Individuals are responsible for their own safety and the safety of their families. You should be prepared for an minimum of 72 hours. Supplies may not be available to purchase in an emergency situation, so it is important to have provisions in an emergency kit safely stored in your home. These supplies should be refreshed at a minimum frequency of once per year. It is a good idea to update your supplies when you check the batteries in your smoke detector (every six months).
Local community government and emergency services are the first to respond to an emergency. Non-governmental organizations like the Canadian Red Cross and Salvation Army also assist at this level of an emergency. It may take emergency workers some time to reach you as they help those in desperate need.
