In winter
Static electricity is everywhere
When you take off your sweater
When you get into the bed
Even open the door and touch the doorknob
are often subjected to "electric shocks"
Do you know static electricity
It can also cause fires

Recently, Hanzhong, Shaanxi
A car 4S shop in the repair room
A fire broke out
Firefighters arrived at the scene and extinguished the fire in time
Fortunately, there were no casualties
After investigation, the cause of the fire was:
Workers generate static electricity during car repairs
Causing the vehicle to catch fire
Electrodes in production may become
The "culprit" that started the fire
Related Cases
On October 5, 2023, an explosion occurred in the workshop of a company in Shizuishan, Ningxia, and nearly 100 commanders and fighters from 23 local fire trucks rushed to the scene to carry out rescue. The direct cause of the accident was due to the leakage of materials in the workshop, coupled with the explosion accident caused by static electricity in the workshop.
On May 21, 2023, a deflagration accident occurred in a company in Chuzhou, Anhui Province, resulting in one death and a direct economic loss of about 3.574 million yuan. The direct cause of the accident was the deflagration of the static electricity generated when ethyl acetate flowed at high speed during the preparation of the glue by the operator.
On the morning of June 30, 2020, an explosion accident occurred in workshop 103 of Jiangxi Songda No. 1 Company, resulting in one death and a direct economic loss of about 830,000 yuan. The direct cause of the accident was that the concentration of crude gas after the leakage reached the explosion limit, and the flash explosion was caused by static electricity.
How exactly is static electricity generated
And why is it easy to "ignite"

Where does the static electricity come from?
When clothing and other items on a person's body rub against each other, static electricity is generated that adheres to the human body. Generally speaking, clothing made of chemical fibers is more likely to generate static electricity, while cotton clothing produces less static electricity. Because the winter is dry, it is more conducive to the transfer and accumulation of electric charge, so people will feel that the static electricity on the body is greater in winter.
Where is static electricity easy to "ignite"?
When the static electricity on the person is charged, there will be a spark discharge, and there are many flammable particles in the air of factories and gas stations, providing a flammable environment, just like a lighter, resulting in a fire. In places such as paper mills, flour mills, and grain processing plants, dust particles gathered in the air may also cause explosions when they encounter electrostatic sparks.
In winter, the weather is dry
To avoid static electricity "ignition"
Please keep these "power avoidance" tips in mind
