One is the hidden danger of foam color steel plate.
1. High temperature and smoke accumulation make it difficult to put out the fire. The construction of color steel plate structure is relatively closed. When polymer sandwich materials such
as polyurethane foam and polystyrene foam are burned, a lot of high temperature and dense smoke will be generated, which will make buildings smoke in a short time and accumulate a lot of heat, which will bring great difficulties to fire fighting.
2. Poor fire resistance, easy to form large-area collapse. Color steel is a non combustible material at room temperature, but its strength will decrease rapidly after flame baking. Especially in case of fire in long-span buildings, color steel components
are easy to deform due to high temperature, resulting in large-scale collapse of buildings.
3. The construction enterprise is large in scale and easy to form three-dimensional combustion fire. Caigang construction company has developed on a large
scale in the construction market because of its high work intensity, light weight and convenient construction. In case of fire, a large amount of flue gas heat diffuses upward through various pipes and channels, which is easy to form a three-dimensional
4. It is easy to cause casualties. In case of fire, toxic and harmful gases or impurities gradually increase in the flammable polymer materials filled with foam in color steel sheets, which makes people more and more threatened.
5. The wires and cables used in the color steel plate house are mostly fake and inferior products, which are easy to aging. As wires and cables are buried in the interlayer, aging wires and cables are easy to ignite the core material in the interlayer.
2. Fire prevention measures
1. In the process of use and management, some main heat sources and fire sources should not be close to the color steel plate, and keep a certain distance from the enterprise.
2. If you want to decorate the kitchen
in the color steel room, you need heat insulation.
3. Wires and cables shall not pass through color steel plate. If it is necessary to pass through protective sleeves, sockets and switch boxes, metal galvanized boxes and transparent packaging shall
4. Simple fire-fighting equipment shall be equipped indoors and outdoors, and fire alarm shall be installed when conditions permit, so as to facilitate rapid evacuation of personnel.
5. According to the requirements of the Fire Department
of the Ministry of public security, color steel plates below grade A shall not be built in densely populated places such as nurseries, kindergartens, nursing homes, welfare homes, boarding schools and hospitals; Densely populated places built with color
steel plates, which are lower than class a requirements, shall not pass the fire design review, acceptance or sampling inspection; All public gathering places constructed of color steel plates lower than class a requirements shall not pass the fire safety
inspection before use and operation; For densely populated places built with color steel plates found in the inspection, all places lower than class a requirements shall be temporarily closed, and the use shall be ordered to change. Items that cannot
be changed must be deleted.
