China's safety footwear standards
Safety shoes are a general term for safety shoes and protective footwear. They are generally used to protect the feet and legs from foreseeable injuries in different workplaces.
In fact, China's relevant national departments attach great importance to the occupational health and safety of workers. In the 1990s, strict safety shoe production and inspection standards LD50-94 were designated. In 2007, the European CEENISO20345:2004/2007 standard was adopted, and national personal protective equipment standardization was adopted. The Technical Committee (CSBTS/TC 112) has developed a new standard for safety shoes: personal protective equipment safety shoes GB21148-2007/personal protective equipment protective shoes GB21147-2007/personal protective equipment professional shoes GB21146-2007. Domestic safety shoes can be roughly classified as Protective toe safety shoes (ie, anti-smashing shoes, anti-smash safety shoes), anti-piercing safety shoes (also commonly known as puncture-proof safety shoes), electrically insulated shoes (that is, we usually call insulated shoes), anti-static Safety shoes, acid and alkali resistant. The protective shoes generally only have the protection head at the front of the shoes and the safety shoes. The rest of the functions can be the same. The protection head of the protective shoes is protective, and the safety protection head is safe. Of course, the protection effect is safe. Better, the fish and the bear's paw are not compatible, and the weight of the safety shoe is heavier than that of the protective shoe (because the weight of the safety protection toe cap is generally greater than the weight of the protective protective bag). Professional shoes are shoes that do not contain protective toe caps, and other safety shoes have functional professional shoes.
Anbang Safety Shoes introduces you to the following types of safety shoes:
·Protection toe safety shoes: According to GB21148-2007/GB21147-2007/GB21146-2007 standards, the safety performance of inner head is divided into three categories: safety, protection and occupation. Safety type is the most suitable for metallurgy, mining, Forestry, port, loading and unloading, quarrying, machinery, construction, petroleum, chemical industry, etc. Commonly used for safety and protection, the Oriental sneaker safety shoes all adopt safety tamper-proof standards.
·Puncture-proof safety shoes: It is carried out according to GB21148-2007 standard. The anti-piercing strength is greater than or equal to 1100N. It is suitable for mining, fire prevention, construction, forestry, cold work, machinery and so on.
·Electrically insulated shoes: It is implemented according to GB12011-2009 standard, and is suitable for electricians, electronic operators, cable installers, substation installers, etc. Note: Suitable for working environment with power frequency below 1KV, working environment should keep the upper dry. Avoid contact with sharp objects, high temperature and corrosive substances, and the bottom must not be corroded and damaged.
·Anti-static safety shoes: According to the GB21148-2007 standard, it can eliminate the static electricity accumulation of the human body. Its insulation resistance requirement is greater than or equal to 100KΩ and less than or equal to 1000MΩ. It is suitable for flammable workplaces, such as chemical plants, gas station operators, liquefied gas irrigation. Loading work, etc. Note: It is forbidden to use as insulated shoes; wear anti-static shoes should not wear insulated wool thick socks or use insulated insoles at the same time; anti-static shoes should be used together with anti-static clothing; anti-static shoes should not be used for more than 200 hours. The shoe resistance value is tested once. If the resistance is not within the specified range, it cannot be used as an anti-static shoe.
· Conductive shoes: According to GB21148-2007 standard, conductive shoes have good electrical conductivity, can eliminate the static accumulation of human body in a short time, can only be used for protective shoes without electric shock hazard, the insulation resistance requirement is less than 100KΩ. Conductive shoes are mainly used in places that require high degree of anti-static or particularly flammable and explosive, such as detonators, explosives, etc. Note: It is absolutely forbidden to use as insulated shoes; wear conductive shoes should not wear insulated wool thick socks or use insulated insole at the same time; conductive shoes should be used with conductive clothing at the same time; conductive shoes should generally be used for shoe resistance not exceeding 200 hours. Once tested, if the resistance is not within the specified range, it cannot be used as a conductive shoe.
· Acid and alkali resistant safety shoes: It is implemented according to GB12018-1989 standard, and is suitable for electroplating workers, pickling workers, electrolysis workers, liquid distributors, chemical operators, etc. Note: Acid and alkali resistant shoes can only be used in acid and alkali working places with low concentration; avoid contact with high temperature, sharp damage to the upper or sole leakage; apply water to wash the acid and alkali liquid on the shoes after wearing, then Allow to dry and avoid direct sunlight or drying.
Safety protective shoes are high-tech and high value-added footwear products. The production process of safety protective shoes has high requirements on raw materials, auxiliary materials, chemical materials, mechanical equipment, etc. At present, many domestic footwear with certain scale and grades Enterprises have turned their attention to safety protection shoes, a market segment that has been occupied by developed countries.
