Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a treatment technique for preventing scattering of inorganic fibers, which is useful for a wet sprayed refractory covering material that is rigid and less permeable to liquid or a molded plate refractory covering material that is rigid and less permeable to liquid to reliably keep inorganic fibers (particularly, asbestos) contained in the refractory covering material.SOLUTION: In the treatment method for preventing scattering of inorganic fibers in which a penetrant 30 is impregnated into a surface of a refractory covering material 10 containing inorganic fibers, the impregnated penetrant 30 is solidified, and the surface is further coated with a flame retardant coating material 40 to prevent scattering of the inorganic fibers from the refractory covering material 10, an excess of the penetrant 30 not penetrating into the refractory covering material 10 that is a wet sprayed refractory covering material remains on the surface of the refractory covering material 10 and covers the surface in such a way as to cover granules 20 sticking to the surface of the refractory covering material 10, so that the penetrant 30 and the flame retardant coating material 40 come in surface contact with each other.
