IMPORTANT
Garments code 436384 and 436386 must always be worn together. The certified protection is not
guaranteed if the garments are worn individually. The clothing only offers protection for the part of the
body actually covered, therefore it must be integrated, based on the intended use, with suitable per-
sonal protection equipment to protect head, hands and feet. For operational reasons, it is not possible
to provide protection for all the electrically conductive parts of arc welding systems against direct
contact, as the clothing only provides protection against brief accidental contact with live parts of the
arc welding circuit; when the risks of electrocution are higher, additional electro-isolating layers are
requested; the clothing provides protection against brief accidental contact with live electrical wires up
to approximately 100 Vdc. When worn correctly, the clothing protects against normal risks associated
with welding, among which, skin exposure to ultraviolet rays (UV) produced in all electric arc welding
operations, including high intensity UVA, UVB and UVC radiation; the fabric tends to deteriorate with
use; simply inspect this type of clothing (for example weekly) to check protection against UV rays, by
exposing the clothing to the light of a 100-W tungsten lamp at a distance of approximately 1 m; if the
light shows through the fabric, it means that UV rays will penetrate it too. If users perceive the symp-
toms of sunburn, it means that the UVB rays have penetrated the clothing. In each of these cases, the
clothing should be repaired (if possible) or replaced, plus the user should consider the possibility of
using additional protective and more resistant layers in the future.
The outfit only protects against the thermal effects of arc flash caused by accidental and unexpected
short circuits in high power electrical systems with a 4 kA maximum short circuit current (resistance
to flames, resistance to radiating/convective heat, resistance to splashing caused by molten material
debris). The test method employed reproduces arc exposure conditions in low voltage systems (work
near junction boxes, distribution cable cabins, distribution substations) where the arc flash is at the
same height as the worker's sternum. The values obtained from technical tests to check performance
levels are indicated in the PROTECTION LEVELS section. DO NOT wear underclothing made from mate-
rials that could melt due to exposure to arch flashes (polyester, polyamide, acrylic).
The properties of this fabric, offering protection against liquid chemicals, has only been tested with
the reagents listed in the previous table. If there are reagents in the work area different from those
listed you must make certain that the protection clothing is suitable. Its flame propagation limiting
properties could be reduced if it is contaminated by flammable products. The electrostatic charges
are discharged through the user's garment and body. For this reason the user should wear suitable
antistatic footwear (conforming to EN ISO 20345) and the floor or ground must not be an insulator. If
the clothing cannot be in direct contact with the skin of the user, then the clothing must be grounded
with suitable means (ground cable). Resistance between the person and the ground must be less
than 10 Ω. Protective clothing that dissipates electrostatic charges must not be undone or removed
8
in inflammable or explosive atmospheres, or when handling inflammable or explosive substances.
The ability of clothing to dissipate electrostatic charges may be influenced by wear, tear, washing and
contamination. Protective clothing that dissipates electrostatic charges must permanently cover all
materials that do not conform during normal use (including while bending and moving). Clothing with
antistatic properties must not be worn in oxygen enriched atmospheres without the approval of the
Safety Manager. Increased oxygen in the atmosphere noticeably reduces the clothing's protection
against flames. Take care when welding in small spaces if the amount of oxygen in the atmosphere in-
creases. Electric isolation of clothing for welders may be reduced if the clothing is wet, damp or sweaty.
If the user comes into contact with molten iron sprays they must move away and remove the clothing.
If the clothing worn is in contact with the skin it may not eliminate all the risks of burns.The clothing
must never be taken off when the user is still in the work area at risk. In the event of accidental contact
with flammable or liquid chemicals, the clothing must be taken off so that the substances do not touch
the skin; this clothing must then be washed or replaced. The safety characteristics specified are only
ensured if the garment is of the correct size, is worn and secured correctly, and is in perfect condition.
Before use, ensure that the garment is clean and that there are no tears, loose stitching, discoloration
or any other alterations that may be detrimental to its characteristics.
The visibility specifications of the garments are altered if the garments are not sufficiently clean. Pro-
tective properties are altered if unauthorized modifications are made to the garments. Replace the
clothing if it is not perfectly intact (loose stitching, breakages or holes). The manufacturer declines
all forms of responsibility for any damages or consequences deriving from the improper use of the
clothing, or if it has been modified in any way.
NOTES
In the case of manufacturing defects this PPE will be replaced.
