AQ 6105-2008 "Foot Protection Miner Safety Boots" safety production industry standards approved by the State Administration of Work Safety, has been implemented since January 1, 2009. The standard is designed to address the hazards of the mining industry environment and is designed to protect miners' legs from risk factors in the work area. As a product standard, it is applicable to the quality evaluation of all-rubber and all-polymer safety boots worn in mining enterprises, and will be enforced by industry standards and become the basis for the production, supervision, management and use of miners' safety boots.
Standard setting background
With the development of the economy, the demand for safety protection products will also increase, and will eventually be reflected in the standard revision of personal protective equipment, and regulate the production safety of enterprises from the height of laws and regulations.
In the accidental injury of miners, accidents in which the feet were bruised and stabbed occurred, causing the miners to fail to work properly and even causing permanent disability. At the same time, the operating environment of mining enterprises is complex, and the damage is diverse. The protective shoes worn by miners in the work need to have various protective functions, such as anti-smashing, anti-piercing, anti-static and so on. Therefore, it is especially important to ensure the performance requirements of the miners' safety boots, so as to effectively prevent the occurrence of miners' foot injury accidents and improve production efficiency.
AQ 6105-2008 "Foot Protection Miner Safety Boots" standard is one of the 2007 safety production industry standard plan projects of the State Administration of Safety Supervision. At the beginning of the project implementation, the existing domestic labor insurance footwear standards generally have a single protective performance requirement, technical requirements are backward and incomplete, and the testing methods are inconsistent with international standards, especially in terms of physical and mechanical properties of the shoes, and the international advanced level. The gap is large. As far as safety shoes are concerned, they are usually referred to as An1 type protective toe safety shoes in China. The implementation standards are LD 50-1994 and HG 3081-1999. The safety performance of these two standards is only the anti-smashing requirement, and the standard technical content. behind. Another domestic industry standard - HG 2402-1992 "industrial mining boots", but it is only applicable to general labor protection boots for industrial and mining enterprises made of rubber, no other protection requirements such as anti-mite, anti-piercing, anti-static, etc. . With the continuous development of industrial production, new materials and new technologies are constantly emerging, and there is an urgent need to have standards that are compatible with them.
In view of this, according to the actual production and operation of domestic labor insurance shoe manufacturers and the protection needs of mining enterprise workers, domestic experts put forward the "Mineral Safety Boots" safety production industry standard formulation project, and approved by the State Administration of Safety Supervision, and invited the country. Safety production Xuzhou Labor Protection Products Testing and Inspection Center participated. The standard technical content refers to the current international and domestic advanced standards, which concentrates the protection performance that is more commonly needed in the production of mining enterprises, and is suitable for the production and use guidance of all rubber and all-polymer safety boots. If it is used for product supervision and certification, it will enhance the operability of the issuance and implementation of licenses and safety signs. On the one hand, it can reduce the burden on production enterprises; on the other hand, it can improve the intrinsic quality of products and provide workers with more Good occupational protection to prevent foot injury accidents.
Description of standard technical content
In some workplaces of mining enterprises, workers are generally only allowed to wear safety boots with all-rubber or full-polymer materials due to production process and technical conditions. Therefore, the standard technical content is mainly based on such foot protection equipment. Request for development.
In terms of design, "Foot Protection Miner Safety Boots" mainly refers to some provisions of ISO 20345: 2004 "Personal Protective Equipment Safety Shoes". In addition to the basic style and size requirements, the standard also specifies reflective tape requirements in the design. This is due to the limitation of the underground working environment, the light is dim, and the accident of hitting the miner occurs. The reflective belt is added on the boot to protect the miners in the operation from being caught in time. In the process of accident rescue, it is also convenient to find trapped miners. Due to the limitations of the test conditions, the standard only specifies the qualitative and dimensional aspects of the reflective tape. When the technical conditions are mature, the quantitative test method will be added in the next revision.
In terms of physical and mechanical properties, the "Foot Protection Miners Safety Boots" mainly refer to ISO 4643: 1992 "Molded plastic shoes - lined or unlined PVC industrial boots" and ISO 2023: 1994 "Rubber shoes - lined industry The technical requirements of Boots. Since the hydrolysis requirements of the boot and sole are mainly based on the properties of the polyurethane material, the requirements for polyurethane boots in ISO 20345: 2004 are used.
In terms of safety performance requirements, "Foot Protection Miner Safety Boots" is mainly for the risk factors commonly encountered by miners. Its oil resistance, leak resistance, toe protection, puncture resistance and antistatic properties are ISO. 20345: 2004 related requirements. Corrosion resistance is based on the national standard GB 20265-2006 "Chemical resistant industrial molded plastic boots" and GB 20266-2006 "chemical resistant industrial rubber boots".
In the antibacterial requirements, the antibacterial property of the boots adopts the QB/T 2591-2003 "Antibacterial plastic antibacterial performance test method and antibacterial effect", and according to the material properties, the antibacterial property of the boot pad is FZ/T 73023. AA grade requirements in Antibacterial Knitwear.
For the boot pad, the antibacterial requirement of light is not enough, and it must be hygroscopic and moisture permeable. Therefore, referring to the requirements of the insole in ISO 20345: 2004, the water absorption and hydrolysis absorbability are specified, so as to ensure that the boot pad absorbs sweat. And when the boots are not worn, let the sweat in the pad evaporate quickly, to ensure that the boots are dry and the bacteria are not easy to grow.
The reason why the "foot protection miners safety boots" stipulates that the antibacterial and deodorant requirements of safety boots are from the perspective of occupational health of workers. Because the miners wear safety boots for a long time, the sweat on the feet is difficult to dissipate. In addition, the interior of the boot system is exposed to sunlight for many years, which is prone to various types of molds, resulting in various types of ankles and athlete's foot.
Implementation points
Due to the particularity of the consumption pattern of protective equipment, it must be enforced in accordance with government regulations and standards.
The rapid development of economic globalization has brought pressure and challenges to the development of countries around the world, and has also pushed standard competition to the forefront of international market competition. The National Standards Committee encourages Chinese companies to participate more in standard setting, protect independent intellectual property rights, and achieve patent technology, patent standardization, and internationalization of standards. At this stage, this standard is issued as a safety production industry standard. When the time is ripe, the technical content and scope of this standard can be expanded, and new technologies are continuously incorporated into the standard.
The antibacterial requirements of "Foot Protection Miner Safety Boots" have never been stipulated in domestic similar standards. In fact, whether it is from the perspective of protecting workers' health or from the development trend of foreign standards, this performance requirement is necessary, and it should also be needed for safe production.
At the time of approval of the implementation of the "Foot Protection Miners Safety Boots", the national standard GB 21148-2007 "Personal Protective Equipment Safety Shoes" adopting international standards after revision was also released on November 1, 2007, and on June 1, 2008. Implemented on the day. The "Foot Protection Miner Safety Boots" standard is a powerful supplement to the GB 21148-2007 national standard. It is recommended that all testing organizations actively add corresponding testing equipment to cooperate with the implementation, so that the new standards can be applied to production, sales and use as soon as possible, so as to achieve both economic and social benefits.
