In recent years, as the bathroom is a place where accidents are likely to occur, kitchen and bathroom products have begun to receive people's attention, and the safety of many building materials such as tile floors has been considered more. And we often hear reports about electric shocks caused by electric shocks in the bathroom when bathing. It seems that the anti-electric shock device in the bathroom should not be underestimated.
Cause of electric shock
The main cause of such an electric shock accident is that the impedance of the human body drops drastically. It turns out that when the human body is dry, the body's resistance is relatively large, usually around 2000 ohms. At this time, if there are tens of volts of voltage passing through the human body, at most, it will feel a little numb, and there will be no other problems. But after showering, it is different. After the shower, the body is soaked and the body impedance is greatly reduced. At this time, the resistance may be only 100~200 ohms. At this time, the voltage that is introduced into the bathroom along the metal pipe is only one or twenty volts, which is enough to cause ventricular fibrillation and death. The bathroom is usually equipped with a bathtub or a bathtub. The indoor environment is relatively humid, and there is a high possibility of electric shock.
Measures to prevent electric shock
The mandatory provisions of the new norm clarify the status of "equal potential" and the importance of the state's attention to this issue. "Local equipotential bonding" in the bathroom can make the bathroom at the same potential, which helps to reduce the potential difference and prevent dangerous contact voltage. When making equipotential bonding, it is necessary to ensure reliable conduction of equipotential bonding. In addition, by adopting the equipotential bonding, the grounding is actually realized, because the pipe and the basic steel bar connected by itself play a grounding role of low resistance and long life, which is far better than the artificial grounding device that was specially driven into the ground in the past.
Auto Lock Steel Measuring Tape
Auto Lock Steel Measuring Tape
The telescopic tape can reliably and automatically lock and return the button without twisting to extend the distance, and it can be immediately drawn into a small shell.
It is suitable for kitchens, garages, manufacturing factories, steel factories, hardware stores, etc. it can be used to measure the length and width of measuring tools or casting aircraft, machines, furniture, etc., and it can be used to measure the accurate large tape.
