Fireproof covers

Relocation of combustibles—Where practicable, all combustibles must be relocated at least 35 feet from the work site. Where relocation is impracticable, combustibles must be protected with fireproofed covers, or otherwise shielded with metal of fire-resistant guards or curtains. 

Fireproof covering materials in Japan before 1955 or so, were likely to be of sprayed asbestos form. However, as the buildings have become taUer and larger, various fireproof covering materials began to be used, including sprayed, adhesive, tape and coating types. 

Properties of fireproof covering materials include small thermal conductivity, abundant thermal absorption capability, and long-term durability. The materials that once dominated fireproof covering materials, sprayed asbestos, is a mixed material made of asbestos with Portland cement as the bonding agent. Asbestos is excellent for dispersion, fire resistance, and alkali resistance. It is a fibrous material with crystalline water that provides excellent thermal resistance and heat absorption. Unfortunately, because there is legitimate concern about the health problems caused by asbestos, other inorganic materials as shown in Table 2 are currently used.
