Which term describes the stage immediately following the initial incipient stage?

• A. Incipient
• B. Growth
• C. Fully developed
• D. Decay

Answer: (B)

Understanding how a fire progresses helps explain this answer. After ignition, the incipient stage is the very early phase where the fire is just starting and still localized. As the fire gains energy and begins to spread to additional fuels, it enters the growth stage. This is the period when flames become more visible, heat release increases, and the fire expands beyond its origin. It sits between the initial incipient phase and the peak, fully developed phase, and before decay as fuels are consumed or conditions limit the fire. So the term that describes the stage immediately following the initial incipient stage is growth.
