The fire safety inspection system aims to prevent and reduce the harm caused by fires, ensuring that building fire safety facilities can fully perform their fire prevention and extinguishing functions, and effectively guarantee building fire safety. This system is a technical inspection mechanism for building fire safety facilities established in accordance with the relevant requirements of the "Fire Protection Law of the People's Republic of China," Order No. 30 of 1996. "Regulations on the Supervision and Review of Fire Protection in Construction Projects," and Document No. 21 of 1996 (Public Security Bureau Circular) "Notice on Accelerating the Establishment and Implementation of a Management System for the Inspection, Repair, and Maintenance of Building Fire Safety Facilities."
The Municipal Fire Bureau issued a notice regarding the technical inspection of building fire safety facilities and the issuance of fire safety facility certificates (plates). The notice clearly stipulates that for newly built, renovated, or expanded construction projects, before the building fire safety facilities are put into operation after completion, a technical inspection must first be conducted by a qualified testing agency. After the inspection is qualified, the fire department will conduct an acceptance inspection, and a fire safety facility certificate (plate) will be issued upon successful completion of the acceptance inspection. If the project has not been inspected or the inspection results are unqualified, the fire department will not conduct the acceptance inspection, and the project shall not be put into use. In addition, a regular annual inspection system is implemented for building fire safety facilities already in use. All building fire safety facilities within the administrative area of the city must undergo a fire safety technical inspection every year.
Fires occur almost every day in the world, making timely prevention before a fire occurs particularly important. Given the importance of fire safety inspections in daily life, what are the specific inspection contents?
