A

occurs between growth and fully developed phase, this is the point when fire has exhausted its fuel source and smoke has become so thick that it ignites when oxygen is introduced through ventilation. Causing temperatures to rise to 1000 to 1400 degrees. PPE does not protect against these temperatures.
