Static electricity is harmful to human health. According to the Health News, patients with neurasthenia, hypertension, heart disease and mental illness, especially those with cardiovascular and cerebrovascular diseases, should take proper precautions against static electricity.
This is because the cardiovascular system of middle-aged and elderly people is aging and their anti-interference ability is weakened. External electrostatic interference often leads to arrhythmia, tachycardia, premature beats and even atrial fibrillation. Studies have shown that static electricity is more harmful to the elderly and pregnant women. It can interfere with the membrane potential of red blood cells, cause red blood cells to gather in blood vessels, and make middle-aged and elderly people prone to myocardial infarction or cerebral thrombosis.
Static electricity can reduce the level of progesterone in pregnant women, and then lead to abortion or premature delivery; Static electricity can inhibit the production of sex hormones in middle-aged and elderly men, causing premature aging and male sexual dysfunction. In addition, static electricity can also cause skin dryness, allergies, itching, erythema and pigmentation.

Hazards of static electricity:
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 a charged body and an uncharged or low electrostatic potential are close to each other, if the potential difference reaches more than 300 V, 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.
People's Network-It's all caused by static electricity. Electrostatic hazard is so great, please take precautions!
People's Network-Being "shocked" by static electricity is just a small problem? The harm of static electricity is not small
