Setting Temporary Fire Water Sources by Height Chongqing Introduces Hard Measures to Prevent Site Fires

On the afternoon of the 16th, the Chongqing Municipal Commission for Urban-Rural Development, the National Land and Housing Bureau, and the Fire Brigade jointly held an emergency meeting for safety production. The study introduced the “three prohibitions, four reinforcements, and five musts” work measures to prevent the tragedy in the construction site from recurring in our city.

Since the beginning of this year, there have been many fires in construction projects across the country, causing major economic losses and adverse social impacts. At present, there are many projects under construction in our city. The city renovating and building exterior facades are spread over a large area. The fire situation is very serious. According to the city fire brigade, this year the city has already had several major construction site fire accidents. For example, on October 31st, Jiangbei District Beicheng Art Building exterior decoration construction site was accidentally cited because of workers' use of welding tools. Combustibles, on-site fire protection guards leave the post and cause fire.

In response to the fire safety management at the construction site, today's emergency work will propose "three prohibitions, four reinforcements, and five musts" work measures. The meeting demanded that all districts and counties and relevant departments should take urgent actions to immediately organize special operations for the investigation and rectification of hidden fire hazards on the construction site of the project under construction. We must resolutely supervise and urge the rectification of hidden fire hazards discovered, and focus on establishing a fire safety responsibility system for construction units. Implement inspections on the use of fire, electricity, oil, gas and other management systems, check the conditions of fire escapes, fire water sources, fire-fighting facilities and equipment, and fire safety signs, and establish the “four capabilities” for fire safety on the construction site. The situation shall be included in the assessment content of the standardized inspection of safe and civilized construction on the construction site, and the standard of fire safety standardization in the construction site shall be effectively improved to prevent and reduce the occurrence of fire accidents on the construction site.

related information:

“Three prohibitions”: First, prohibiting burying, occupying, and occluding fire hydrants, and occupying the fire prevention distance; second, prohibiting occupation, blocking, closing evacuation passages, safety exits, and access to fire engines; third, prohibiting illegal fires, illegal smoking, and violations operating.

"Four enhancements": First, strengthen the allocation of fire-fighting equipment and facilities. The construction site should be equipped with necessary fire-fighting equipment so that it can be disposed of at any time. Inside the construction site, it is necessary to borrow indoor fire hydrants, lay fire hoses, and strengthen supervision. For large-scale personnel-intensive places under construction construction site or building construction height of more than 24 meters, the construction unit should be set to meet the construction schedule of temporary fire water sources, installation of fire hydrant and equipped with water hose;

The second is to strengthen the implementation of construction site management responsibilities. The construction unit must formulate and implement the fire safety system at the construction site, strengthen the management of the construction power line, eliminate combustibles on the construction surface in time, implement the fire safety protection measures, and formulate fire prevention and emergency evacuation plans. It is forbidden to set up staff quarters in uncompleted buildings;

The third is to strengthen the improvement of fire fighting knowledge and self-rescue escape skills. In view of the characteristics of frequent use of electricity at the construction site and high fire risk, the construction unit must combine the construction of fire safety “four capabilities” (check the ability to eliminate fire hazards, organize the ability to fight fires at the beginning, and organize the ability to evacuate and escape) Requirement for firefighting, education and training of firefighting, organization and development of employees' fire safety education and training and fire drills, strengthening employees' fire safety education and pre-post training, so that construction personnel can effectively achieve “one understands three meetings”, that is, to understand the fire risk of this place. Sex, alarm, fire extinguishment, escape, and improve self-prevention ability;

The fourth is to strengthen the implementation of fire protection regulations for building external wall insulation and decorative materials. In September last year, the Ministry of Public Security, the Ministry of Housing, and Urban-Rural Development jointly formulated the Provisional Regulations on Fire Protection of Exterior-insulated Civil Buildings and Exterior Wall Decoration for Civil Buildings, and proposed the fire protection design, construction, and use of exterior insulation systems and exterior wall decorations for civil buildings. The specific requirements clearly stipulate that the combustion performance of exterior insulation materials for civil buildings shall not be lower than Class B2. For residential buildings with a building height of 100 m or more and other civil buildings with a building height of 50 m or more, thermal insulation materials with class A combustion performance shall be used; In the construction of Class B1 or B2 insulation materials, horizontal fireproof insulation zones shall be provided in accordance with the prescribed layers. All construction projects in Nantong, Jiangsu and Urumqi, Xinjiang, and other places were using external insulation materials in violation of regulations. The design unit shall design the external wall insulation and decorative materials strictly in accordance with the regulations, and the plan review agency shall incorporate the burning performance of the external wall insulation and decorative materials into the key review content, and shall have clear concluding observations.

“Five musts”, that is, when performing open flame operations such as welding and gas welding, the internal fire approval procedures must be performed, the on-site and surrounding flammable materials must be removed, personnel must be assigned to perform on-site monitoring, and fire equipment must be deployed for on-site protection. Electrical welding operators are required to hold certificates.
