environmental conditions, such as higher mechanical forces, extremely sharp objects,
high and very low temperatures or the inuence of concentrated acids, alkalis or other
chemicals can aect the function of the shoes, and additional safety measures should
be taken.
Shoes with the SB, S1, OB or O1 label should only be worn in dry areas. In wet areas
and in open areas wear the shoes labelled S2 or O2. In places where there is a danger
of penetration from sharp objects (such as nails or shards of glass), a penetration-proof
product with the S3 or O3 label should be worn. We'll be glad to assist you in choosing
the most suitable shoes for you.
Anti-slip: The anti-slip was tested in laboratory conditions according to the parameters
indicated. This does not represent an absolute guarantee for safe walking as this
depends on dierent inuencing factors (for example oor covering, dirt). We
recommend using the system "shoe-oor-medium" in addition to a wearing test on site.
Safety shoes EN 20345:2011 full the demands of an impact with an energy eect of
200 joules and a compressive load of 15 KN to the protective toecap area. These are
base requirements of EN ISO 20345:2011 and rank as protection against falling objects
for category SB, S1, S1P, S2 and S3 items. They do not apply for category EN ISO
20347:2012 OB, O1, O2 and O3 items, which oer no protection against falling objects.
Higher forces can increase the risk of bruising to the toes. In such cases, alternative
preventive measures should be considered.
This footwear's resistance to penetration was ascertained in the laboratory by using a
standardised nail with a force of 1100 N. Higher forces or nails of smaller diameter will
increase the risk of penetration occurring. In such circumstances alternative preventative
measures should be considered.
Two generic types of penetration resistant insert are currently available in PPE
footwear. These are metal types and those from non-metal materials. Both types meet
the minimum requirements for penetration resistance of the standard marked on this
footwear but each has dierent additional advantages or disadvantages including the
following:
Metal: Is less aected by the shape of the sharp object / hazard (i.e. diameter, geometry,
sharpness) but due to shoemaking limitations does not cover the entire lower area of the
shoe.
Non-metal: May be lighter, more exible and provide greater coverage area when
compared with metal but the penetration resistance may vary more depending on the
shape of the sharp object / hazard (i.e. diameter, geometry, sharpness).
For more information about the type of penetration resistant insert provided in your
footwear please contact the manufacturer or supplier detailed on these instructions.
The shoes should be correctly stored and transported, preferably in a box in a dry place.
The shoes are marked with the production month and the production year (for example:
03/2018 = March 2018). An expiry date generally cannot be given, as it depends on
a large amount of inuential factors. 5-8 years from the date of production should be
viewed as a rough guideline. Moreover, the expiry time depends on the level of wear,
use, area of use and other inuential factors such as heat, cold, damp, UV radiation or
chemical substances. For this reason, shoes should always be checked carefully for
damage before use. Damaged shoes must not be worn.
Instruction for assessing a damage: (The images can be found on page 5.)
Use is therefore not permitted.
a) Beginning of marked and deep build-up of cracks over half of the upper material
thickness (see image 1)
b) Heavy wear on upper material, especially when toe caps or toe protection caps are
exposed (see image 2)
c) The upper material shows areas with deformities, burned and melted appearances or
bubbles, or torn-out stitches on the leg (see image 3)
d)
The outer sole shows cracks greater than 10 mm and deeper than 3 mm (see image 4)
e) Separation of upper material / outer sole greater than 10-15 mm long and 5 mm wide
f) Tread depth in deection area of outer sole smaller than 1.5 mm (see image 5)
g) The original inner sole is clearly warped or crushed
h) Destruction of the lining or sharp edges in the toe protection are detected when
checking the inside of the shoe by hand (see image 6)
If shoes have antistatic features, it is essential that the following recommenda-
tions are observed:
Antistatic shoes should be used when there is a need to reduce an electrostatic charge
by discharging the electrical charge so that the risk of sparks igniting ammable
substances or vapors is eliminated, and when the risk of shock from an electrical device
or from live components cannot be completely eliminated. It must be pointed out,
however, that antistatic shoes cannot provide sucient protection against electric shock,
since they only establish resistance between the oor and the foot. If the risk of electric
shock cannot be completely eliminated, other measures must be taken to prevent this
hazard. Such measures and the tests stipulated below should be a part of the routine
accident prevention program in the workplace.
In explosive areas in Zones 0, 1 or 20, and in Zone 21 with substances with an MIE <
3 mJ, shoes capable of discharge, with a personal discharge resistance against the
ground of 10
8
ohms at the most should be worn. Anti-static shoes with an electrical
resistance of > 100 MΩ are therefore unsuitable for these areas.
Experience has shown that, for antistatic purposes, the route through a product should
have an electrical resistance under 1000 MΩ over its entire useful life. A value of 100
kΩ is specied as the lowest limit for the resistance of a new product, in order to ensure
limited protection against dangerous electric shock or ignition from a defect in an
electrical device when working with up to 250 V. It should be noted, however, that the
shoe provides insucient protection under certain conditions, and the wearer of the shoe
