Footwear

A number of hazards threatening the user’s health and/or safety can be identified :
• Mechanical hazards : impacts, crushing, perforation…
• Chemical hazards: hazardous or corrosive products…
• Heat-related hazards: cold, heat, weather, molten metal projections …
• Electric hazards: electrical discharge, static electricity
• Hazards related to radiation and contamination: ultraviolet
• Biological hazards: allergies, irritations…
• Hazards related to the user’s movements: skidding…
The materials used for those products are broken down into
two classes:

** Class
Class 1: all leather and other materials (except for all rubber or all polymer)
Class 2: all rubber (fully vulcanised) or all polymer (fully moulded)
 


STANDARDS

There are 3 categories of shoes for professional use.

EN ISO 20345 : Specifications for safety footwear for professional use
Toe protection against shocks equivalent to a level of energy equal to 200J and the risks of flattening under a maximal weight of 1500 daN.

EN ISO 20346 : Specifications for protective shoes for a professional use
Toe protection against shocks equivalent to a level of energy equal to 100J and the risks of flattening under a maximal weight of 1000 daN.

EN ISO 20347 : Specifications for occupational footwear for professional use
No specification about toe protection..

EN ISO 20344 :
Test methods for footwear



Besides of the general requirements, the shoes may comply with additional facultative requirements;

examples:
- shoes with steel midsole: symbol «P»
- heel energy absorption: symbol «E»


Categories identifiable by a code group combinations gather most of common requirements.

Examples:

- Symbol “S1” = EN ISO 20345 basic properties + closed back + anti-static  properties + heel energy absorption + resistance to fuel oil

- Symbol "S2" = S1 + water penetration and water absorption.


- Symbol “S3”  = S2 + penetration resistant sole + studded sole



Determination of slip resistance:


Marking SRA: Slip resistance on ceramic tile floor with SLS


Marking SRB: Slip resistance on steel floor with glycerol.


Marking SRC: SRA + SRB
