Classification of the safety shoes.

S1 work shoes therefore have at least a safety toecap, but are also antistatic and absorb energy in the heel. Work shoes that meet the s1 classification are most suitable for work in dry conditions.

Just like the S1 shoes, S1P work shoes have a safety nose, but also a safety sole. The shoes are therefore suitable for dry places where sharp objects lie on the ground.

S2 work shoes are the same as S1 work shoes, but also have an increased resistance to water ingress. These safety shoes are therefore suitable for use in humid conditions or in places where it can get damp, such as outdoors.

 

S3 work shoes - are a combination of S1P and S2 shoes. These water-resistant work shoes with a safety toe cap and sole are the most commonly used and ordered, because they are suitable for many working conditions. You don't have to worry if you bump your foot or step into something sharp because your feet are protected.

 

S4 work shoes are again the same as S1 shoes, but the shoes or boots are made of PU, rubber or plastic materials and are therefore waterproof.

 

 

S5 work shoes are the same as S4 shoes, but also have a midsole and a non-slip profile. So these shoes are the safest. SRC - Slip resistant on floors with ceramic tiles, with SLS and steel floors with glycerol and other surfaces.

 

 

SB  - Basic properties (including the toe cap can withstand impacts with 200 J energy and crush up to 15 kN).

SRC - slip resistance on ceramic substrate coated with sodium lauryl sulfate (NaLS) solution, and slip resistance on glycerol coated steel

 

 

Marks that may appear on shoes:

A antistatic footwear

AN ankle protection

C conductive shoes

CI insulation of the cold soil

CR upper cut resistance

E energy absorption in the heel area

ESD electrical resistance between 0.75 - 35 MOhm

FO some resistance to diesel oil

HI insulation bottom against heat

HRO some resistance to contact with hot ground up to 300(±5)°CM metatarsal protection

P soil resistance to perforation with strength 1100 N

SRA slip resistance on ceramic substrate coated with sodium lauryl sulfate solution (NaLS)

SRB slip resistance on steel substrate covered with glycerol

SRC slip resistance on both substrates mentioned above (SRA + SRB)

WR water resistance of all shoes

 

List of Foot Protection Group Standards

 

EN13287
Personal protection. Shoes. Resistance test method for a slip. The standard specifies methods to test the slip resistance of shoes safely, protectively and professionally with the usual soles. Special purpose footwear is excluded from the scope of the standard equipped with spikes, metal pins or other similar elements.

EN14404

Personal protection. Knee pads to work in kneeling position. The standard specifies the requirements that knee pads must meet when working in a kneeling position. There are requirements for the marking of the kneepads and the information to be provided by the manufacturer. The test methods are described and the degree of protection effectiveness is determined. Where protection is declared against additional requirements, protection effectiveness specified in other standards may also apply. Within the range the standard does not include knee pads, these are measures medical or intended for sports purposes.

 

EN20344

Personal protection. Test methods for footwear. The standard specifies methods for testing footwear intended for protection individually. The requirements for the whole also specify footwear, uppers, linings, soles, insoles and soles. This standard can only be used in close conjunction with the EN20345, EN20346 and EN20347 standards, which specify shoe requirements depending on the levels of specific risks.Each type of safety footwear must be marked in such a way indelible and legible - by stamping or marking hot, with the following information: size, number of shoes, type designation according to the manufacturer, manufacturer's trademark, date of manufacture (quarter and year), reference to numbers European standard, the relevant symbol / symbols protective properties or (if applicable), suitable category (SB, S1 ... S5).

 

EN20345

Personal protection. Safe footwear.

The standard defines, in relation to the EN20344 standard, the basic and additional requirements for shoes that are safe for use at work, marked with the letter "S". Footwear defined by the standard must be equipped with a toe cap, which must protect against shocks with the maximum energy level of 200 J and before compression with a force of 15 kN. Details of the footwear division included in this specification can be found in the description of the EN20344 standard.

 

EN20346

Personal protection. Safety shoes. The standard defines, in relation to the EN20344 standard, the basic and additional requirements for safety footwear for use at work, marked with the letter "P". Footwear defined by the standard must be equipped with a toe cap, which must protect against shocks with the maximum energy level of 100J and before compression with a force of 10 kN. Details of the footwear division included in this specification can be found in the description of the EN20344 standard.

 

EN20347

Personal protection. Work shoes. The standard, in relation to the EN20344 standard, defines the basic and additional requirements for professional footwear for use at work, marked with the symbol "OVER". These shoes differ from safety shoes in that they are not fitted with a toe cap to protect against impact and entrapment. Details of the footwear division included in this specification can be found in the description of the EN20344 standard.

 

EN61340-4-3

Static electricity. Standardized Test Methods for Specific Applications - Footwear. The standard provides a method for determining the electrical resistance of footwear used to prevent electrification of the human body, intended for use by both shoe manufacturers and users. The described method of measuring the electrical resistance of the footwear itself is provided as acceptance tests of new footwear. Insulating footwear did not fall within the scope - although the technique of measuring resistance applies to them.

 

 

EN61340-5-1

Static electricity. Protection of electronic devices against static electricity. General requirements. The standard specifies the requirements of adm. and tech. needed to create, implement, and maintain a static protection program. Including the following areas: manufacturing, processing, assembly, installation, packaging, labeling, operation, testing, inspection and other related activities with handling electrical and electronic components, assemblies and devices sensitive to electrostatic discharge with a threshold voltage of 100 V Model Human or larger body. It does not apply to devices with an electrically initiated explosion hazard, flammable liquids, gases and powders.

 

EN381-3

Protective clothing for hand chainsaw users. Test method for shoes. The standard specifies methods for testing the resistance of shoes to chainsaw cuts. The methods for testing the chainsaw resistance of other types of foot and leg protection (e.g. gaiters) are specified in other standards. The scope of the standard only covers shoes with integrated cut protection.

 

EN381-5

Protective clothing for chainsaw and portable chainsaw users. Front leg protection equipment. The standard is one of the standards for individual security measures, intended to protect against hazards when using hand saw chainsaws. NOTE: No security measure can provide 100% protection against cuts caused by a hand chain saw. Nevertheless, experience has shown that it can protective measures that provide a certain degree of protection are produced.A - cut resistance class at chain speed (0-3)X - anti-cutting face type (A, B, C)The circumference of protection for the legs is determined by the three letters A, B, C which is the surface of the material covering the cut protection.

class 0  - 16ms (chain speed)

class 1 - 20ms (chain speed)

class 2 - 24ms (chain speed)

class 3 - 28ms (chain speed)

 

EN17249

Safety shoes resistant to cuts by chainsaws. Requirements are set for safety shoes that are resistant to cuts by chainsaws. Classification, requirements, marking and information provided are discussed. The standard is to be used in conjunction with EN20345, EN20344 and 381-3. The standard excludes certain models of the upper (only models marked with the letters C, D and E are allowed) , with the required minimum top height in model C). In addition, the need to equip footwear with safe toe caps was specified.

 

ESD

Static electricity is a popular ambiguity term for both charge electrostatic (ES) and the phenomena of its formation, accumulation and decay. A special form of E charge decay are discharges electrostatic (ESD - Electro Static Discharge), that is, short pulses of current appear in space between objects with sufficiently large electrostatic potential difference, leading to total or partial decay of the ES charge on these objects.

 

Since the duration of the discharges is relatively short, from a few tens of nanoseconds to hundreds of microseconds, then there are pulses of very high powers, sufficient to ignite explosive atmospheres, damage to workers, damage to semiconductor devices. By Electrostatic hazards is understood the possible possibility that they occur mentioned effects of electrostatic discharges.

The effects of electrification are especially painful in winter, in non-air-conditioned, centrally heated rooms when the relative humidity drops to as much as a dozen percent under extreme conditions. Such conditions, due to significant increase in the resistance (electrical resistance) of materials favor formation and maintenance of electrostatic charges electrification by the material or object in question. Major ones affect the level of risk that arises in the work environment including incorrectly selected means for individual protection. On the one hand, they may not provide enough effective protection for people from external influences static electricity, on the other - they can cause dangerous electrification of his body. *

With shoes that protect against the ESD effect, this prevents electrical charging of the person wearing the shoes, eg through friction when walking on certain surfaces, including preventing dangerous discharges electrostatic. On the other hand, if it is discharged electrostatic or worker contact with high voltage, it thanks to a minimum resistance of 0.75 MΩ the effects are mitigated.

ESD shoes should be used if necessary to avoid electrostatic charging of the worker due to discharge of charges. The occurrence of factors such as climate, degree of pollution, material properties, surface resistance, the structure of the shoe will deteriorate or improve the properties of ESD shoe.
