WebAug 6, 2024 · Most of the studies involving composite slabs under fire follow the standard fire scenario described by the ISO 834 curve, disregarding the cooling-phase. However, recent studies show that this phase is equally important, as it can lead to the collapse of the structure. Therefore, the present research carried out a parametric study, using … WebThe fire tetrahedron represents the addition of a component in the chemical chain reaction, to the three already present in the fire triangle.

WebThe classic “fire triangle” can be visualized as an and gate. For a fire to exist three conditions must be met: 1. Fuel above its flash point must be present. 2. Oxygen (usually as a component of air) must be present. 3. An ignition source such as an open flame or hot surface must exist. WebDue to this vaporization, oxygen will be displaced in the area of the fire, disrupting the Fire Tetrahedron. Small water droplets tend to remain suspended in the air and fill the entire space. The result being that any air the fire draws in becomes saturated with these droplets and vaporization occurs. Water mist also helps to pre-wet and
