Occupational Safety Shoe Symbols

Common symbols used within the scope of Occupational Safety Shoe standards are as follows;

P : Steel midsole (permeability resistance up to 1100 kgs)
C : Conductive Shoe (electrical resistance up to 100 KiloOhms)
HI : Heat Insulation
A : Antistatic shoe (electrical resistance between 0.1 – 1000 MegaOhm)
CI : Cold Insulation
HRO : Heat resistant sole (up to 300ºC)
WRU : Water resistant upper (shoe surface)
E : Energy absorption in the heel
ESD : Electrostatic Discharge
EN ISO 20345 Safety Shoes (200 joules – Steel Impact Resistance)
SB : Basic Safety

02 : Antistatic, Shock Absorbing Heel, Water Resistant
03 : Antistatic, Shock Absorbing Heel, Water Resistant, Steel Midsole

When choosing the sole of the occupational safety shoe, the necessary information about the working environment must be obtained. For example, neotril or nitrile sole should be chosen in working environments with high temperature, acid and alkali. Occupational safety shoes with double density polyurethane soles should be preferred for slip resistance, shock absorption and comfort. Fungal infection is the most common problem related to the use of occupational shoes. However, it should be kept in mind that this problem mostly stems from the lack of knowledge regarding hygiene rules and/or non-compliance with them. In addition, one of the most important reasons why employees avoid wearing occupational shoes is their weight. For this reason, when choosing occupational shoes, care should be taken that the shoes are not heavy (maximum 1 kg/pair).
