Fires start when a flammable or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen, is exposed to a source of heat temperature above the flash point for the fuel mix, and is able to sustain a rate of rapid oxidation that produces a chain reaction.
Molelo o simolola fa selo se se thothetsang molelo, se kopane le selekanyo se se siameng sa gase ya oxygen kana sengwe se se na le oxygen, se le gaufi le motswedi wa mogote kana mogote o le kwa godimo ga flash point gore leokwane le ka kopangwa, gape gore e kgona go tshegetsa, selekanyo sa bonako jwa oxidation, e ntshang a tlhakatlhakanyo.
