Burning Hazard from Electrostatic Discharge Objects with static electricity must always be vented
.

There are two ways for the discharge of electric charge: one is natural escape; the other is different forms of discharge
.

Electrostatic discharge is a process by which electrical energy is converted into mature energy, and may ignite combustibles and become a source of fire or ignition
.

Therefore, anti-static is important in the process of production, transportation and installation.
Reasonable selection of anti-static workbench, anti-static packaging, and anti-static running tools are closely related to safe production
.

 　　For electrostatic discharge to become a source of ignition, the following conditions must be met: 1.
There is a source of static electricity; 2.
Static electricity is accumulated, and its electrostatic voltage is sufficient to cause electrostatic discharge; 3.
The energy of electrostatic discharge is sufficient to ignite flammable mixtures: 4.
Discharge occurs within the concentration range of the mixture
.

 　　I can see from the above conditions that ignition can occur only when the four basic conditions are met at the same time
.

From the perspective of eliminating electrostatic hazards, as long as any one of the conditions is destroyed, the purpose of preventing ignition can be achieved
.

 　　Safety limit of electrostatic accumulation 1.
Safety limit of electrostatic accumulation of conductors When a charged object is a conductor, it is generally considered that a dangerous situation is that a single electrostatic discharge can discharge almost all the stored electrostatic energy, and the electrostatic energy stored in the charged conductor is equal to or greater than When the ignition energy (or electrostatic induction) is small, there is a danger of electrostatic hazard accidents
.

 　　2.
The safety limit of electrostatic accumulation of insulators When a charged object is insulated, if a discharge occurs, under normal circumstances, the charged object will not release all the accumulated electrostatic energy, but partially release it
.

Therefore, the discharge safety limit of the charged object as an insulator cannot be obtained by the method used for the charged conductor
