syttymiskriteerit
Syttymiskriteerit refers to the conditions or criteria that must be met for a fire to ignite and sustain itself. Understanding these criteria is fundamental in fire safety, fire investigation, and the study of combustion. There are typically three essential elements required for a fire: fuel, oxygen, and an ignition source. These are often depicted as the "fire triangle."
Fuel is any material that can burn. This can range from solid materials like wood and paper
Oxygen, typically from the air, acts as the oxidizer in the combustion process. While air contains approximately
An ignition source is the energy required to raise the fuel to its ignition temperature. This can
In some contexts, a fourth element, the "chemical chain reaction," is added to form the "fire tetrahedron."
