Introduction / Labor Insurance Shoes

Special protective shoes should be inspected and kept clean after use and stored in a non-polluting and dry place.
Classification / Labor Insurance Shoes
Labor insurance shoes are generally divided into:
Anti-smashing protective shoes, anti-smashing puncture protective shoes and electric insulation protective shoes (withstand voltage > 6 kV) three. The anti-smashing shoes and the steel-toed steel shoes are the same type, that is, the safety shoes that protect the toes, the main function is to prevent falling objects from hurting the feet.
Anti-piercing protective shoes are used for foot protection to prevent stab wounds from various sharp objects.
Others depending on the occasion of use and the special use of protective shoes, there are also points:
Oil-proof protective shoes are used in places where oil or oil splashes;
Waterproof protective shoes are used in workplaces where water or splashing water is used;
Cold-proof protective shoes are used for foot protection of low-temperature workers to protect against frostbite.
The main function of steel-making labor insurance shoes is to prevent burning and puncturing. It should be able to withstand a certain static pressure and withstand certain temperatures and is not flammable. These types of labor insurance shoes are suitable for smelting, furnace, cast iron and so on.
In addition to the above, there are some special labor insurance shoe covers, such as canvas, asbestos, and aluminum-covered labor insurance shoe covers. The most important thing to choose for labor insurance shoes depends on whether the manufacturer has obtained the "National Industrial Product Production License" and "LA Safety Mark Certification". Is there a test report on the relevant standards, whether the test method is correct, and whether the result is true.
Method of measuring labor insurance shoes / labor insurance shoes
Labor insurance shoes are more suitable for winter wear. Workers are used frequently. 1. Shoe type: (abbreviation: model), that is, the length and width of the shoe. Is the width and tightness of the shoe body correct with the foot? 2, upper: whether the softness of leather can be natural and suitable when walking. 3, shoes state: the entire shoe state can stick to the foot without hitting the feet, loose and not off, flexible. 4, inner pad: whether the correct use of vibration-activating function, sweat-absorbing function, massage function, health care function structure. 5, lining: Is there a correct choice of ventilation, waterproof, warmth, environmentally friendly functional materials. 6. Sole: It is suitable for regional and various environments to use different levels of substrate and anti-skid requirements. For example: good environment with relatively non-slip, lightweight substrate, and outstanding vibration-proof function. The outdoor site environment is reinforced with anti-slip, wear-resistant substrate and can withstand harsh environments. Subdivided into: white-collar, blue-collar, wages, administrative industry, light industry, heavy industry, construction site, tourism, service industry, etc.
Main performance / labor insurance shoes
Baotou impact resistance
The impact test shall be carried out with a steel impact hammer of a specified weight. The height of the gap under the toe cap shall be less than the specified value when the toe cap is impacted, and the piercing shall not show any penetrating cracks in the direction of the test axis. It is worth noting that the national standards have different regulations on the weight, specifications, impact height and construction of the test machine. The actual test should be distinguished.
Puncture resistance
The test machine is equipped with a pressure plate on which the test nail is mounted. The test nail is a tip with a cut-off tip, and the hardness of the nail head should be greater than 60HRC. The sole sample is placed on the chassis of the testing machine in such a position that the test nail can be pierced through the outsole, and the test nail pierces the sole at a speed of 10 mm/min ± 3 mm/min until the penetration is completed. The greatest strength. Four points are selected on each sole for testing (at least one of which is at the heel), each point is not less than 30 mm apart, and the distance from the insole edge is greater than 10 mm. The bottom of the anti-slip block should be pierced between the blocks. Two of the four points should be tested within 10-15 mm of the edge line of the bottom of the plant. If humidity affects the results, the sole should be immersed in deionized water at 20 °C ± 2 °C for 16 ± 1 h before testing.
Electrical properties of conductive shoes and anti-static shoes
After the shoe sample is adjusted in a dry and wet atmosphere, the clean steel ball is filled into the human shoe and placed on the metal probe device, and the first two probes and the third probe are measured using a prescribed resistance tester. Resistance between. Under normal circumstances, conductive shoes require resistance should not be greater than l00K ohms; anti-static shoes require resistance should be between 100K ohms and 100M ohms.
Use specification/labor shoes
Oil-proof protective shoes are used in areas where oil or splashing oil is used; waterproof protective shoes are used in workplaces where water or splashing water is used; cold-proof protective shoes are used for foot protection of low-temperature workers to protect against frostbite.
Anti-piercing protective shoes are used for foot protection to prevent stab wounds from various sharp objects.
The main function of the anti-smashing shoes is to prevent the falling objects from hurting the feet. The front head of the labor insurance shoes has impact resistant materials.
The main function of steel-making labor insurance shoes is to prevent burning and puncturing. It should be able to withstand a certain static pressure and withstand certain temperatures and is not flammable. These types of labor insurance shoes are suitable for smelting, furnace, cast iron and so on.
In addition to the above, there are some special labor insurance shoe covers, such as canvas, asbestos, and aluminum-covered labor insurance shoe covers.
Selection and maintenance of protective labor insurance shoes The selection of protective shoes should be based on the nature of the work environment and the degree of hazard. Protective protective shoes should have a product certificate and product specifications. Read the instructions before use, and use the method correctly.

The focus of this special action inspection is: a key industry: construction sites, automobile repair and distribution, labor protection products use and sales units. Second key protective equipment: safety helmet, safety belt, safety net, dust mask, gas mask, anti-impact eye protection, special overalls (anti-static, acid-proof, flame retardant), safety shoes (anti-static, insulation, anti-mite , special anti-puncture, acid and alkali protection and other labor protection products. This activity strengthened the supervision and inspection of labor protection articles in the circulation field, prevented counterfeit and shoddy labor protection articles and special labor protection articles without safety signs from entering the market, effectively protecting the legitimate rights and interests of production and operation units and visiting the lives and health of the employees.
