People in anti-static areas wear anti-static wrist straps
Anti-static wrist strap is an indispensable part of our static monitoring system. It is mainly used to protect the human body from static electricity. At the same time, it is also one of the commonly used anti-static equipment. New employees will receive anti-static training when they first enter the job. Anti-static wrist strap training, we all know that the human body is easy to generate static electricity at work. The training of anti-static wrist straps is particularly important. Let me have an anti-static wrist strap training with me today!
Classification of anti-static wrist straps and their use in anti-static factories: Anti-static wrist straps are generally divided into wired and wireless wrist straps. Wired wrist straps are divided into single-loop wrist straps and double-loop wrist straps according to their loops. They are often used in anti-static factories for static protection of workers at fixed positions (such as production line employees). It is characterized by a wire connected to the ground wire, which can quickly remove the human body. The generated static electricity is exported. If an anti-static wrist strap monitoring device is installed, after an abnormal alarm occurs, relevant staff will take repairs, replacements and other methods to restore it. For the factory area without first shutting down the monitoring equipment, in order to ensure the effective implementation of anti-static Perform a test every hour and record it.
Wireless wrist straps are divided into cutting-edge discharge wireless wrist straps and loop power-consuming wrist straps. They are often used for mobile workers (such as inspectors, managers, etc.) in anti-static delivery rooms. They are characterized by no wire constraints, convenient movement back and forth, and slow discharge , The cutting-edge discharge wrist strap needs to reach a certain voltage before it can discharge. At the same time, there is no detection method for wireless wrist straps. In the electrostatic factory area, it needs to be replaced every three months. The relevant personnel shall supervise and record.
How to wear an anti-static wrist strap:
1. Check that the metal part of the wrist strap should be free of dirt, corrosion, etc.; the connection buckle should be flexible and reliable.
2. Place the metal exposed surface of the wrist strap against the skin of the wrist and wrist, so that at least 80% of the metal surface is in contact with the skin;
3. When adjusting the elastic band or Velcro, the tightness is moderate, comfortable and flexible.
4. It is not allowed to wear the wrist strap through a shirt, wrist brace, rubber cord, etc. without reliable contact with the skin.
5. The ground wire of the wrist strap should be reliably connected to the working ground wire.
Detection method of anti-static wrist strap:
1. Check the calibration label of the electrostatic wrist strap detector, and it should be within the validity period of the approval;
2. Connect the banana head of the calibration line equipped with the tester to the tester, hold the other end in your hand, and press the test metal body with the other hand, the red indicator light of the instrument "LOW" should light up; disconnect the calibration line and use Press the test metal body with one hand, and the red indicator light of the instrument “HIGE” should be on, which indicates that the tester is basically normal and ready for use;
3. Connect the banana head of the calibration line of the tester to the tester, and connect the other end to the working ground reliably. The user of the tested wrist strap is required to press the test metal body naturally with the palm of the hand. At the same time the buzzer sounds, it means that the wrist strap is well grounded; otherwise, it will be regarded as bad.
