Static hazards:
1, explosion and fire?
Explosions and fires are the biggest hazards of static electricity. Although the electrostatic energy is not large, but because of its high voltage and easy to discharge. When the charged body and the uncharged or electrostatic potential low objects close to each other, if the potential difference reaches more than 300V, there will be a spark discharge.
Spark energy of electrostatic discharge, if it has reached the minimum ignition energy of the surrounding combustible materials, and combustible materials in the air when the concentration reaches the explosion limit, it will immediately burn or explode.?
2, electrostatic shock on the human body harm?
Electrostatic shock occurs only in an instant, the current through the human body for the instantaneous impact current, the harm is mainly manifested in three aspects: direct harm, secondary injury, mental tension. The human body suffers from electric shock, will be nervous, the occurrence of misuse, fall from height, fall or touch the machinery causing injury and other consequences.?
3, static electricity production environment and other hazards?
Static electricity can make the production of powder deposition, clogging pipes, sieve holes, etc., resulting in poor transportation caused by the system holding pressure, overpressure can lead to equipment rupture. Storage and transportation of plastics and other products in the process, electrostatic discharge can lead to product melting, bonding, discoloration or even decomposition and deterioration, scrap and so on. Electrostatic discharge energy may lead to computers, production control instruments, safety control systems in the silicon components damage, causing misuse and accidents.

How to prevent static electricity in the workplace method:
1, grounding method: this is the simplest way to eliminate static hazards, mainly used to eliminate static electricity on the conductive body, should not be used to eliminate static electricity on the insulator;
2, leakage method: the use of humidifying agents and the use of anti-static additives to promote static electricity charge from the Insulator to eliminate themselves;
3, electrostatic neutralization method: in the electrostatic charge in a dense place managed to produce charged ions, the electrostatic charge will be neutralized; this method can be eliminated on the insulator electrostatic;
4, the process control method: can be taken to minimize the flow rate of the material to increase the water content and other measures.
