Prevent home appliances from leaking and check the grounding line regularly

On July 15, a university student accidentally died of electric shock when taking a bath (for details, see the newspaper A10 on July 19th). The cause of death of the deceased was suspected as electric water heater leakage.

“The kitchen and bathroom of each household is the most dangerous place.” On July 19, Zhao Yong, deputy monitor of the maintenance class of the Jiangnan branch of the Nanning Power Supply Bureau, introduced that the kitchens and bathrooms are generally equipped with refrigerators, microwave ovens, washing machines, and electric water heaters. These two places are often the wettest places in the home, and the humidity is harmful to home appliances.

According to Zhao Yong, electric water heaters rely on electric heating rods to generate heat. Under normal circumstances, electric heating rods will have a small resistance and will not leak electricity. But if the resistance is broken down by the current, the water in the water heater is charged. The charged water is directly sprayed on the human body, and electricity flows through the human body into the floor to form a circuit, which leads to human body's electric shock. "When you take a bath, many people are accustomed to washing their heads first or flushing their heart sockets first. This will make electric shock more dangerous."

He said that in order to avoid "discharge" of home appliances, the public should use electrical appliances safely. For most kitchen and toilet appliances, the appliance should be turned off and power off immediately after use. At the same time, to prevent the environment from getting wet, it is recommended that members of the public try to place small household appliances away from water or in wet environments, or place some insulation underneath household appliances.

When purchasing an electric water heater, the public can choose some products that have “electric wall protection” devices. “The principle of the wall is simply equivalent to installing a large resistance between the human body and the water.” Zhao Yong said that in the event of a leakage, the resistor can take most of the voltage and thus the voltage the human body will bear. The human safety voltage is much lower than 36V.
