Yes! Static electricity is definitely harmful for us but not causing death. After all, the voltage of static electricity can up to tens of thousands of volts even hundreds of thousands of volts which is able to discharge on the spot and generate electrostatic spark.

For instance, the electrostatic interference of skin can change the normal potential difference (PD) of human body surface where it has an awful influence of cardiac muscle’s normal electrophysiological progress which tends to make the patient gets worse.

Therefore, in those easy-to generate electrostatic’s operation, it is quite necessary to install a terrific GND device in order to let out stacked electrostatic promptly.
