2 days ago · October 15, 2024. . Understanding fire science is crucial for investigations. The fire triangle is a traditional geometric model that represents the three components that are required for a fire to start. The fire tetrahedron builds on this model by introducing a fourth important element: the chemical chain reaction.
2 days ago · To create and sustain a fire, four components must be present: oxygen, heat, fuel, and a chemical reaction. The first three—oxygen, heat, and fuel—form what is known as the “fire triangle,” which is a fundamental concept in understanding how fires ignite and burn. When these three elements are present and interact, a chemical reaction ...
2 days ago · Water on the Earth’s surface moves in an unceasing cycle through rivers, oceans, clouds and rain called the water or hydrological cycle. The heat from the sun causes evaporation of water from oceans and from lakes and wetlands on land. Plants lose water through their leaves by transpiration.
6 days ago · the primary way that water extinguishes a fire is by absorbing heat which creates a cooling effect. when heated to its boiling point, water absorbs heat and converts into water vapor in a process called vaporization.
3 days ago · During the growth stage, the fire spreads rapidly, consuming any available fuel and expanding in size. Wildfires are especially dangerous during this phase since the fire can grow swiftly and uncontrollably. The wind tends to pick up and carry sparks and embers, spreading the fire further. Topography also plays a hand in this process, as ...
