In the usual sequence of fire growth, which term describes the phase following the initial stage?

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

Answer: (B)

Fire growth follows a progression from a small, developing fire to larger, more intense stages. After ignition, the next phase is growth, where heat feedback causes more fuels to ignite and flames to expand, increasing visibility and hazards. This stage bridges the incipient (initial) fire and the fully developed condition, which is when the space is most involved and heat release peaks. Decay comes later, as fuels are exhausted or ventilation changes reduce the fire’s intensity. So the phase that follows the initial stage is growth.
