General information on foot protection

The company must provide safety shoes and the employees must wear them if foot injuries are expected to be caused by impacting, jamming, falling or rolling objects, by stepping on pointed or sharp objects or by hot substances, hot or corrosive liquids.

European standardisation according to DIN EN 20344 to 20347
The area of foot protection is regulated in the standards DIN EN 20344 to DIN EN 20347. In these standards, shoes with different protection levels are for the first time recognised differently. The previously used generic term, protective shoes, is thus dispensed with. Depending on whether there is an in-built or absent toecap, a distinction is made between:

1. Basic requirements and test procedures according to DIN EN 20344 for safety, protective and occupational shoes for company use.

2. Safety shoes according to DIN EN 20345 with toe cap for high pressures, the protective effect of which is tested with energy of 200 joules (Abbreviated designation S).

3. Protective shoes according to DIN EN 20346 with toecap for high pressures, the protective effect of which is tested with energy of 100 joules (Abbreviated designation P).

4. Occupational shoes according to DIN EN 20347 without toecap. If a cap is present, there are no requirements for the toecap (Abbreviated designation O). 

The use of the respective shoes is determined by the nature of the hazard. For all shoes, additional requirements may be necessary (e.g. requirements for heat and cold insulation, penetration resistance or electrical resistance). These shoes must then be labelled accordingly. 

Abbreviation for occupational shoes DIN EN ISO 20347 – without toecap

OB
meets the basic requirements

O1
closed heel area • antistatic and energy absorption capacity in the heel area

O1P
as O1, however, additionally with penetration resistant intermediate sole

O2
as O1, however, additionally for areas in which the effect of moisture is to be expected

O3
as O2, however, additionally penetration resistant • profiled outsole

Abbreviation for DIN EN ISO 20345 safety shoes – 200 joules toe cap test energy

SB
meets the basic requirements • can be open in the heel area

S1
with steel cap or plastic cap or aluminium cap – for areas in which the effect of moisture is not to be expected, closed heel area, antistatic and energy absorption capacity in the heel area

S1P
as S1, however, additionally with penetration resistant intermediate sole (only for dry areas)

S2
as S1, however, additionally for areas in which the effect of moisture is to be expected

S3
as S2, where moisture is to be expected and additionally the danger of stepping on pointed or sharp objects, in particular in the construction industry as well as in the pit and quarry industry

S4
Areas with increased effect of liquids, moisture and debris. With steel cap or plastic cap or aluminium cap, profiled outsole, antistatic and energy absorption capacity in the heel area

S5
as S4, however with penetration resistant intermediate sole

Additional requirements for special uses with corresponding symbols for safety shoe labelling:

A:          antistatic shoe
E:          Energy absorption in the heel area
WRU:     Shaft, water penetration and water absorption
WR:       water-repelling shoe
P:          Penetration resistance
CI:         Cold insulating
HI:         Heat insulating
HRO:      Heat resistance to contact heat
M:          Metatarsal bone protection
CR:        cut-resistant shaft
FO:        oil and petrol-resistant shoes
SRA:       Friction coefficient (Slip prevention) Ceramic tile / glycerine
SRB:       Friction coefficient (Slip prevention) Steel floor / cleaning agents
SRC:       Friction coefficient (Slip prevention) Ceramic tile / glycerine and steel floor / cleaning agents

EN ISO 20349
This standard for shoes to protect against thermal risks and splashes from molten metal supplements EN ISO 20345 for safety shoes through minimum requirements which occur in foundries as well as with welding work and related processes. For foundry boots, resistance to the effect of molten metal is tested in addition to other requirements. Depending on the result, the shoe is labelled with “Al” following a successful liquid aluminium test and/or “Fe” following a successful liquid iron test. All other labels known from EN ISO 20345, besides the above, remain unchanged.
 
ESD SAFETY SHOES
ESD = Electro Static Discharge

Shoes are label as ESD shoes when the electrical resistance according to DIN EN 61340 is between 7.5 x 105 Ohm to 3.5 x 107 Ohm or 0.75 MOhm to 35 MOhm. ESD shoes should be used when an electrostatic discharge must be avoided by conducting away the charges. Contamination, moisture and the temperature can considerably change the electrical resistance.

The user is thus recommended to carry out a regular on-site test of the electrical resistance.

Warning: ESD shoes are not suitable for electricians or for work on sources carrying electrical voltage.
