>>
>>
>>
>> · *Close and Secure Doors and Windows.** Closing windows and
>> doors is a simple step that can be easily forgotten while everyone is
>> securing objects, collecting their belongings, and heading indoors. Open
>> windows can result in water damage or broken glass. If there are shutters,
