摘要

PROBLEM TO BE SOLVED: To further heighten spreading fire preventing effect and to positively protect an object by forming laminated structure of a surface side water absorptive polymeric material layer absorbing water spray and forming a water bearing layer, and a back side base material layer with fire resisting, heat resisting, heat insulating, waterproofing, resilient and protective functions. SOLUTION: This exposure preventive sheet 1 comprises a water absorptive polymeric material layer 2 that can at least absorb or contain spray water, and has flexibility deformable according to an object. When there is the possibility of spreading fire, the object is cut off from a fire by this exposure preventive sheet. A large quantity of water is absorbed by the water absorptive polymeric material layer 2 of the exposure preventive sheet 1, and a water bearing layer 2 is formed to prevent spreading fire.
