A small flame can turn into a major fire very quickly, often in less than 30 seconds. The speed at which the fire grows depends on factors like the availability of fuel, oxygen, and heat. In situations with abundant flammable materials and good air circulation, a small flame can escalate rapidly, producing thick smoke and extreme heat. Within a few minutes, the fire can become fully developed and out of control, with temperatures reaching life- threatening levels and potentially causing structural damage. Key stages include the initial spread within 30 seconds, rapid growth by one to two minutes, and a critical flashover event that can occur around three minutes, where everything in a room ignites almost simultaneously, making escape nearly impossible without early detection and prompt action.
