What is a common firefighting technique for ventilation?

Creating openings to release smoke and heat is an essential firefighting technique known as ventilation. This practice helps improve visibility and creates a safer environment for firefighters and potential victims inside the structure. When heat and smoke are allowed to exit the building, it reduces the chance of backdrafts and helps to manage the fire more effectively. Proper ventilation can facilitate a more efficient attack on the fire and can significantly improve conditions for rescue operations.

In contrast, using chemicals to suppress flames is a different approach focused primarily on extinguishing the fire rather than managing smoke and heat. Blocking windows would exacerbate a fire situation by trapping heat and smoke inside, leading to increased danger. Increasing water pressure does not directly relate to ventilation techniques; instead, it pertains to the effectiveness of water delivery or flow rate during firefighting operations.
