Why is fire resistance necessary?@-For safe livelihood-

If a house catches fire
When a fire occurs in a house, the temperature in the room usually reaches 500 C in about 5 to 10 minutes.
Furthermore, when a phenomenon called flashover occurs, indoor temperature will reach 1000 C in a matter of seconds.
Flashover
A phenomenon in which a fire occurs in a room and generating flammable gas, and then the flame spreads in an instant after the gas is ignited by the flame.
We must use materials that will not burn or burn easily to resist the delay of flashover phenomena and resistance to temperature rise, particularly in places where fire is used (such as kitchen and bathroom water heater). According to the Building Standards Law, this material is called fire protection material and this law stipulates places that should be applied with a finish made from fire protection material. Such restrictions are called interior restrictions. By implementing these restrictions, evacuation route can be secured.
Reasons why fire resistance is necessary
After flashover, fire will continue to burn at 1000 C and will try to spread. In order to prevent the spread of fire in this building and to prevent the building from collapsing due to flames, it is necessary to use fire resistant walls and encase the pillars etc with fire resistant materials.
When receiving heat due to ordinary fire...
Fire resistance
  • Damage resistance:
    Performance that does not cause deformation, melting, destruction or other damage
  • Flame retardancy:
    Prevents occurrence of cracks or other damage that will cause the fire to spread from the indoor side to the outdoors
  • Heat insulation:
    Performance to prevent the temperature on the non-heated side rising above the ignition temperature of combustible matter
*Ignition temperature of combustible matter: 200 C at the highest temperature part, 160 C on average

Fire resistance in Tiger Board
"Tiger Board" stops flames so that fire in one room does not spread to the next room. The mechanism is unique, in which when the board is exposed to fire, it releases water from the inside of the board, suppressing the temperature rise through the evaporation effect, thus exhibiting fire resistance.
What is fire prevention?
The meaning of fire resistance is to secure the safety of human beings in the building through "the durability of the site of the building" and furthermore to "prevent the spread of fire inside the building". On the other hand, fire protection means "ability to prevent the fire that comes from the burning house next door moving into the building." In other words, it is the ability to prevent the spread of fire between buildings.
