Standards and precautions for the implementation of different types of safety shoes in China

China's safety shoes standards have been formulated since the 1990s. In 2007, new standards were formulated to protect the occupational health and safety of workers.

Safety shoes can be roughly divided into: protective toe safety shoes (ie, anti-smashing safety shoes, anti-smash safety shoes), anti-piercing safety shoes (we usually say puncture-proof safety shoes), electric insulation shoes (commonly known as insulated shoes), Anti-static safety shoes, acid and alkali resistant safety shoes.

The standard for protecting toe safety shoes: GB21148-2007/GB21147-2007/GB21146-2007, the highest safety factor is GB21148-2007 is also recommended for the meter shield footwear industry. The safety performance of the inner head is divided into three levels: safety, protection and occupation. The most commonly used ones are safety and protection. Therefore, they are often used in metallurgy, mining, forestry, port, loading and unloading, quarrying, machinery, construction, and petroleum. , chemical industry, etc.

The standard for anti-piercing safety shoes is GB21148-2007, which requires that the anti-piercing strength should be greater than or equal to 1100N in order to be qualified products, suitable for mining, fire protection, construction, forestry, cold work, machinery and so on.

The standard of electric insulation shoes GB12011-2009 is mainly used for electricians, electronic operators, cable installers, substation installers, etc. This kind of shoes can only be worn in the working environment of voltage 6KV and below, and the upper must be kept dry, can not touch the sharps, high temperature and any corrosive substances. If the bottom is corroded or damaged, it cannot be used. Replace the new electrically insulated shoes immediately.

Anti-static safety shoes standard: GB21148-2007, anti-static shoes in some electronics factories, chemical plants, gas stations, liquefied gas filling and other industries wear more, because these industries are flammable places. Wearing anti-static shoes can eliminate the static accumulation of the human body, and the insulation resistance is kept between 100KΩ-1000MΩ, but you can not wear insulated wool thick socks or insulated insoles when wearing this shoes, and should be equipped with anti-static clothing; The resistance value of the shoe is tested within an hour. Only the resistor can be used as an anti-static shoe within the specified range. Otherwise, it cannot be worn as an insulated shoe.safety shoes

The standard for the implementation of acid and alkali resistant shoes is GB12018-1989. The shoes are used in the fields of electroplating, pickling, electrolysis, dosing, chemical manipulation, etc., but the concentration of acid and alkali should not be too high in these fields; the shoes can not be exposed to high temperatures. Can not be injured by sharps, the soles can not leak, should be washed immediately with water after drying, can not be directly irradiated or dried in the sun.
