What should be done to windows and doors during preparation for a fire emergency?

During preparation for a fire emergency, it's important to close and lock windows and doors to create a barrier against embers and flames. Closed windows and doors help to prevent drafts that could draw in smoke and embers, thereby protecting the interior of a structure from potential ignition. Keeping them locked also adds a layer of security, reducing the risk of unauthorized entry during an emergency situation. This action is a critical measure in ensuring that your home is better protected against the wildfires that can occur in the Wildland Urban Interface (WUI) areas.

Opening windows and doors, breaking them, or keeping them unlocked can increase the risk of fire entering the structure and significantly compromise safety. Thus, closing and securing these entrances is the most effective strategy in fire emergency preparation.
