2022, a particularly serious collapse accident occurred in Panshuwan Group, Jinping Community, Jinshanqiao Street, Wangcheng District, Changsha City, Hunan Province, resulting in 54 deaths and 9 injuries, with a direct economic loss of 90.7786 million yuan.
Recently, the executive meeting of the State Council deliberated and approved the investigation report on the collapse accident of the "4.29" particularly serious residential self-built houses in Changsha, Hunan Province. According to the investigation by the accident investigation team of the State Council, the collapse accident of the "4.29" particularly serious residential self-built house in Changsha, Hunan Province, was caused by the owner's illegal construction, story-adding expansion and rental operation, and the local Party committee government and its relevant departments were not responsible for organizing the renovation of illegal buildings and the investigation and management of potential risks, and some even shirked their responsibilities. Major potential safety hazards have not been rectified for a long time, resulting in particularly serious accidents of production safety responsibility. The direct cause of the
accident was the poor quality, unreasonable structure, poor stability and low bearing capacity of the original five-storey (local six-storey) building constructed in violation of laws and regulations. After the illegal addition and expansion to the eighth storey (local nine-storey), the load increased significantly, resulting in the columns and walls on the east side of the second storey exceeding the ultimate bearing capacity, resulting in compression damage and continuous development. Eventually, the whole house collapsed. Before the accident, in the case of obvious signs of collapse, the owner refused to listen to advice and did not take emergency evacuation measures, which was an important cause of casualties. The Central Committee of the Communist Party of China (CPC) attached great importance to the collapse of a particularly serious residential self-built house on April 29
in Changsha, and immediately deployed on-site rescue, treatment of the wounded, and investigation and disposal of the accident. The investigation found that there were some problems in Hunan Province, Changsha City, Wangcheng District and relevant departments, such as slow and simple deployment of centralized management, mutual prevarication and avoidance of contradictions in daily supervision, careless investigation and rectification, inadequate investigation and punishment of violations of laws and regulations, confusion in the management of housing inspection institutions, and out-of-control of the source of self-built housing planning and construction. There are relevant violations of laws and regulations by the owners and enterprises involved. In accordance with the administrative authority of cadres, the discipline inspection and supervision organs of
Hunan Province have seriously pursued the accountability of 62 public officials suspected of violating discipline and law in the accident in accordance with the rules and regulations.

What are the potential safety hazards
of self-built houses?
1. Construction safety: In the construction process of self-built houses, there are often no professional engineers to monitor and manage, and the tools and materials used may have problems, which may lead to safety accidents;
2. Structural safety: the structural design of self-built houses is often not subject to professional verification, and if the design is unreasonable, there may be potential safety hazards such as collapse and collapse;
3. Electrical safety: the electrical design and installation of self-built houses often do not meet professional standards, and there may be potential safety hazards such as electrical fire and electric shock;
4. Fire safety: the fire protection facilities of the self-built house may not be perfect, and once a fire occurs, it may lead to heavy losses;
5. Building quality: the building quality of the self-built house may also have problems, such as wall cracking, unstable foundation, etc., which may lead to the house tilting or collapse;
6. Environmental sanitation: There may be problems in the environmental sanitation of self-built houses, such as pipe blockage, garbage detention, etc., which may lead to the spread of diseases and environmental pollution.
