Standard specification for safety shoes

The standard specifications of safety shoes are usually formulated by the national or industry relevant agencies to ensure that safety shoes meet certain requirements in protecting the safety of workers' feet. The following are some of the main contents and key points of China's safety shoe standards:

First, national standards

China's current national standard for safety shoes is "Foot protection - Safety shoes" (GB 21148-2020), which will be implemented on August 1, 2021, and is under the supervision of the Ministry of Emergency Management, PRC. It replaces several previous standards (GB 12011-2009, GB 21146-2007, GB 21147-2007 and GB 21148-2007). This standard specifies the terms and definitions of safety shoes, classification, style and marking, basic requirements, protective performance, additional requirements, marking and information to be provided by the manufacturer.

Second, the main content and requirements

Terms and definitions: Defines terms related to safety shoes, leather, polymeric materials, protective caps, etc.

Classification and marking: According to the different protective performance, safety shoes are divided into different categories, and are distinguished by specific marking symbols.

Basic requirements: including material requirements (such as the material and performance of the upper and sole), structural design requirements (such as the combination strength of the upper and sole, the installation and fixing of the steel head, etc.) and ergonomic requirements (such as the weight of the shoe, air permeability, comfort, etc.).

Protection performance:

Anti-smashing performance: the shoe head is equipped with an anti-smashing head made of steel or composite materials, which can withstand a certain impact force (such as static pressure protection of more than 15KN and energy impact pressure protection of 200J).

Puncture resistance: The midsole is made of special materials to prevent sharp objects from penetrating through the sole (such as puncture resistance ≥1100N).

Anti-slip performance: The sole is made of wear-resistant, anti-slip rubber material, and is designed with special anti-slip lines. Although China currently does not have a special national standard for anti-slip performance, safety shoe soles usually exceed the industry standard anti-slip rating.

Insulation performance: For workers who need to contact live equipment, safety shoes should have good insulation performance (such as leakage current ≤1.8mA when the experimental voltage is 6KV).

Other special properties: such as high temperature resistance, water resistance, cold resistance, oil resistance, acid and alkali resistance, according to the different working environment varies.

Additional requirements: including anti-slip requirements, wear resistance requirements for the lining of the shoe seat area, and general requirements for toe protection.

Information should be provided by the manufacturer: The safety shoes should be marked with the manufacturer, production date, shelf life, protection level and other information, so that users can understand and choose.

Third, implementation and supervision

The production and sale of safety shoes shall strictly comply with the requirements of national standards and relevant laws and regulations. The relevant regulatory authorities will regularly conduct random inspections and inspections of safety shoes on the market to ensure that their quality and protective performance meet the standard requirements. At the same time, enterprises should also strengthen internal management and quality control to ensure that the safety shoes produced meet national standards and user needs.

Fourth, Conclusion

The standard specification of safety shoes is one of the important measures to ensure the safety of workers' feet. Through the development and implementation of strict standards and specifications, it can be ensured that safety shoes meet certain requirements in terms of material, structure, performance, etc., so as to effectively prevent the occurrence of various foot injuries. Therefore, when selecting and using safety shoes, relevant standards and requirements should be strictly observed to ensure the safety of workers' feet.
