High rise buildings have a certain degree of enclosure, with complex internal structures and dense personnel. The higher the height, the greater the difficulty of escape and evacuation in the event of a fire. Therefore, it is necessary to attach great importance to the systematization and standardization of building fire prevention, especially for super high rise buildings.
Data shows that in the first three quarters of 2021, the Fire Rescue Bureau reported 2808 high-rise building fires and 107 deaths nationwide. They account for 9.2% and 6.8% of the total number of building fires, respectively, an increase of 4% and 1.1% compared to the same period in 2020.
So, how can we reduce the hazards of high-rise building fires?
1: Using A-grade non combustible insulation materials
Article 6.7 of GB 50016-2014 "Code for Fire Protection Design of Buildings" has clear provisions for building insulation and exterior wall decoration. The internal and external insulation systems of buildings should use insulation materials with combustion performance of Class A, and B2 insulation materials should not be used. B3 insulation materials are strictly prohibited.
Rock wool is an A-grade non combustible insulation material that does not shrink, deform, produce droplets, or toxic smoke in the event of a fire. It is the first safety bolt for high-rise buildings to slow down the rapid spread of fires and buy valuable time for rescue efforts. Rock wool can be applied to different parts and structures of buildings, making them both energy-efficient and safe.
2: Setting up building fire protection facilities
Building fire-fighting facilities commonly used include automatic fire alarm system, automatic sprinkler system, fire hydrant system, gas extinguishing system, foam extinguishing system, dry powder extinguishing system, smoke control and smoke exhaust system, safety evacuation system, etc.
Let's focus on the smoke exhaust system:
In fire accidents, smoke is the main factor causing casualties in building fires. The smoke carries toxic gases and microparticles with high temperatures, posing a great threat to human life. The purpose of smoke exhaust systems is to timely eliminate a large amount of smoke generated by fires, prevent smoke from spreading outside the smoke prevention zone, ensure the smooth evacuation and safe refuge of personnel inside buildings, and create favorable conditions for fire rescue. Smoke prevention and exhaust in buildings are necessary conditions to ensure the safe evacuation of personnel inside the building.
