What harm does static electricity do to people?

1, explosion and fire

Explosion and fire are the biggest hazards of static electricity. Although the electrostatic energy is not large, it is easy to discharge because of the high voltage. When the charged body and the uncharged or low electrostatic potential are close to each other, if the potential difference reaches above 300V, spark discharge will occur.

If the spark energy of electrostatic discharge reaches the minimum ignition energy of surrounding combustible materials and the concentration of combustible materials in the air reaches the explosion limit, it will burn or explode immediately.

2. The harm of electrostatic shock to human body

Electrostatic shock only happens in an instant, and the current passing through human body is instantaneous impact current, and its harm is mainly manifested in three aspects: direct injury, secondary injury and mental stress. When people get an electric shock, they will be nervous, and there will be consequences such as misoperation, falling, falling or touching machinery.

3. Hazards of electrostatic production environment, etc.

Static electricity will deposit powder in production, block pipes, sieve holes and so on. , leading to poor pressure suppression of transportation and system, and overpressure will lead to equipment rupture. During the storage and transportation of plastics and other products, electrostatic discharge will lead to melting, bonding, discoloration and even decomposition, deterioration and scrapping of products. Electrostatic discharge energy may lead to the damage of silicon components in computers, production control instruments and safety control systems, resulting in misoperation and accidents.

Extended data:

How to prevent static electricity in the workplace;

1, grounding method: This is the simplest method to eliminate electrostatic hazards, mainly used to eliminate static electricity on conductors, not on insulators;

2. Leakage method: using humidifiers and antistatic additives to promote the self-elimination of electrostatic charges of insulators;

3. Electrostatic neutralization: try to generate charged ions in places with dense electrostatic charges to neutralize the electrostatic charges there; This method can eliminate static electricity on insulator;

4. Process control method: Measures such as reducing material flow and increasing water content can be taken.

People's Network-It's all caused by static electricity. Electrostatic hazard is so great, please take precautions!
