LED.
UV radiation
Exposure to UV radiation causes skin and eye injury. High doses cause
sunburns. As eyes are the most sensitive to UV radiation, it is recommended
to not directly look at a UV LED. The symptoms are actinic conjunctivitis and
snow blindness. Although such disorders may be very painful, they disappear
without leaving permanent damage. A good UV system features a device
which masks direct radiation of the lamp or reflectors through protective plates
and narrow beam.
UV varnishes and cleaning
agent UV varnish and the cleaning agent bear a safety sign which warns that eye
and skin irritation may occur upon any contact.
Waste treatment
Residues of UV varnish are chemical residues which shall therefore be
transformed by a specialized company.
Safety - Fire extinguisher
As any machine using elements heating up to more than 70°C, the
JETVARNISH 3DS shall have a fire extinguisher nearby.
Tips and tricks
"Post curing" (that could be termed delayed drying) is a well-known
phenomenon in UV printing processes. It is recognized that, regardless of the
power of the UV LED used for drying, the polymerization reaction is not
complete. It is therefore better to wait for 24 hours prior to performing any
finishing (cutting or scoring) or lamination operation. As regards glossy
varnishes, it is also better to wait for 24 hours before delivery in order to
prevent any fingerprints during handling.
Legislation
Industrial safety legislation concerning control of hazardous materials makes
the user fully responsible for safety during use and application of inks; this
includes by-product treatment and waste disposal. The ink supplier's
responsibility consists in transmitting Safety Datasheets relating to products or
groups of products; the latter contain information in condensed form.
Safety perimeter
For more safety, a 60cm perimeter around the JETVARNISH 3DS is
recommended; as a rule, the freer the direct area around the machine, the
less substantial the risks in terms of both pallet size and chemical products. It
is prohibited to place chemical products inside the machine, except at the
specific locations -replacement of ink container-.
Recommendations
It is highly recommended not to have flammable materials around the
machine; 1 meter clearance all around the machine allows for safe working.
For user convenience, it is recommended to have an air renewal system.
As a matter of fact, the JETVARNISH 3DS operates together with UV LED
which release heat, and the ambient temperature may rise at the end of the
day.
