Listed renovation!It's about the safety of Yueyang's self -built house

The reporter learned from the Office of the Leading Group of the Special Rectification of Housing Safety in Yueyang City that the city will be listed to rectify the safety of operating residents' self -built houses.

1. Scope and time limit for rectification

For the three floors of dense places such as urban and rural areas, urban villages, school hospitals, industrial parks, resettlement areas, collective towns, scenic spots, commercial districts and other dense places, more than 10 rental operations involved in 10 people Business residents have been established for listing. The listing work must be completed by June 30.

2. Types and standards for rectification

(1) Type

According to the classification of hidden dangers of self -built housing, the three -color logo listing system of "red, yellow, and blue" is implemented. The red card is prohibited from using the logo; the yellow card is suspended for use; Red card warnings, yellow card warnings, and blue card warning houses correspond to the hidden housing, major safety hazard houses, and general safety hazards houses, respectively; houses that have not found hidden safety hazards are not listed.

(2) Standard

Third, rectification procedures and measures

(1) Program

During the investigation, the environment and basic situation of the house venue must be investigated and analyzed, and on -site investigation records and preliminary judgments must be made. House safety special rectification worker

The Office of the Leading Group is posted on the obvious position of the house (red, yellow, and blue card) in the obvious position of the house.

(2) Disposal measures

1. Property owners and operators (users) shall take corresponding measures to eliminate hidden dangers in time according to the results of hidden dangers of house safety.

2. If the foundation of the foundation is lost, the main structure is severely damaged, the use of flammable, combustible clamping core color steel plates, etc., and other particularly major safety hazards (red card warnings), after identification and confirmation Measures; local damage to the main structure, failure to separate fire separation in accordance with regulations, evacuation channels and safety exports, and fail to set up major safety hazards (yellow card warnings) such as fire protection facilities and equipment in accordance with regulations. Engineering measures such as fire separation and evacuation channels, and setting fire facilities; general safety hazards (blue card warnings) such as minor damage and daily fire safety management measures, shall be taken to take repair and reinforcement, strengthen management measures, etc., and resolutely prevent prevention Major house collapse and fire accidents. The classification and disposal work shall implement on -site logos, monocularization and account sales number management.

3. The operating self -built house for the listing warning, the county and urban people's government (management committee) shall urge the property owner and operator (user) to conduct a house safety appraisal in a timely manner, and deal with it in accordance with the safety appraisal report. Essence

4. For business self -built houses with hidden safety hazards, the property owner and operator (user) shall not be operated before the safety hazard cannot be eliminated.5. The rectification work should be implemented one by one, clarify the period of rectification and rectification measures, and achieve one rectification, sell one item, and ensure that the safety hazards of the hidden safety hazards detected by the house are fully covered.For those with major safety hazards, it is necessary to implement listing supervision and rectification within a time limit.After the rectification of the hidden dangers of the self -built housing of the alarm sign, it can be "delisted" after confirming the county and city people's government (management committee) to form a closed loop management.
