Do anti downdraft cowls work?

How can backdraft be prevented?
Most of the time, this is accomplished by cutting an opening in the roof and refraining from opening any windows or doors on or below the fire floor until conditions have changed. This means that no search and rescue can occur and no water is being put on the fire until the vertical ventilation can be completed.
