How to choose electric performance protective shoes? What are the electrical performance protective shoe signs?

First, the choice of electrical performance protective shoes

1. According to the national standard, the selection of electrical performance protective shoes shall be in accordance with the national standard GB11651-1989 "Selection rules of labor protection articles" and "Standard for the Provision of Labor Protection Articles (Trial)" issued by the State Economic and Trade Commission on March 6, 2000. Or local, industry related regulations can also be selected according to the type of protection injury and the working environment, such as work environment, the main risk factors for electrostatic damage, and the work surface is conductive ground, consider using conductive shoes; may be at the same time Workplaces with a low voltage (below 250V) shock hazard, and the work surface is anti-static ground, may consider using anti-static shoes. Anti-static shoes and conductive shoes are mainly used in petrochemical, pharmaceutical and electronics industries. If the main risk factor in the work environment is electric shock, electrified shoes should be used when electrified.

2, according to the environment choice: Users can choose different materials of electrical performance protective shoes according to the work environment. In most of the electronics industry and pharmaceutical industry, the environment is cleaner and the work intensity is relatively low (walking less). Cloth-resistant anti-static shoes or conductive shoes can be used. They are light, comfortable, and have good air permeability; they are 1kV at power frequency. The following live working places, and the environment is relatively dry, can use electric insulation shoes or electrical insulation cloth shoes with voltage resistance of 15kV or less; at workplaces with power frequency voltage of 1kV or more, or the environment is more humid, the withstand voltage of 15kV or more can be selected. Electrically insulating rubber boots or electrically insulating plastic boots; In the petrochemical industry, including refueling (gas) stations, the working environment is relatively complex, and the work intensity is relatively high (moving more). Anti-static shoes or conductive shoes may be used, and it is more resistant to dirt. wear. In use, the provisions of the electrical safety working procedures (DL408 and DL409) must also be strictly observed.

3, according to preferences: leather footwear electrical performance protection shoes can also be based on the user's preferences, use different production processes and the appearance of quality products. At present, the more common is the glue and injection type shoes, line seam leather shoes for the majority of car tires and anti-wool insulation shoes, molded shoes are now rarely used. Appearance quality is generally easier to judge, such as whether the helper has disability, color is not the same, and the line re-needle, jump needle, broken line, pin code is uneven, whether the bottom of the opening to open the plastic, off the line, soles and plastic surface is Sulfur, sulfur, sulfur, etc. The intrinsic quality requires inspection of the factory inspection certificate of the product. It is advisable to check the inspection report issued by a third-party inspection agency approved by the national government as the basis for judging the quality of the product.

Second, the sign of electrical performance protective shoes

Anti-static shoes, conductive shoes and electrical insulating shoes are all special labor protection products. The state implements a safety sign management and production license system for special labor protection articles. The production enterprises of such products must obtain the “Safety Sign Certificate” and the “Production Permit for Industrial Products” issued by the National Special Labor Protection Products Safety Signs Management Center before they can produce and sell the products within the validity period of the certificate. When purchasing the above products, the enterprise shall require the distributor to present the inspection report of the batch of products, as well as a copy of the manufacturer's safety mark certificate and production license, and file it for archiving.

Manufacturers must also have on their products and packaging printed with signs that meet the requirements of the standard, along with product specifications and certificates, as well as safety signs and QS signs. Shoe type shoe number, trademark, use instructions, manufacturing date and production lot number. Electrically insulating footwear (boots) products should have the following signs: Standard number, electrical insulation (or EH), lightning marking, and voltage resistance values ​​should be provided on the upper or sole of each pair of shoes; manufacturer's name, shoe size, Product or brand name, date of production, and inspection certificate of electrical insulating properties There should be a standard number, a manufacturer's name, and a product name on the small package of the product (example: 6kV cow leather surface insulated leather shoes), shoe number, trademark, and instructions for use.
