Pay attention to the refrigerant in the refrigerator when repairing it, which is harmful to people, but it will not be harmful as long as the method is proper.
Don't maintain the refrigerator for a long time when it is running. When the refrigerator is running, the cooling pipe at the back or below releases a strong magnetic field. In addition, too much dust in the cooling tube of refrigerator will also affect electromagnetic radiation. The more dust, the greater the electromagnetic radiation. Magnetic field will affect people's nervous system and physiological function. Electromagnetic waves have strong penetrating power and penetrate deep tissues and organs through the body surface. People usually don't pay attention to it. Once the superficial tissue pain occurs, it means that the deep tissue or organ has been seriously damaged.
