Eco Safety Shoes
ESD S3S SR LG

Guide to the correct interpretation of protection classes and standards

* highlighted it is possible to identify the characteristics that distinguish the shoes in question Sparco Indy-e Forester ESD S3S SR LG.

All safety shoes for professional use compliant with EN ISO 20345:2022 are characterized by the following words:

• S : Safety Shoes (from the English word Safety)
• B : when the letter S follows, it indicates Basic protection. These Mandatory Basic Requirements include the minimum indications to be respected regarding:
  • the height of the "split" leather upper which can also be opened in the heel area
  • the minimum length and supporting base of the tip
  • similar microfibre
  • front lining
  • insole
  • sole that can be made of any type of material.
• P: Protection shoes with protective toe cap (from the English word Protection) safe against impacts with energy of 100 J and compression 10 kN

As regards foot protection, footwear classified as "S" is further divided into:

• SB : is the basic protection level, less protective than the other levels and is equipped with a 200 Joule steel toe cap to protect the fingers, meeting the main safety requirements of the EN 345 standard.
  
  
• S1 : S1 level shoes, in addition to the steel toe, also have an antistatic sole with energy absorption in the heel area. The shoes falling into this category are suitable for workers who are not particularly at risk and do not foresee risks for the sole of the foot as this area does not have an anti-puncture plate. They are divided into:
  S1: They do not have anti-puncture plate
  S1P: They have anti-perforation steel plate
  S1PL: They have Metal Free anti-perforation plate for 4.5 mm nails (Large)
  S1PS: They have Metal Free anti-perforation foil for 3 mm nails (Small)
  
  
• S2 : this level, in addition to the characteristics of the S1, also has a slight waterproofness given by a leather upper (or similar materials) capable of resisting water permeability for max. 60 minutes.
  Main features integrated into the basic requirements :
  - Dynamic waterproofing of the upper material
  
  
• S3 : this is the most widespread level and combines the characteristics of the S1 and S2 levels (steel toe cap and waterproofness) in a single shoe, however adding the anti-puncture midsole and is divided into:
  S3: They have anti-perforation steel plate
  S3L: They have Metal Free anti-perforation plate for 4.5 mm nails (Large)
  S3S: They have Metal Free anti-perforation plate for 3 mm nails (Small)
  
  
• S4 : this is the most waterproof level ever, with a 100% waterproof level in all external conditions and for an unlimited time (WRU).
  Main features integrated into the basic requirements :
  - Antistatic
  - Energy absorption from the heel
  - FO resistance to hydrocarbons
  
  
• S5 : is the version of S4 with the addition of the anti-perforation plate
  They are divided into:
  S5: They have anti-perforation steel plate
  S5L: They have Metal Free anti-perforation plate for 4.5 mm nails (Large)
  S5S: They have Metal Free anti-perforation plate for 3 mm nails (Small)
• S6 : EXTRA water resistance (WR) and are divided into:
  S6: They do not have anti-puncture plate
  S6P: They have anti-perforation steel plate
  S6L: They have Metal Free anti-perforation plate for 4.5 mm nails (Large)
  S6S: They have Metal Free anti-perforation plate for 3 mm nails (Small)
  
  
• S7 : S6 + anti-perforation plate. They are divided into:
  S7: They have anti-perforation steel plate
  S7L: They have Metal Free anti-perforation plate for 4.5 mm nails (Large)
  S7S: They have Metal Free anti-perforation plate for 3 mm nails (Small)

Slip resistance classes

Also regarding the anti-slip level of work shoes we have three different classes all complying with the EN 13287 (2012) standard:

• SRA : slip resistance with ceramic floor with water and detergent
• SRB: slip resistance with steel and glycerine floor
• SRC: slip resistance with both of the above conditions

Shoe classification based on risk assessment

The potential risks prevented by safety shoes are also characterized by acronyms that identify which risk protection is ensured from :

P: Puncture resistant foil
E: Energy absorption from the heel
WR : Water Resistance (it is the improvement of the WRU)
WRU/WPA: Upper resistant to water penetration from 2023
AN: Ankle protection
M: Metatarsal Protection
HRO: Sole resistant to contact with heat 300°C for 1 minute
HI: Heat insulation up to 150°C
CI : Cold insulation down to -17°C
FO: Hydrocarbon resistant sole
ESD: Protection from electrical discharges
A: Electrostatic shoe
C: Conductive shoe (electricity)
CR: Cut Resistance
SRA: Slip resistance with ceramic floor with water and detergent
SRB: Slip resistance with steel and glycerine floor
SRC: Combination of SRA + SRB
DGUV112-191: Orthopedic insole adaptation
SC: Tip abrasion resistance
LG: Sole with heel detached from the sole for grip on ladder rungs
