List the four phases of fire growth
WebAccording to biologists, fire is not alive. Fire does share many similarities with living things, in that it needs oxygen and fuel, and it grows, moves, and spreads. However, it does not fit all the biological criteria of life. I’ve been digging into the life cycle of fire to see just how deep these similarities go. WebFire Growth. After a fire has ignited and steady burning is established, the fire enters a stage of growth. Figure 6: Fire growth. In Figure 6, the fire has ignited behind the couch, possibly due to an electrical outlet or extension cord. The fire has established itself and is now growing up the wall, fuelled by the fabric and foam in the couch.

Webthe heat release rate (HRR) is described with an exponential fire growth rate for the pre-flashover phase [1]. This in turn forms the basis of the design. The exponential fire growth rate is often referred to as the alpha-t2 fire curve, and it is described in textbooks and guidelines used for fire safety engineering, see Eq. 1. Q t2 (1)
