Fire hazard of color steel building

Color steel plate with light, high strength, easy installation and so on, is currently widely used in earthquake and other disaster areas to resettlement board room, plant, warehouse, shop, kiosk and construction site temporary housing, especially some high-rise buildings and Large-span construction, the application of this light steel structure building advantage is more obvious. But in recent years, the color of the steel room caused by fire and because of iron fence, billboards block the impact of personnel to escape and fire fighting rescue occurred, resulting in heavy casualties and property damage. According to preliminary statistics, since 2010, the national color steel temporary building fire 897, a total of 102 people were killed, 55 people were injured, direct economic losses of more than 100 million yuan. Over the past three years, the country occurred in 263 from the death of the larger fire, due to the construction of external walls and windows set iron fence, billboards and other obstacles affect the escape of 29 people, a total of 134 people were killed and 68 injured. How to prevent and control color steel building fire, become a social concern.
Characteristics of Fire in Color Steel Building
(A) the rapid development of fire, spread quickly. Due to the large span of steel structure space, combustible materials, in the event of fire, the rapid development of fire, burning violent, easy to form a large area of ​​fire.
(B) burning a large number of strong black smoke and gas, resulting in the fire scene of the firefighters affected, not easy to observe the fire point, and can not carry out search and rescue personnel, so that internal staff evacuation difficulties, easily lead to casualties.
(C) building fire resistance level is low, prone to the top, local, wall, floor collapse, hinder fire fighting, easily lead to casualties.
(D) the fire point concealment, fighting difficulties, clean up a long time to clean fire
(5) The construction of fire facilities is incomplete and the water supply is lacking. Color steel building mostly urban and rural areas and temporary construction, fire facilities can not keep up, resulting in fire site water supply difficulties.
