What is the first stage of a fire called?

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

Answer: (A)

The first stage is the incipient stage, when a fire has just begun. Heat release is low and confined to the area of origin; flames may be small and smoke light. This moment is the most controllable for early suppression and evacuation because the fire hasn’t yet grown or spread. If it isn’t addressed, it can quickly progress to the growth stage, where the fire intensifies and expands, then to fully developed, and finally to decay as fuels are consumed. Understanding this progression helps firefighters act quickly to prevent a larger, more dangerous situation.
