Abstract
Wet water has been known as having an effective extinguishing action for the fires of solid fuels, but it has scarcely been used. It is because the effects of wet water is not appreciated precisely.
For this reason, small scale extinction tests of tire and wood crib fires using wet water and plain water are conducted, and the total amount of water required for a complete fire extinction, the useless water drained off, the effective water soaked into a burning solid and the other items were measured in detail.
Thus, it was found from the results that the difference of fire suppression effect between plain and wet water is not so large for wood fire, although striking for tire fire, and that the effect of wet water is its durability in comparison with plain water, because of its large soaking ability.
