The equipment is sensitive to ambient temperature, humidity, state of air medium and other conditions. For example, moisture, conductive dust, corrosive vapor and gas damage the insulation of electrical equipment, thus greatly reducing its insulation resistance, which may bring dangerous voltage to the shell, base, hood and other metal parts of electrical equipment, resulting in electric shock accidents. In this case, if the ambient temperature is high, the human body resistance will also be reduced, thus increasing the risk of electric shock. There are metal grounding objects near conductive floors and electrical equipment, which will increase the risk of electric shock. In this case, whether the human body directly contacts the charged body or accidentally contacts the charged body, it is easy to form a current circuit, and a large current may flow through the human body.
