Requirements for the use and management of MA and KA certification marks by enterprises 2021-09-22 11:36 · Zhongnuo Testing specializes in explosion-proof certification. The safety mark management system for mining products is a mandatory regulatory framework applied to products related to safe mining operations as well as the safety and health of miners (including equipment, materials, safety instruments, etc.). For mining products subject to safety mark management, the manufacturing units must obtain the corresponding safety marks before they can produce and sell such products, and mines can only purchase and use them after that. Safety markings are symbols and certificates that confirm that mining products meet relevant **standards, industry standards, and mine safety regulations**, allowing production units to manufacture and sell them, as well as enabling user units to purchase and use them. They also serve as an important tool and basis for relevant **authorities and work safety supervision agencies** to carry out supervision and inspection of equipment safety in accordance with the law. A safety mark consists of a safety mark identifier and a safety mark certificate. The basic graphic symbol for the safety mark of products used in coal mines is MA; the basic graphic symbol for the safety mark of products used in metal and non-metal mines is KA. Mining products that have obtained safety marks must be equipped with safety mark labels in a prominent position on their exterior. The safety mark certificate contains basic information such as the holder, the manufacturing unit, the product specifications and model, the applicable standards, the safety mark number, and the valid period of the safety mark. https://p6-tt.byteimg.com/origin/pgc-image/36c99bd9fd2845e9b8c027385fa4c3c7?from=pc Security tokens can only be used within their valid period. If it is necessary to extend the validity period, an extension application must be submitted; upon completion of the required proper procedures, the safety mark may be used for an extended period. After 30 years of continuous development and improvement, the management of safety signs has been integrated into both the hierarchical control of safety risks and the mechanism for identifying and addressing potential hazards in coal mines, as well as into the system for supervising and inspecting coal mine safety. It has become a fundamental system for ensuring safe coal mining operations in China, and an important tool for managing safety at the source and during the production process. It plays an irreplaceable role in preventing major disasters in coal mines, improving the level of safety in these industries, and contributing to a sustained and stable improvement in the situation regarding safe coal mining.
