靜電的危害來自于帶電體的相互作用。當飛機機身與空氣、水蒸氣、灰塵等顆粒摩擦時，會使飛機帶電。如果不采取措施，將嚴重干擾飛機無線電設備的正常工作，使飛機變聾變瞎。在印刷廠，書頁之間的靜電會使書頁粘在一起，難以分離，給印刷帶來麻煩；在制藥廠。因為靜電會吸引灰塵，所以藥物的純度不會達標；電視開機時，屏幕表面的靜電容易吸附灰塵和油污，形成灰塵膜，降低圖像的清晰度和亮度；混紡衣服上常見的難以拍掉的灰塵，也是靜電夯的鬼。

　　The second biggest hazard of static electricity is that it may explode because of the ignition of some flammable objects by electrostatic sparks. In the dark night, when we take off our nylon and woolen clothes, there will be sparks and "beep" sounds, but this is basically harmless to the human body. However, on the operating table, except for electric spark, it will cause the explosion of anesthetic, which will hurt doctors and patients; In coal mines, it will cause gas explosion, which will lead to the death and injury of workers and the mine will be scrapped.
