At 8:28 on September 30, 2019, Zhangjiagang Ningxing Liquefaction Company, Jiangsu Province, when a Su BH5285 tanker was loaded with toluene, an explosion accident occurred, causing the death of the driver of the vehicle, Mr.
According to preliminary information, the accident was caused by an explosion that occurred during sampling after the loading platform was loaded.
It is reported that the specific cause of the accident is still under investigation.
How to prevent static electricity
Understand the hazards of static electricity
Understand the 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 prone to discharge due to its high voltage.
When a charged object and an object with an uncharged or low electrostatic potential are close to each other, if the potential difference reaches more than 300 V, a spark discharge will occur.
If the spark energy of electrostatic discharge has reached the minimum ignition energy of the surrounding combustibles, and the concentration of combustibles in the air reaches the explosive limit, it will burn or explode immediately.
(2) Harm to the human body
Electrostatic shock only occurs in an instant, the current passing through the human body is an instantaneous impulse current, and its hazards are mainly manifested in three aspects: direct injury, secondary injury, and mental stress.
When the human body suffers an electric shock, it will be mentally stressed, resulting in consequences such as misoperation, falling from a high altitude, injury or injury caused by touching the machine.
(3) Hazards of electrostatic production environment, etc.
Static electricity can deposit powder in production, block pipes, sieve holes, etc.
, cause poor transportation and cause the system to hold back pressure, and overpressure can cause equipment to rupture.
In the process of storing and transporting plastics and other products, electrostatic discharge can cause melting, bonding, discoloration, decomposition, deterioration, and scrapping of the products.
Electrostatic discharge energy may cause damage to silicon components in computers, production control instruments, and safety control systems, causing misoperation and causing accidents.
