What To Know About Security Class S1 And S1P?

And then, we come to the more widespread classes: S1 and S1P. Often, shoes in these classes are seen as the first “real” safety shoes. The basic structure of these shoes is usually that of the higher classes. As always, the heart of the shoes is the toe cap, which protects against bumps and falling objects. These can either be made of steel, aluminum, plastic, or, in sporadic cases, titanium.

The exact differences between these materials can be found in our article on cap types. Furthermore, all safety shoes from class S1 must have a closed heel. This eliminates the risk of objects getting into the shoe from behind and causing injuries. In addition, the sole must be treated antistatic to offer the wearer a certain amount of insulation protection. Search for soft sole safety shoes (รองเท้า safety พื้น นุ่ม which is the term in Thai)

However, this should not be confused with ESD certification. There must be a certain amount of energy in the heel area. This ensures that the back and joints are not stressed too much by using the shoes. Last but not least, the outsole must be made resistant to hydrocarbons. In other words, it must not dissolve or deform when it comes into contact with oil or gasoline.

Class S1P also has penetration protection in the sole. This prevents that nails and other pointed objects from pierce through the sole and injure your foot. In this context, the “P” is the abbreviation for “penetration.” The penetration protection consists either of a steel insert under the insole or a solid textile layer under the insole. The advantage of steel inlays compared to their counterparts made of textile is that they offer slightly higher penetration protection but are not very flexible due to the material used.

In addition, with steel insoles, there is a small gap on the sole side through which nails can penetrate. The textile soles eliminate this risk as they are sewn directly to the insole, so there is no gap. In addition, they are significantly lighter and more flexible than those made of steel. In this context, the “P” is the abbreviation for “penetration.”
