Minimum areas of visible material: 3 classes of garment are specified depending on the minimum
areas of the incorporated materials; class 3 garments offer more visibility in most urban and
rural contexts compared to class 2 garments which are anyway significantly higher than class
1 garments.

The clothing must be cleaned regularly.
The fabric is subjected to anti-acid fluorine-carbon treatment. Wet and dry washing cycles progres-
sively reduce the effects of this treatment. To maintain the declared performance without alterations
it is consequently advisable to refresh the finish by ironing at the recommended temperature or just
with fluorine-carbon agents.
FIELD OF USE
The suit is designed to protect the user against accidental contact with small flames, low convective,
radiant heat and molten iron sprays (EN ISO 11612:2015). The suit is recommended for welders in class
1 suitable for manual welding techniques that involve slight formations of splashes and drips, such
as the following for example: gas welding, TIG and MIG welding, micro plasma welding, brazing, spot
welding, MMA welding (with electrode coated in rutile) and for the operation of oxygen and plas-
ma cutting machines, welders with heating element, thermal spray painting machines and bench
welders. The clothing provides protection against accidental contact with small flames, splashes of
molten metal and brief accidental electrical radiant and contact heat (EN ISO 11611:2015). The suit is
also resistant to chemicals that are not immediately dangerous for one's health and safety, provid-
ing adequate protection against accidental contacts (small splashes, sprays, etc..) which gives the
user time to clean or change the protective clothing (EN 13034:2005 + A1:2009). The electrostatic
properties of this suit ensure that the electrostatic charges accumulated by the user are dissipated
(EN 1149-5:2008) and protects against accidental arc flash risks (IEC 61482-2:2018). Not suitable for
electrical shock risks. The outfit can be worn in scant visibility conditions in any daylight condition
and with vehicle headlights in the dark. Visibility is achieved by the strong contrast between the
garments and the background of the environment where the garment is seen and by the presence of
large areas of high visibility materials (EN ISO 20471:2017).

LIMITS OF USE

The suit, subject of this informative note is UNSUITABLE for use when fighting fire (e.g.: fire fight-
ers),for use where resistance to the permeation of molecular level chemicals is essential or where a
complete barrier is required to liquids and gaseous chemicals. The suit is also UNSUITABLE for any
other uses if they are not mentioned in this briefing note (especially for all those risks grouped in
Category IIII defined by the (EU) Regulation 2016/425).
STORAGE
Store the garment in its original packing in a cool, dry place, away from sources of heat and direct
light. Follow the main tenance instructions mentioned above carefully. These in struc tions are also
given on the garment identification label. Since the suit can be contaminated by chemicals it must
be disposed of in compliance with local laws and regulations on this matter.
