The use of Personal Protection Equipments (PPE) with CE mark (that is, in compliance with the requirements of harmonized Norms EN 345-1, EN 345-2, EN 20345:2004, EN 347-1, EN 20347:2004)  is compulsory by law as designated by the European Directive 89/686/EEC.
Using comfortable Personal Protection Equipments as
COMFORTABLE SAFETY SHOES by BASE Protection
to wear trouble-free for at least 8 hours a day is a PROFESSIONAL CHOICE certified by the notified body:

CIMAC
c/so Brodolini, 19
27029 Vigevano (PV)
N. 0465

The responsibility in the choice of a PPE is a duty of the employer, who will evaluate the distinctive risks of damage in his work environment, in order to adopt the necessary measures for prevention and safety and to choose then the right footwear for his class of risk.
In any case we suggest the user to verify the features of the shoes before wearing them.
Ergonomy  is an essential factor of choice.

The minimum requirements are (values measured on size 42):
- bump  resistance with impact energy 200 Joule, minimum residual height after bump must be ≥ 14  mm (on size 42).
- crush resistance for compression of the toe cap with a strength of 15 KN (15 KN = 1,5 ton ca)

There are, as pointed out by specific markage hereafter:

Safety category Characteristics of the shoes
EN 20345
SB                   Basic requirements
S1                           SB + Heel region closed, antistatic properties, energy absorption in the heel region
S2                           S1 + resistance to water penetration and absorption of the upper

O1                                            OB + Heel region closed, antistatic properties, energy absorption in the heel region
O2                                            O1 + resistance to water penetration and absorption of the upper
O3                                            O2 + resistance to perforation of the shoe bottom, sole with relieves

SLIP RESISTANT
SRA Ceramic and detergent solution
SRB Steel and glycerol
SRC (Slip Resistant C type ) = SRA+SRB

Before using the shoes it is fundamental to verify:

The integrity of the sole;
Correct closing;
Presence of steel toe cap and midsole (if expected)
HOW TO CLEAN THEM
Use soft brushes and water. NEVER use such materials as alcohol, diluents, petrol or any other chemicals.
Keep your shoes, dry and clean, in an appropriate place in room temperature.
Wet shoes should never be put directly into contact with warm sources after use, but left to dry up in an airy place in room temperature.

Antistatic footwear are marked A, S1, S2, S3, O1, O2, O3.
Antistatic footwear should be used when it is necessary to reduce the build up of electrostatic charges by dissipating them, thus avoiding the risk of fire. This is possible for example with inflammable substances and vapours in the case the risk of electric shocks deriving from electrical appliances was not completely eliminated.
However, antistatic shoes cannot guarantee a complete protection against electric shocks since they only insert a resistance between foot and ground.
If the risk of electric shocks was not completely eliminated, it is essential to resort to additional countermeasures.
These measures, together with further tests listed hereafter, should be integrated with the prevention program carried on in the workplace.
To antistatic purposes, the discharge pathway through a product should have, in normal conditions, an electric resistance lower than 1.000 MW in any moment of the product’s life.
A value of 100 KW  is defined as lower limit of resistance for a brand new product, in order to assure a certain protection against dangerous electric shocks or against fire, in the case an electric appliance shows defects when working up to 250V.
However, in certain conditions, users should be informed that the protection supplied by the footwear could be ineffective and that other methods have to be adopted to protect the user in any moment.

SHOULD THEY BE USED IN A PARTICULAR WAY?

The electric resistance of this kind of shoes could significantly vary depending on bending, contamination or humidity.
This kind of shoes will not work properly if worn and used in wet environments.
It is therefore necessary to be sure that the product can keep its function to dissipate electrostatic charges and give a certain protection during its whole life.
We recommend the user to make an electrical resistance test on the place and use it on a regular basis.
If the shoes are used in such conditions, so that the sole material is contaminated, users should always verify its electrical properties before entering a risk area.
During the use of antistatic footwear, resistance of the ground should be such, not to eliminate the protection offered by the shoes.
During use it is essential to keep insock  and sole in good condition. NEVER insert any material between insole and foot. In the case an insole is introduced between insock and foot, it will be necessary to verify electrical properties of the combination shoe/insole.
