A fire broke out in a medical center in Hengyang, Hunan Province, killing five people. What was the cause of the accident?

A major fire broke out in a medical care center in Shigu District, Hengyang City, Hunan Province. After learning the information, the fire department and local related personnel immediately rushed to the scene, dispatched forces in time, and mobilized all forces to put out the fire and rescue the injured. The fire has been put out. During the fire, there were 19 people in the old-age care center, and 5 people were safely transferred through rapid transfer. 14 people were sent to the hospital by fire, among them, 5 people died after intensive treatment, and other injured people are still trying their best to rescue them. The cause of the incident is under active and intense investigation. According to the survey results, the fire was caused by electricity, and this medical center can be said to be an illegal building. The building of this care center is very old, and there are already potential safety hazards, especially in the circuit and construction, but the problem has not been solved. The nursing center is on the second floor of the hospital building. I don't know when temporary buildings were added to the roof, and these buildings all look simple, especially in terms of circuits and safe escape. Moreover, the fire resistance of building materials is not high, which can not meet the conditions and requirements of old-age care. It happened because of electricity leakage, and eventually caused a fire because of aging lines and housing materials. The old-age care center has no fire extinguishing device, fire alarm system and circuit, which is particularly perfunctory. It is set in various unsafe areas, without evacuation passages and exits, and without emergency plans and drills. Moreover, the pension center here is also an illegal building. For such buildings, there is no forced demolition. Relevant personnel of relevant departments have been placed on file for investigation, and compulsory measures have been taken against the legal spokesperson of this pension center. Moreover, it is understood that many people have complained to relevant departments about such illegal buildings, which have not been resolved.
