Static electricity hazards:
1. Explosion and fire?
Explosion and fire are the biggest hazards of static electricity. Although the electrostatic energy is not large, it is prone to discharge due to its high voltage. When a charged object and an uncharged object or an object with low electrostatic potential are close to each other, if the potential difference reaches more than 300V, spark discharge will occur.
If the spark energy of electrostatic discharge reaches the minimum ignition energy of the surrounding combustibles, and the concentration of the combustibles in the air reaches the explosion limit, combustion or explosion will occur immediately. ?
2. What is the harm of electrostatic shock to the human body?
Static electric shock only occurs in an instant. The current passing through the human body is an instantaneous impact current. Its harm is mainly manifested in three aspects: direct Injury, secondary injury, mental stress. When the human body suffers an electric shock, it will cause mental stress, resulting in consequences such as misoperation, falling from a height, injury from falling or contact with machinery, etc. ?
3. What are the hazards of static electricity in the production environment?
Static electricity can deposit powder in production, block pipelines, sieve holes, etc., resulting in poor transportation and pressure suppression in the system. Overpressure can cause equipment to rupture. During the storage and transportation of plastics and other products, electrostatic discharge can cause the products to melt, stick, discolor or even decompose, deteriorate, and be scrapped. Electrostatic discharge energy may cause damage to silicon components in computers, production control instruments, and safety control systems, causing misoperation and accidents.

How to prevent static electricity in the workplace:
1. Grounding method: This is the simplest method to eliminate static electricity hazards and is mainly used to eliminate Static electricity on conductors should not be used to eliminate static electricity on insulators;
2. Leakage method: Use humidifiers and antistatic additives to promote the elimination of static charges from insulators;
3. Electrostatic neutralization method: Try to generate charged ions in areas with dense electrostatic charges to neutralize the electrostatic charges there; this method can eliminate static electricity on insulators;
4. Process control Method: Measures can be taken to reduce the material flow rate as much as possible and increase the water content.
People's Daily Online - It's all caused by static electricity. Static electricity is so harmful. Please take precautions like this!
