What are the requirements for wearing anti-static shoes
Clean shoes and anti-static shoes are also required to wear. In general, under what circumstances do we wear them, and the wearing places are also very demanding. So where are dust-free shoes and anti-static shoes suitable for wearing?
skills requirement:
1. Where to wear
2. Clean shoes and anti-static shoes
dust-free shoes, anti-static shoes are mainly used in places that may cause burning and explosion due to static electricity on the human body (for example, certain places in rubber, chemical, printing, medical, electronic and other industries). At the same time, it can also avoid electric shocks and fires accidentally caused by electrical equipment below 250V.
3. It is forbidden to wear dust-free shoes and anti-static shoes for workers who are in danger of electric shock when maintaining power equipment or handling high-voltage electrical equipment.
4, performance index
5. Electrical performance indicators
During the wearing of the shoes, measure according to GB4386-84 "Dust-free shoes, anti-static shoes, conductive rubber-soled shoes resistance value measurement method". The resistance of the anti-static shoe sole of dust-free shoes must be in the range of 0.5×10^5Ω to 1.0×10^8Ω.
Anti-static shoes
1, other performance indicators
2. Other performance requirements of dust-free shoes, anti-static shoes, and conductive rubber-soled shoes must meet the national standards and technical requirements of the corresponding footwear.
3. When designing the structure of dust-free shoes, anti-static shoes and conductive rubber-soled shoes and selecting materials, it must be considered to minimize the change in the resistance of the bottom of the shoe under the influence of wear and pollution.
4. For dust-free shoes with special requirements, anti-static shoes and conductive rubber-soled shoes (for example, they need to be resistant to acid, alkali, oil, etc.) should also meet the corresponding technical standards.
Wearing requirements:
1. In order to ensure the effect of eliminating static electricity on the human body, when wearing anti-static shoes, the resistance of the ground should not be greater than 1.0×10^8Ω; when wearing conductive rubber-soled shoes, the resistance of the ground should not be greater than 1.5×10 ^5Ω.
2. In the process of wearing shoes, the bottom of dust-free anti-static shoes and conductive rubber-soled shoes must not be stained with insulating impurities.
3. In the process of wearing shoes, pay attention to avoid wearing thick socks with strong insulation or wool, and insulating insoles at the same time.
