Description

{SHEET FOR PREVENTING SCATTERING FOR ASBESTOS WORK}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anti-scattering sheet for asbestos working, and more particularly, to an anti-scattering sheet for asbestos working, which can easily perform an operation when dismantling and removing an asbestos-containing material such as a ceiling material, , And to reduce the cost by omitting unnecessary work processes and to perform a more rapid and efficient asbestos dismantling work.

Various buildings such as buildings, shopping malls, and houses are usually installed with various interior and exterior materials using asbestos or asbestos-containing materials. Asbestos is a material that forms a fiber-like aggregate that has a high tensile strength and flexibility and has a silk-like characteristic luster among minerals produced from natural stone. The single fiber is very thin and easily fibrillated by fine fiber bundles, It is easy to float in the atmosphere.

In addition, asbestos is generally divided into two types in terms of minerals composition. One of them is chrysotile-based asbestos, which is called as 温 石 綿, The other is amphibole (amorphous) asbestos, which is weak in fibers, but has strong properties in chemicals. Of course, these creosote and amphibole asbestos are produced in the form of veins in serpentinite.

Such asbestos is cheap, has excellent bonding strength with other materials, has excellent mechanical strength, and is excellent in nonflammability, insulation, durability, insulation, and warmth, and can be used for all general building materials such as building materials such as mill boards, asbestos slats, There are a wide range of applications such as fire, refractory, insulation, insulation, electrical insulating material, electrolytic membrane material, and brake lining material.

However, since asbestos is thin and sharp in its fiber form, it is very stiff and especially has a high preservation ability in the body. Therefore, it is known that asbestos is inhaled for a long period of time to cause occupational diseases such as lung cancer, malignant mesothelioma and asbestosis. It is strictly regulated about the processing.

Although asbestos has been designated as toxic designated waste in recent years, asbestos removal has been frequently carried out in the subway sector, schools, and infrastructure facilities that are used by the public. In the case of asbestos, the construction waste should be strictly classified as general construction waste and landfill separately. However, since most of the construction sites are accompanied by disasters such as general buildings, the second pollution is caused. It is becoming a deadly threat to health.

In particular, among these kinds of asbestos, Crocidolite is the most dangerous, followed by Amosite and then Chrysotile. Asbestos is a very fine fiber, and the thickness of a single fiber is 3 / 100,000ths of a millimeter, which is less than 1 / 5,000th of its hair, so it can not be seen. And aspiration of only one strand of asbestos has been found to be fatal to the human body.

Therefore, among workers who handle asbestos, there are many cases where they are caught by asbestos, died from lung cancer or malignant mesothelioma, and various problems are caused thereby.

In addition, since the majority of asbestos is contained in the ceiling material of the subway sector, schools, hospitals, and infrastructure facilities used by the public, the amount of indoor asbestos floats reaches dozens of times the specified value, and the processing of the ceiling- .

Due to the risk of asbestos, it is desirable to remove the entire tex immediately in the case of a building using asbestos as a ceiling material, but the cost is astronomical and takes a long time and inconvenience , Construction work is mainly focused on the partial dismantling work from the place where the system air conditioner installation or fluorescent lamp replacement is needed first.

The existing asbestos dismantling work is a vinyl sheet, which isolates the construction compartment from the outside of a certain space, installs the changing room, bath room, and work clothes changing room at the entrance of the exterior and the construction compartment, and installs the anti- And asbestos dismantling work is carried out. At this time, when the work space is surrounded by the vinyl sheet, it is possible to form a certain space by using a support stand or the like. The work space should be kept at a negative pressure during the work. If it goes out of the workplace after the dismantling work, it is necessary to remove the work clothes after bathing in the bath room, collect all the vinyl sheets etc. Should be treated. In the case of inserting the construction section from the outside with the vinyl sheet, the operator has to enter the construction section, thereby requiring a changing room, a bath room and a work clothes changing room, which requires a lot of time and cost.

On the other hand, if the asbestos is scattered, the building can be opened immediately after the building is closed and closed, and the worker can open the building after performing the asbestos removal work, so that the building is closed while the removal of the asbestos is completed There is a problem that it must be done. Therefore, there is an inconvenience that the study and work in all the indoor buildings including the school or the government offices are interrupted to remove the scattered asbestos.
