What type of ventilation is typically used for a structure fire?

The use of both horizontal and vertical ventilation in structure fire scenarios is essential for effective firefighting operations. Horizontal ventilation involves opening windows or doors on the same level as the fire to allow smoke and heat to escape while also allowing fresh air to enter. This helps improve visibility for firefighters and reduces the risk of flashover by managing the thermal layer within the structure.

Vertical ventilation is performed by creating openings in the roof or upper levels of the building, which allows heat and smoke to rise and exit. This can significantly reduce the temperature within the structure, improving conditions for both firefighters and any individuals who may be trapped inside. Together, these methods help to control the fire environment, enhance firefighter safety, and increase the likelihood of successful fire suppression.

Using both types of ventilation effectively complements each other and addresses different aspects of smoke and heat removal, making it the most comprehensive approach in structure firefighting.
