The four stages of fire development:
1. Initial stage: within ten minutes after the fire started, the burning area was not large, the flue gas flow rate was slow, the energy radiated by the flame was not much, the surrounding objects and structures began to heat up, and the temperature did not rise fast. The initial stage is the most favorable time to put out the fire, and it is also the most favorable time for the safe evacuation of personnel. Therefore, we should try to control and eliminate the fire in time at the initial stage.
2. Development stage: the burning area expands and the burning speed increases.
3. Violent stage: the burning intensity is the strongest, and the heat radiation is the strongest.
4. Descent and extinction stage: gradually weaken until extinction.
