This thing is so dangerous!

Static electricity - natural physical phenomena
Static electricity is a charge that is at rest. In dry and windy autumn, people often encounter this phenomenon in daily life: when they undress and sleep at night, they often hear the sound of snoring in the dark, accompanied by blue light. When they meet hands, they just touch the finger. The other party will suddenly feel the tingling of the fingertips, which is very shocking. When you comb your hair in the morning, the hair will often "float". The more you mess, the more you will pull the door handle and the faucet will "electric shock", often issued The sound of "啪, 啪, 啪", this is the static electricity that occurs in the human body.

Remember the white sweater big sister at this gas station?
When the weather is dry, undressing will hear the sound of “small smashing” and sparks appear, which reminds people that the static and winter season has come.
The weather is dry in autumn and winter, especially when the rainfall is reduced, it is easy to generate static electricity, causing fire, explosion and personal injury accidents. Static electricity will accumulate on metal equipment, pipes, and containers to form a high potential. Although the static electricity itself is not large, it is easy to discharge due to its high voltage. The spark of electrostatic discharge will cause burning or explosion, resulting in loss of personal and property.

Electrostatic accident
On November 20, 2012, a hardware product company in Shenzhen, Guangdong Province, the aluminum dust concentration in the workshop was too high, causing an explosion caused by static electricity, causing seven workers to be injured.
On May 8, 2012, the paint shop of Beijing Hyundai First Plant caught fire and the area of ​​fire was 100 square meters. The cause of the fire was triggered by static electricity.
On December 1, 2014, Samsung Latex Co., Ltd. in the chemical market of Wenzhou City, Zhejiang Province, caused a fire accident due to static electricity during the vinyl acetate unloading process.
Static electricity is a charge that is at rest. According to different substances with static electricity, static electricity can be divided into solid static electricity, powder static electricity, liquid static electricity, gas static electricity and human body static electricity.
The accumulation of static electricity is silent, but once it is triggered to generate a discharge, the possible harm can not be underestimated. The main hazard of static electricity is fire and explosion; it can easily cause malfunction of precision electronic equipment because static electricity can break through the integrated original.

Which places need anti-static
　
1. Locations for the production, use, storage, loading and unloading of inflammable and explosive materials;
2. Production equipment for producing flammable dust, dry trapping method, and places for loading and unloading such materials;
3. Loading and unloading places for flammable gases, flammable liquid tankers and ships;
4. A place where electrostatic shock can cause harm.

How to prevent static electricity in the workplace
1. Grounding method: It is the simplest method to eliminate static electricity. It is mainly used to eliminate static electricity on the conductor and should not be used to eliminate static electricity on the insulator.
2, leakage method: the use of moisturizing agents and the use of anti-static additives, to promote electrostatic charge from the insulator itself.
3, static neutralization method: in the place where the electrostatic charge is dense, try to generate charged ions, neutralize the electrostatic charge. The electrostatic neutralization method eliminates static electricity on the insulator.
4, process control method: try to reduce the material flow rate, increase water content and other measures.

How to remove static electricity at home
1, wash hands and wash your face. After watching TV and computer, you should wash your face and wash your face immediately, so that the static electricity on the surface of the skin is released in the water;
2. Try not to wear chemical fiber clothes in autumn and winter. When you usually wear clothes, try to choose cotton-like clothes;
3. Touch the wall to remove static electricity. When we want to touch other people or metal conductors, just touch the wall first, or touch the handle with a metal key, and then touch it with your hand, it will not be charged;
4, before combing the hair, the comb can be used to prevent static electricity. Or switch to a wooden comb and a horn comb;
5, indoors must maintain a certain degree of humidity. Indoors should be mopped, diligently sprinkled with water, or humidified with a humidifier.

How to prevent static electricity during refueling
1. Find a staff member to cheer or ask for supervision. If you are in a hurry or want to try self-help, you can ask the staff to help with supervision and avoid mistakes.
2. Do not use electrical equipment such as mobile phones. Do not take unsafe behaviors such as tapping clothes and combing with a chemical fiber comb that is prone to static electricity.
3. Discharge before refueling. The self-service dispenser has a keyboard for inputting information. Its material is metal and it is in direct contact with the ground. When the owner inputs his own fueling information before refueling, the static electricity carried by the body is released and discharged.
4. Do not return to the car during the refueling process. Turn off the engine after parking, do not smoke and use the mobile phone; do not leave the oil gun during the refueling process, and do not return to the car to prevent static electricity from coming back again.
5, pay attention to the use of a good fuel gun. Before refueling, the fuel gun should be lightly touched at the fuel tank mouth to eliminate static electricity. Secondly, when the fuel is refueled, the oil gun should be as deep as possible to the tank mouth. This can reduce the volatilization of gasoline vapor, which is equivalent to reducing the ignition medium from the source.
6, do not rush to pull the oil gun after adding oil. After the oil is added, many car owners can't wait to pull out the oil gun. This is actually a mistake and it is easy to cause a fire. Because there are residual oil droplets on the head of the oil gun at this time, not only will it cause waste, but it may also drip into the car to pollute the car and even cause fire.
7. In case of fire at the oil gun mouth, the owner should not panic. Stop the refueling operation immediately, then keep the refueling muzzle away from the oil source and quickly extinguish the fire with a fire extinguisher. The lack of air in the fuel tank will not enter the fire tongue. tank. Once the fire is over, the fueling gun should be taken out of the fuel tank immediately. Otherwise, it is very likely that the oil and gas will contact the outside air to cause a larger fire and even cause an explosion.

How to prevent static harassment by driving
1. Keep your skin moist. When the fall is over, drink plenty of water and apply more moisturizer to increase the surface moisture of the skin and reduce the generation of static electricity. Wash your hands before driving, or put your hands on the wall to remove static electricity.
At the same time, before driving, the owner can use small metal items such as keys, cotton rags, etc. to first touch the door, instrument panel, seat and other positions to achieve the purpose of eliminating static electricity.
2. Use less chemical fiber products. You can put a wet towel on the instrument panel, and increase the humidity inside the car through the evaporation of water in the towel to reduce the generation of static electricity. If conditions permit, the owner can install a car humidifier in the car. When driving, try to open the inner circulation air conditioner as much as possible, because the inner circulation air conditioner makes the already dry environment of the vehicle lose water faster.
3. Use an electrostatic discharge device. When dealing with static electricity, the owner can also try the electrostatic discharge device. There are electrostatic discharge devices, electrostatic discharge bars, electrostatic tapes, electrostatic stickers, static keyless buttons, etc. commonly found on the market.
4, anti-static maintenance products. The owner can use some antistatic agent in the car carpet, instrument panel and other locations. When in use, it can be sprayed directly on the conductive part, and then wiped with a dry cloth, not only can prevent static electricity, but also effectively reduce the generation of dust and dirt. In addition, the choice of anti-static car wax is also a good choice.
For special places, in order to prevent static accidents, avoid flammable dust, gas, and leakage into the air.

The staff should also: in the place where the human body must touch, the contact rod should be touched by hand at any time to remove static electricity from the human body; wear anti-static shoes, overalls and gloves, and it is forbidden to wear or use chemical fiber products; Metal items.

Old driver reminds: Autumn and winter season should pay more attention!
