One of the most important tools for emergency preparedness is your Disaster Supplies Kit. Try to assemble your kit well in advance of an emergency. You may have to evacuate at a moments notice and take essentials with you. You may need to survive on your own after an emergency. This means having your own food, water and other supplies in sufficient quantity to last for at least 72 hours. First responders and relief workers will be on the scene after a disaster but they cannot reach everyone immediately. You could get help in hours or it might take days.
