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

First, the selection of electrical performance protective shoes

1. When choosing electrical performance protective shoes, it is essential to follow national standards such as GB11651-1989 “Rules for Selecting Labor Protection Articles” and the “Standard for the Provision of Labor Protection Articles (Trial)” issued by the State Economic and Trade Commission on March 6, 2000. Additionally, local or industry-specific regulations can also be considered based on the type of hazard and working environment. For instance, in environments where static electricity poses a risk and the floor is conductive, conductive shoes are recommended. If the workplace involves low-voltage hazards (below 250V) and the floor is anti-static, anti-static shoes may be appropriate. These types of shoes are commonly used in industries like petrochemicals, pharmaceuticals, and electronics. In cases where electric shock is the main risk, insulated shoes should be worn.

2. Environmental factors also play a key role in selecting the right footwear. In clean environments with low work intensity, such as in electronics or pharmaceutical industries, cloth-resistant anti-static or conductive shoes are suitable due to their comfort and breathability. For live working areas at 1kV power frequency, or dry environments, insulating shoes rated up to 15kV are ideal. In high-voltage settings (1kV or more) or humid conditions, shoes with higher voltage resistance (15kV or above) should be used, such as rubber or plastic insulating boots. In complex environments like gas stations or petrochemical facilities, where movement is frequent and dirt resistance is important, anti-static or conductive shoes are preferred. Always follow the guidelines outlined in DL408 and DL409 for safe electrical work practices.

3. Personal preference also influences the choice of protective shoes. Leather-based electrical protective shoes come in various styles and production methods, with glue and injection types being most common today. Traditional stitched leather shoes are still widely used, while molded shoes are less popular. When evaluating quality, check for visible defects like uneven stitching, broken threads, or misaligned soles. The intrinsic quality should be verified through factory inspection certificates and third-party reports from government-approved agencies. This ensures that the product meets safety and performance standards.

Second, the marking of electrical performance protective shoes

Anti-static, conductive, and insulating shoes are all classified as special labor protection equipment. The Chinese government enforces a safety mark system and requires manufacturers to obtain a “Safety Sign Certificate” and a “Production Permit for Industrial Products” from the National Special Labor Protection Products Safety Signs Management Center before they can legally produce and sell these items. When purchasing, companies should ask suppliers to provide batch inspection reports, along with copies of the manufacturer’s safety certificate and production license for record-keeping.

Manufacturers must ensure that their products and packaging are clearly labeled with required information, including standard numbers, product specifications, certificates, safety signs, and QS marks. Each pair of insulating footwear should have the standard number, insulation rating (EH), lightning symbol, and voltage resistance values printed on the upper or sole. The manufacturer’s name, shoe size, product name, date of manufacture, and an electrical insulating property certificate should also be included. On the small package, details like the standard number, manufacturer name, product name, shoe size, trademark, and usage instructions must be present. For example, a label might read: “6kV cow leather surface insulated leather shoes.”
