4: Acid and alkali resistant safety shoes: suitable for the chemical industry. Note that acid and alkali resistant shoes are not suitable for PU soles.

Parameter standards:


According to the GB21148-2007 safety shoe testing standard, the pressure resistance reaches 15KN and the impact resistance reaches 200J.


In addition, anti-static safety shoes also require a resistance value between 100K ohms and 1000M ohms.


 


Protection level:


There are five main levels of protection for safety shoes:


1. An1 has the best protection level and is mainly suitable for wearing in workplaces such as metallurgy, mining, ports, ships, loading and unloading, quarrying, and heavy industry.


2. An2 has a good level of protection and meets the usual functions of anti smashing and anti-collision. Suitable for use in workplaces such as machinery, construction, and petrochemicals.


3. An3 protection level safety shoes are mainly suitable for use in fields such as electronics, food, and hospitals.


4. An4 protection level safety shoes are suitable for work scenarios such as the textile industry.


5. An5 protection level is second, and it is also suitable for work scenarios with relatively small injuries such as the textile industry.
Baotou material:


During the wearing process of safety shoes, the toe cap of the shoe provides effective protection for the feet, avoiding injury to the toes or heavy objects pressing on the feet. Baotou generally uses materials such as steel heads, fiberglass, and plastic steel, with steel heads being the majority.






For the dust-free industry, anti-static safety shoes are generally used, and the picture is equipped with three types of safety shoes: long tube safety shoes, short tube safety shoes, and no tube safety shoes
