In the GB21147-2007 "Personal Protective Equipment Protective Shoes" and GB21148-2007 "Personal Protective Equipment Safety Shoes" released in 2007, anti-puncture shoes, anti-static shoes, conductive shoes, protective toe shoes, etc. are all included in professional shoes ( The scope of unprotected toe caps), safety shoes and protective footwear. The relationship between professional shoes, safety shoes and protective shoes can be expressed as follows:
So how do you choose safety shoes in different industries?
Protective toe safety shoes
Protective toe safety shoes are shoes made of leather or other materials and equipped with a metal or non-metal inner toe at the front end of the shoe. They can withstand a certain amount of force and protect the toes from external objects. According to the definition of GB|T12903-2008 "Individual Labor Protection Equipment Terminology", the front end can withstand 200J energy impact and 15kN pressure to protect the toe safety shoes, while the impact of 100J energy and 10kN pressure called protection toe Protective shoes.
Suitable for loading, unloading, mining, petroleum, quarrying, metallurgy, port, machinery, construction, forestry, chemical and other industries.
Anti-piercing safety shoes
The puncture-proof shoes are placed between the insole and the outsole of the shoe to prevent the sharpness of the object from puncture and protect the bottom of the foot from injury. Its products should comply with the provisions of GB21148-2007 "Safety Shoes".
Suitable for mining, fire protection, construction, forestry and other industries.
Electrically insulated safety shoes
Insulated shoes are a kind of safety shoes made of insulating materials. The applicable range of electric insulation shoes, the new standard clearly points out: electric insulation shoes and cloth surface insulation shoes with the test voltage less than 15KV, applied in the working environment of power frequency (50-60F) below 1000V, test electric power above 15KV The city's electric insulation rubber shoes are suitable for working environment above 1000V.
Suitable for electricians, electronic operators, cable installers, substation installers, etc. The 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
Anti-static shoes are protective shoes that can eliminate static electricity accumulation in the human body and prevent electric shock from power supply below 250V.
Suitable for flammable workplaces, such as gas station operators, liquefied gas filling workers, etc.
Note: It is forbidden to use as insulated shoes. Wear anti-static shoes should not wear insulated wool stockings or use insulated insoles. Anti-static shoes should be used together with anti-static clothing. Anti-static shoes should generally be tested for shoe resistance once less than 200 hours. If the resistance is not within the specified range, it cannot be used as an anti-static shoe.
Choose the safety shoes to follow the following 5 points:
A. In addition to the appropriate type of protective footwear, it is also important to fit the foot and make it comfortable to wear. It is very important to carefully select the appropriate shoe size.
B. Protective shoes should have a non-slip design, not only to protect people's feet from injury, but also to prevent accidents caused by the operator being slipped.
C. Various protective shoes with different performances must meet the technical indicators of their respective protective performance, such as the toes are not bruised, the soles of the feet are not stabbed, and the insulation is required.
D. Before using protective shoes, carefully inspect or test. In electrical and acid-based operations, damaged and cracked protective shoes are dangerous.
E. Protective shoes should be properly kept after use. Rubber shoes should be rinsed with water or disinfectant and dried to extend the service life.
Correct use and maintenance methods:
1. The construction of safety shoes must not be modified without authorization.
2. Wear safety shoes of the appropriate size to help maintain the wearer's foot health and the durability of the footwear.
3. Pay attention to personal hygiene. Users should keep their feet and shoes clean and dry.
4. Clean the safety shoes regularly, but do not use solvents as detergents. In addition, the sole must be cleaned frequently to avoid accumulation of dirt, because the conductivity or anti-static performance of the sole is affected by the amount of adhering dirt and the flexing.
5. Store safety shoes in a cool, dry and well ventilated area.
