(2) Failure to perform timely operation or disposal after power failure will result in a chaotic production process or damage to valuable parts of the processing. For example, some processes in the chemical, petroleum industry, metallurgical, aerospace and other industries, steelmaking furnaces, metal melting casting, heat treatment and precision processing workshops.

(3) Places where lighting is extinguished will result in greater political impact or serious economic losses. Such as important communication centers, radio stations, television stations, power plants and central substations, control centers, national and international conference centers, important hotels, international terminals, transportation hubs, important power supply stations (heating, gas supply) , oil supply) and water supply facilities.
