What is the method of ventilation that uses blowers, exhaust fans, and smoke ejectors called?

The method of ventilation that utilizes blowers, exhaust fans, and smoke ejectors is identified as mechanical ventilation. This approach employs powered equipment to facilitate the movement of air, specifically to remove smoke and heat from a structure during a fire incident. By using mechanical devices, firefighters can significantly enhance the efficiency and control of airflow, which is crucial for creating safe conditions for both occupants and responders.

Mechanical ventilation is particularly effective in situations where natural airflow may not be sufficient due to building design or external environmental conditions. It allows for a more rapid and directed removal of harmful gases and smoke, thereby improving visibility and reducing the risk of fire spread. Additionally, by managing how air enters and exits a space, this method can help in controlling the fire environment, making it safer for operations and evacuation.
