Safety shoes are essential for providing safety protection for the feet in various working environments. There are several types of safety shoes, each designed to meet specific needs.

One type is the toe – protecting and puncture – preventing safety shoes. These shoes are not only effective in preventing punctures but also have anti – impact and super anti – slip functions. They can protect the feet from being stabbed by sharp objects on the ground and also from the impact of falling objects. The main function of anti – impact safety shoes, a related type, is to prevent falling objects from injuring the feet. Their toe caps are made of impact – resistant materials.

Another important function of safety shoes is insulation. Some safety shoes are designed to provide insulation, which is crucial in environments where there is a risk of electrical shock. There are also safety shoes that are resistant to acids and alkalis, protecting the feet from chemical damage.

When it comes to the selection of safety shoes, it should be based on the nature and degree of hazards in the working environment. For example, if the work involves a lot of walking on slippery surfaces, safety shoes with anti – slip design are necessary. These shoes not only protect people’s feet from injury but also prevent accidents caused by operators slipping.

In addition, safety shoes should meet certain standards. In the national standard GB21148 – 2007 “Industrial safety shoes”, the anti – puncture standard for safety shoes is stipulated. They should be able to withstand a puncture force of 1100N, meaning they can withstand the puncture of a steel needle with a diameter of 4mm without being penetrated.

Before using safety shoes, it is important to read the instruction manual that comes with the product certificate according to the usage conditions and use them correctly. For special protective safety shoes, after use, they should be checked and kept clean, and stored in a pollution – free and dry place to ensure their long – term effectiveness.
