How can static electricity accidents be prevented? Answer: 1. Limit the flow rate of liquids. 2. Employ electrostatic shielding. 3. Ensure proper grounding; grounding wires can help dissipate or eliminate accumulated charges. 4. Increase conductivity, raise air humidity, and use electrostatic additives. 5. Avoid or prevent hazardous factors in the surrounding environment, restrict the use of or remove hazardous substances, improve ventilation conditions, and replace or fill with inert gases. http://down.hcbbs.cc/attachment/forum/201706/10/203353z7y06fdo70r6eod0.jpg The petrochemical industry – innovative ideas for energy savings in the “Creative Thinking” campaign (the second phase is currently in progress). http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1666758 (Source: Haichuan Chemical Industry Forum) “My Technical Upgrades” in the coal chemical industry in 2017. http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Industry Forum website)
1. Wear more cotton clothing: Cotton garments generate much less static electricity compared to woolen or synthetic fibers. 2. Wear woolen clothing containing fine metal wires: Since the conductive wires can make contact with the human body, they help to neutralize the opposite charges that are generated between them. 3. Wear anti-static shoes with conductive soles: The static electricity generated is continuously discharged. 4. Increase the contact area: If charge has accumulated on our bodies, we can release it by simply \"grounding\" the body, for example by washing our hands, touching pipes, faucets, or other metal objects that are grounded. 5. Touching metal with the key on the handle: In winter, if you’re worried about static electricity when opening a door, touching the door with the key can help discharge that electricity; the point of contact for discharge isn’t necessarily a specific spot on your fingers.
In areas prone to static electricity, keep the floor moist or cover it with a surface that has good electrical conductivity； Staff must wear anti-static clothing as well as shoes and boots to allow static electricity to be discharged into the ground promptly, thereby preventing its accumulation and the generation of sparks. 1) Reduce static electricity generation; 2) Control the flow rate of oil; 3) Grounding and bonding; 4) Control the method of refueling; 5) Prevent oil mixing or contamination with water

1. Limit liquid flow rate； 2. Adopt electrostatic shielding ； 3. Reliable grounding – the grounding wire helps to dissipate or eliminate accumulated charge ； 4. Increase conductivity, raise air humidity, use static electricity additives ； 5. Avoid or prevent hazardous factors in the surrounding environment, restrict the use of or remove hazardous substances, improve ventilation conditions, and replace or fill with inert gases.
Eliminate static electricity and prevent its occurrence; for example, implement static grounding during the loading and unloading of liquefied gas, and use static bonding wires to connect the flanges together
Ensure proper electrical grounding protection and check insulation
