| 摘要 | PURPOSE: To secure safety for the works by covering furniture, ventilation device, etc., in a room sealedly before removing the ceiling made of inorganic synthetic fibers, and covering the obverse and reverse surfaces of the ceiling with vinyl derivative diluted with water. CONSTITUTION: The furniture, ventilation device, etc., in a room are covered with plastic sheet before removing the ceiling made of inorganic synthetic fibers which may contaminate human body and sealed with adhesive tapes. A vinyl derivative diluted with water is atomized by compressed air to the obverse and reverse surfaces of the ceiling so that elastic films are formed on the surfaces. Then the ceiling is removed and put in a sealed vessel to be transported to a waste deposit. The plastic sheets in the room are folded and cleaned by wet procedure, when care should be taken so that contaminant does not sputter. The nozzle 16 of a spear-form nozzle 10 is set between two crosspieces 22, and an envelope forming substance is atomized so that the whole surfaces of a mat 24 made of inorganic synthetic fiber are covered with film layers.
