Answer :
Final answer:
Firefighters should ensure proper ventilation to manage air effectively during search and rescue operations, by using entrainment devices. They shouldn't ignore air quality and neither use excessive force to open doors and windows.
Explanation:
To employ effective air management techniques during search and rescue operations, firefighters must primarily focus on ensuring proper ventilation. Proper ventilation reduces the amount of smoke and toxins within the structure, hence aiding in the visibility and survivability within. This involves functioning devices like a Bunsen burner, atomizer, common aspirator, or even a chimney, in their respective ways to manage the air flow. All these devices use the science of entrainment that uses increased fluid speed to create low pressures, which then entrain one fluid into another for efficient air management. Firefighters must ensure this air management in a efficient way, however, that doesn't mean that they should use excessive force to open doors and windows, as it might lead to unstable conditions and potential collapse of the structure. They should also never ignore air quality concerns, as this might put their own lives as well as the occupants at risk.
