JETVARNISH 3D One 3.10 JETVARNISH 3D One Safety Instructions General operating rules Rules related to presence of UV system UV radiation 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. 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. 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 Waste treatment Fire extinguisher Tips and tricks Legislation UV varnish and the cleaning agent bearing a safety sign which warns that eye and skin irritation may occur upon any contact. Residues of UV varnish are chemical residues which shall therefore be transformed by a specialized company. Do not discharge into drains or watercourses Waste and packaging waste must be treated in accordance with federal, state and local environmental regulations. As any machine using elements heating up to more than 70°C, the JETVARNISH 3D ONE shall have a fire extinguisher nearby - adapted Class E (Electrical) fire-extinguisher (CO2 or Powder). "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. 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 Material Safety Data Sheet (MSDS) relating to products or groups of products; the latter contains information in condensed form.
