Incorrect use of ESD products
1. Use ESD products as ordinary products. Many people use anti-static products as ordinary products. They think that anti-static products are just like ordinary products. As long as the products are not deformed or broken, they can still be used on the surface. This is a wrong understanding, such as preventing Electrostatic wrist strap generally last for only a few months. When they are used for a period of time, their appearance may not be damaged. However, after testing, they will find that wrist straps do not have antistatic properties. All anti-static products should be tested on a regular basis. Anti-static clothing should be cleaned and maintained and replaced regularly.
2, do not pay attention to socks and insoles. Workers wear socks or cushioned insoles when wearing anti-static shoes. For those who are prone to sweating, these socks and insoles will also conduct static electricity. For those who do not easily sweat, wear anti-static shoes. With mattresses and cushioned insoles, the socks and insoles cannot conduct static electricity, so that the body's static electricity cannot be introduced into the earth through the shoes. Therefore, a “human body comprehensive resistance tester” should be placed at the entrance of the machine room or factory building. The human body comprehensive tester can quickly and accurately detect those who wear unqualified anti-static shoes, socks, and cushioned insoles. Ling Yihao suggested that workers do not wear tweezers when wearing anti-static slippers in the summer, but they can wear cotton socks in winter but do not wear nylon socks.
3, ESD shoes and anti-static clothing only wear one. It is not right to wear anti-static shoes without wearing anti-static clothing, because ordinary clothing will also be highly charged with static electricity. In particular, most of the current clothing is chemical fiber, which can generate thousands of volts of static electricity, so it must be Wearing anti-static clothes can effectively isolate static electricity. It is also the same as wearing anti-static clothes without anti-static shoes. Experiments have shown that if the human body only wears anti-static clothing and does not wear anti-static shoes, the friction between ordinary shoe surfaces and the earth will still generate static electricity. The effect of anti-static electricity is very poor, so anti-static shoes can only be used to control the static electricity of the human body only with the use of anti-static clothing.
4, anti-static clothing and shoes are worn but there is no anti-static floor and do not wear anti-static wrist strap. Because the body's static electricity must be guided away from the anti-static shoes into the anti-static floor, or through the wrist strap into the earth, if the anti-static floor and anti-static wrist strap are not, then people's static electricity is also difficult to lead away. Therefore, it is best to have an anti-static floor and an anti-static wrist strap. At least, there must be an anti-static wrist strap.
5. Incorrect use of ESD wrist straps. ESD wrist straps are relatively easy to damage. Therefore, it is necessary to carry out tests every day. Moreover, some workers attach their anti-static wrist straps with a very loose cord and do not achieve anti-static effects. Therefore, the best method is to use an anti-static wrist strap for on-line monitoring. The instrument is monitored at any time. However, many companies do not even have an anti-static wrist strap tester. An anti-static wrist strap has been used until it is broken. It is very wrong.
The above 5 points are the common anti-static methods for workshops. Is there any successful bid for your workshop? Safety Working TECH warmly reminds you: Do not blindly use anti-static clothing, anti-static shoes, anti-static wrist strap, although anti-static products are easy to use, if you do not use the correct method of use, it will still lose its own anti-static effect
