Instruction of use for Skydda's protective gloves and arm guards in category III / complex
design
Chemical protection gloves
The gloves are designed for protection against the following risks:
Use of glove
Test results for each model is marked in the glove and/or in its packaging, in our catalogue
and in our web pages.
Basic demands
All Guide gloves is applying to CE directive 89/686 and EN420
Usage
The gloves must be used with caution when risk for contact with machines with moving parts.
CE category 3, protection where there is a high risk for serious injury
EN388 - Protection against physical and mechanical risks.
The figures by the pictogram for EN standard indicate which result the glove has attained in
each test.
The test values are given as a 4-figure code, for example 4112. The higher the figure, the
better the result.
Abrasion (best 4), Cutting (best 5), Tearing (best 4) and Puncturing (best 4)
EN-374 Protection against chemicals and micro-organisms
Scope
This norm specifies the glove's performance concerning the protection of the user against
chemicals and/or micro-organisms.
Definitions Glove lifecycle.
Degradation (deterioration, ageing) has a detrimental effect on one or more elements of the
glove's material.
The speed of degradation depends on the type of chemical the glove has been in contact
with.
Penetration - Penetration means the chemical's and/or micro-organism's route through
porous materials, seams, pinholes
or through imperfections, at a non-molecular level, in the glove's protective film.
Permeation - The glove's protective film in, e.g. natural rubber or plastic is not always a
protective barrier against chemicals. If the surface of the glove is porous it can in certain
cases function as a sponge, absorbing chemicals, and thereby also penetrate
the glove material and reach the skin faster. It is therefore of the utmost importance to
measure the penetration time, or the time it takes for a chemical to penetrate the protection
film and come into contact with the skin.
Measured
• Density: The shortest allowable length that is sealed against liquids is to equal the minimum
length of the gloves as specified in
EN 420.
• Penetration: The glove shall shown no sign of leakage in tests with air and/or water, and
shall be tested in accordance
with an accepted quality level - the so-called AQL level.
Accepted Quality level, AQL Inspection level
Level 3 < 0.65 G1
Level 2 < 1.5 G1
Level 1 < 4.0 S4
The pictogram for chemical protection gloves must display a code consisting of at least 3
letters. These refer to the code letters
for 3 chemicals (from a list of 12 defined standard chemicals - refer to the table below), which
have achieved a penetration time
of a minimum of 30 minutes.
Code Chemical
A Methanol
B Acetone
C Acetone nitrile
D Dichloromethane
E Carbon disulphide
F Toluene
G Diethylamine
H Tetrahydrofurane
I Ethyl acetate
J n-Heptane
K Sodium Hydroxide 40% 1310-73-2
L Sulphuric acid 96%
• Permeation: Each tested chemical is classed according to its permeation time (performance
level 0 to 6)
Measured Permeation time Protection index
> 10 minutes class 1 > 120 minutes class 4
> 30 minutes class 2 > 240 minutes class 5
> 60 minutes class 3 > 480 minutes class 6
The pictogram for "Low chemical protection" or "Liquid seal" must be displayed in cases
where the gloves have not achieved a penetration ti m e of a minimum of 30 minutes against
at least 3 chemicals from the above list, but that meet the requirements of the Penetration
test.
The pictogram for "Micro-organisms" must be displayed when the glove achieves a minimum
of performance level 2 in the penetration test.
We recommend that the gloves are tested and checked prior to use.
The gloves do not contain any known substances that can cause allergic reactions in
normally-sensitive persons.
It is the employer's responsibility together with the user to analyze if each glove protects
against the risks that can crop up in any given working situation.
Detailed information about the properties and use of our gloves can be obtained through your
local supplier or on our websites.
Storage:
Store the gloves in a cool, dry place in their original packaging.
The gloves' properties can be affected by humidity, temperature and strong sunlight.
Disposal:
Dispose of used gloves in accordance with the requirements of each country and/or region.
Cleaning/Washing:
Achieved test levels have been tested and guaranteed on new and unwashed gloves.
The effect of washing on the gloves' protective properties has not been tested.
Cleaning leather gloves: Hand-wash in a mild soap solution. Allow the gloves to air-dry.
