What is the difference between emergency ventilation and emergency smoke exhaust?

I’ve always been confused about these two things. What is the difference between emergency ventilation and emergency smoke exhaust? What are the different requirements in terms of design? Seeking guidance from those with more experience

There are differences between accident smoke extraction and accident ventilation in at least two aspects: one is the choice of materials, as accident smoke extraction requires consideration for high-temperature smoke, whereas accident ventilation deals more with normal temperature conditions； The second is the issue of emission point design; for emergency smoke exhaust, safety concerns such as smoke poisoning, suffocation, and burns from high temperatures must be taken into account, while emergency ventilation focuses more on the circulation of fresh air. For other aspects, please ask HVAC experts to provide additional information.
