According to the relevant fire laws and policies, the fire department does have the right to conduct fire safety inspections on residential buildings. According to local regulations, night inspection may vary from region to region. The purpose of the fire department is to ensure the fire safety of residential buildings, including problems such as irregular electricity consumption, and to prevent fire and other safety accidents. During the inspection, the fire department can check the power supply, wires and electrical equipment. In residential buildings, guide residents to use electricity reasonably and prevent fire according to regulations. However, the specific implementation also needs to refer to local policies and regulations and the actual work arrangements of the fire department. It is suggested that you can further consult the local fire department for more detailed and accurate information.
