ESD S3 SRC HRO

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 Gymkhana Red Bull ESD S3 SRC HRO

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. If you want to buy a shoe of this level but with an anti-puncture midsole then you can choose the S1P version.
  Main features :
  - closed back (even in flat shoes)
  - Antistatic
  - FO: resistance to hydrocarbons of the sole
  - Energy absorption capacity of the heel
  
  
• 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 plate (steel, fabric or Kevlar) to protect the sole of the foot.
  Main features integrated into the basic requirements :
  - Anti-puncture plate
  - Sole with lugs or grooves
  
  
• S4 : this is the most waterproof level ever, with a 100% waterproof level in any external condition and for an unlimited time.
  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
  Main features integrated into the basic requirements:
  - Puncture-proof foil
  - Sole with lugs or grooves

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 :

E = Heel strike shock
A = Electrostatic discharges
WRU = Upper resistant to water absorption and penetration
WR = Overall footwear resistant to water absorption and penetration
P = Perforation
FO = Hydrocarbons
I = Electrically isolated
CI = Cold
HI = High temperatures
C = Electrical conductivity
M = Protected metatarsal
AN = Ankle protected
CR = Cut
HRO = Heat by contact
ESD: Resistance to Electrical Discharges
