Shanghai Market Safety Shoes Need To Be Improved

In the 3 quarter of this year, the Shanghai quality and Technical Supervision Bureau conducted supervision and spot checks on two types of safety shoes, namely, toe safety shoes and electric insulation shoes, which are produced and sold in the city.

This sampling inspection is based on the national mandatory standard GB12011-2000 "electrical insulation shoes general technical conditions" and the industry compulsory standard LD50-1994 "toe toe safety shoes (boots)". For the two types of safety shoes, besides testing the wearability of the outsole, the wearability and the peel strength of the sole, the safety performance indexes of the front end of the shoes, the pressure resistance of the front ends of the shoes, and the electrical properties of the electric shoes are also tested.

After inspection, 27 samples of 40 safety shoes were selected, and the qualified rate was 67.5%.

Among them, there are 23 kinds of products in Shanghai, 17 of them are qualified, the sampling pass rate is 73.9%, the products of other provinces and cities are 17, and 10 kinds are qualified, the qualified rate of sampling is 58.8%.

The main problems found in this spot check are the impact resistance of the front end of the shoe, the anti pressure performance of the front end of the shoe, the poor folding resistance of the outsole, and the unclear identification of the product.

The pressure resistance performance of the front end of the shoe and the disqualification of the front impact resistance of the shoe are mainly shown as the raw material of steel Baotou with low quality and low price, so that the strength and stiffness of the product can not reach the requirements and can not bear the prescribed pressure and impact force.

The failure of the outsole of a shoe sole is a crack that exceeds the specified length after the bending of the shoe sole material after a specified number of times.

This unqualified protection toe safety shoes may be cracked or even broken due to the material of the sole during the wearing process, resulting in the loss of the protective performance of the shoes and the protection of the wearer's toes from being hurt by extrusion.

The main problems found in this spot check are the wear resistance of the outsole, the poor peel strength of the shoes, and the unclear identification of the products.

Some of them are wear-resisting properties of shoe sole materials. Some of them are unevenly distributed after mixing materials, resulting in the same pair of shoes and even the same bottom wear resistance.

The failure of the performance will cause the soles to wear out quickly or wear out, resulting in the loss of the insulation performance of shoes and the protection of wearers from electric shock.

This unqualified performance will cause the soles and shoe upper to be easily disconnected, which also results in the loss of the insulation performance of shoes and the protection of wearers from electric shock.

Product identification is very important for safety shoes and other special labor protection articles.

Because different safety shoes products play a very different protective role.

Product identification plays a direct role in guiding enterprises and operators to select products correctly.

For example, electrical insulation shoes must have "lightning" signs and withstand voltage values, and toe toe safety shoes can be classified into An1~An5 grade five according to impact resistance and compression resistance.

Unclear or incomplete product identification of safety shoes will lead to misuse of labor protection articles by workers, and easily lead to injury accidents.

In addition, the quality and Technical Supervision Department of Shanghai will further intensify the exposure of quality products and poor quality products in the spot checks, and guide enterprises to purchase qualified products for employees so as to ensure the safety and health of workers. At the same time, it will further strengthen the publicity of relevant national mandatory standards for labor protection articles, and enhance the quality awareness and internal product quality control of labor protection articles by combining with the departments in charge of Shanghai Labor Safety Supervision Bureau and other industries, so as to ensure that the production and marketing enterprises and purchasing units of labor protection products can be familiar with standards, so as to promote the overall quality level of the labor protection products industry.
