Those four things are: the need for shelter to be safe from the elements, first aid, food and water and the ability to protect yourself from people or animals that would attempt to harm you. Long-term supplies to set aside for safety from the elements should be tents for each member of the family if you’re going to use single man tents, sleeping bags, thermal blankets and ponchos. Safety from the elements also includes the ability to keep warm if necessary. You’ll need an axe for cutting wood for fires, a way to start a fire – such as waterproof matches or a lighter, gloves and a multi tool. For first aid survival, you’ll need a first aid kit that includes insect repellent, personal hygiene items and field dressings. You’ll need tweezers, scissors and a surgical kit. You may not know how to close a large wound, but in case you have to save a life, you should know this information. You can keep a how-to guide on hand with your supplies. Make sure you have supplies that will treat teeth or eye problems too.
