Safety Requirements

Potential Hazards

Choosing the right shoe for the specific demands of the job is essential to ensuring that a safety shoe provides proper protection. Safety shoe must be chosen judiciously based on nature of industry and potential hazards.

  • Our body continuously accumulates electrostatic charges while performing everyday activities.
  • This accumulation of charges on the human body is often lethal to static sensitive electronic components and can lead to electrical hazards or cause ignition of chemicals/explosives.
  • It is very important to discharge undesired electrostatic charge in certain industries where employees come into contact with processes, materials or objects which are sensitive to electrostatic charge.
  • In these industries it is necessary to use safety shoes that conduct electrostatic charge and thereby maintain the body at zero charge.

The choice of a particular shoe depends on the type of occupational risk. As with all the footwear, additional requirements may exist (e.g. in terms of heat and cold insulation, penetration resistance or electrical resistance via ESD). These shoes are then mark accordingly.

The testing principles for all basic and additional requirements are specified in DIN EN 344-1/-2 and EN ISO 20344.

Requirement Met -

Requirement can be met but is not stipulated -

* Penetration resistance – Warning - Please note that the penetration resistance of this footwear has been measured in the laboratory using a truncated nail of diameter 4.5 mm and a force of 1100 N. Higher forces or nails of smaller diameter will increase the risk of penetration occurring. In such circumstances alternative preventative measures should be considered.
