What should be done after extinguishing a fire involving a window?

After extinguishing a fire involving a window, it is essential to open frames or casings to ensure that all potential hotspots are completely extinguished. Fire can easily hide in the voids of wall assemblies, attics, and other concealed spaces. If these areas are not checked thoroughly, there remains a risk of re-ignition, which can lead to further damage and endanger the safety of both firefighters and occupants. By carefully inspecting and opening the frames or casings, firefighters can confirm that there are no remaining embers or flames, ensuring that the fire is fully suppressed. This practice is a crucial part of the fire suppression process and demonstrates thoroughness and diligence in fire response efforts.

Other options, such as leaving the window untouched, sealing it for safety, or replacing it immediately, do not address the critical task of ensuring all fire activity is completely extinguished, and could result in dangerous situations if not properly managed.
