During a flashover, temperatures in the smoke layer can spike to approximately how many degrees Celsius?

Explanation:
During a flashover, radiant heat from the burning fuel heats the smoke layer rapidly, causing a dramatic rise in temperature in that upper layer. That extreme heat can reach about 1200°C, which explains why fuels ignite almost simultaneously and why the conditions become deadly for anyone in the environment. Recognizing how hot the smoke layer gets reinforces the urgency of preventing flashover through heat management and careful ventilation.
