Tips for indoor lightning protection

TV set

For TV sets, lightning can enter the TV set from the power supply or from the outdoor antenna or CCTV signal cable. Therefore, do not use the TV on thunderstorm days. Unplug the power plug and unplug the outdoor antenna, which cuts off the way the lightning enters the TV, ensuring safety.

Other household appliances

Household appliances such as refrigerators, air conditioners, washing machines, etc., should be cut off the power and unplugged from the socket when they encounter intense lightning activities. It is not safe to just cut off the switch.

phone

Under normal circumstances, the input port of the telephone line has a protector to prevent abnormal voltages, and it is relatively safe to make calls. However, if lightning strikes very close to the telephone line, and the protector is not disconnected from the telephone line, a strong abnormal voltage will invade, which may cause harm to the telephone and the human body. Therefore, in strong thunderstorm weather, it is better not to call for personal safety.
