The harm of static electricity to human body
Researches on human electrophysiology showed that the average current of humans is 1.1mA for adult males and 0.7mA for adult females; the current is 16mA for adult males and 10.5mA for adult females. When the electric shock current is greater than the escaping current, the electric shocker cannot take the initiative to get rid of the power source. If there is no external help, the electric shock time will be prolonged and the risk of death will occur. The hands and feet are the parts where electric current passes through the human body * and is prone to injury.
The damage of static electricity to the human body is caused by psychological obstacles and fear, which can lead to accidents. It can also cause skin ** and dermatitis due to electrostatic shock. The main hazard of static electricity is the occurrence of flammable and explosive accidents in the industry, thereby endangering the lives of operators and causing major losses in production facilities.
Electric shock injury is a common industrial injury accident, which can be divided into contact electric injury and non-contact electric injury. The former is mainly caused by electric current, which can damage the internal tissues of the human body, such as the heart, respiratory system, nervous system and so on. The mild ones have acupuncture, shock, tremor, cramps, increased blood pressure, irregular heart rate and coma; the severe ones may have ventricular fibrillation, cardiac arrest, respiratory arrest and even death. The latter is mainly caused by arc damage, which is manifested by electric branding, electric **, and skin carbonization. In severe cases, it can reach the muscles, bones and internal organs.
Electrical performance protective shoes are protective shoes used to protect the feet in personal protective equipment, including anti-static shoes and conductive shoes, which can prevent static electricity injuries and electric shock injuries.
