Safety footwear symbols
Charnwood
At Charnwood, we manufacture and distribute robust, durable footwear and workwear, designed to be comfortable all day long. We have a wide range of footwear on offer, with varying styles and designs, all suitable for a number of different industries and working environments.
The different safety features on our footwear are represented by a number of symbols, which you can find in the product description section of each pair of shoes:
In this article, we will be running through the symbols and explaining a little more about what they mean, so you can make the right selection when purchasing your next pair of safety footwear.
Our range here at Charnwood is designed in line with The Safety Footwear Standards, set by the ISO. Standing for International Organisation for Standardisation, the ISO publishes set standards for a huge number of industries, including medical devices, energy, security, and of course of most importance to us at Charnwood, safety footwear.
The "EN" before ISO simply refers to the European Union. When an international standard is recognised at a regional level, a prefix can be added, hence EN ISO.
There are various reference numbers to differentiate between standards:
EN ISO 20345: 2004 - refers to all safety footwear designed before 2004 that is still being manufactured today.
EN ISO 20345: 2007 - refers to all safety footwear designed, manufactured, and retested after 2007.
Both of these set out minimum requirements that safety footwear must be successfully tested against.
EN ISO standards specify that all safety footwear must have toe protection as standard. In addition to this, further protective features for safety footwear are represented by a combination of letters.
S1: Safety Basic, Antistatic, and Energy Absorbing Heel.
S2: Safety Basic, Antistatic, Energy Absorbing Heel, and Water Resistant Upper.
S3: Safety Basic, Antistatic, Energy Absorbing Heel, Water Resistant Upper, and Steel/Composite Midsole.
S4: Safety Basic and 100% Waterproof Upper.
S5: Safety Basic, 100% Waterproof Upper and Steel/Composite Midsole.
S1P: Safety Basic, Antistatic, Energy Absorbing Heel, and Steel/Composite Midsole.
SB: Safety Basic to EN345 200 Joule Toe Protection.
SBP: Safety Basic and Steel/Composite Midsole.
P1: Protective Basic and Antistatic.
PB: Protective Basic to EN346 100 Joule Toe Protection.
Slip Resistance Ratings
Footwear has to pass the EN test for slip resistance in order to be marked with one of the following codes:
SRA: tested on ceramic tile surface with diluted soap solution.
SRB: tested on smooth steel with glycerol.
SRC: tested on both of the above.
Additional Symbols and Their Meanings
P: penetration resistance
C: conductive
A: antistatic
I: electrically insulating
HI: insulating against heat
CI: insulating against cold
E: energy absorbing seat region
WR: whole footwear resistant to water penetration and absorption
M: metatarsal protection
AN: ankle protection
WRU: water resistant upper only
CR: cut resistant upper
HRO: outsole resistant to hot contact
Please note that the above is for guidance only. Regulations and standards are constantly updated and reviewed. We always advise that customers seek independent advice and where possible, conduct a risk assessment to determine the type of safety footwear they need.
All our safety shoes and boots are displayed with symbols to make it easier for you to select your next pair.
