An article about horizontal ventilation. It is the process of allowing heat and gases to travel in a lateral direction out of the structure.

An article about using a horizontal ventilation. Horizontal ventilation is the most effective means of ventilating dwellings when the fire does not involve an attic area and the structure does not have roof openings or easy access to such openings. It can work on any floor with windows in the fire area or adjacent area (i.e., high-rise multiple dwellings will need horizontal ventilation). You are still releasing the products of combustion into the atmosphere, improving interior conditions and thus giving the crews operating inside an opportunity to advance on the fire and to save possible occupants.
