Water. Drinking water, water purification system (or tablets), and a water bottle or canteen. Food. Anything that is long lasting, lightweight, and nutritious such as protein bars, dehydrated meals, MREs24, certain canned goods, rice, and beans. Clothing. Assure it’s appropriate to a wide range of temperatures and environments, including gloves, raingear, and multiple layers that can be taken on or off as needed. Shelter. This may include a tarp or tent, sleeping bag or survival blanket, and ground pad or yoga mat. A camper or trailer is a fantastic, portable shelter, with many of the comforts of home. If you own one keep it stocked with supplies to facilitate leaving in a hurry, as it can take several hours load up and move out if you’re not ready. In certain circumstances that might mean having to leave it behind. Heat source. Lighter or other reliable ignition source (e.g., magnesium striker), tinder, and waterproof storage. Include a rocket stove or biomass burner if possible, they’re inexpensive, take very little fuel, and incredibly useful in an emergency. Self-defense/hunting gear. Firearm(s) and ammunition, fishing gear, multi-tool/knife, maps, and compass, and GPS (it’s not a good idea to rely solely on a GPS as you may find yourself operating without a battery or charger). First aid. First aid kit, first aid book, insect repellant, suntan lotion, and any needed medicines you have been prescribed. If possible add potassium iodide (for radiation emergencies) and antibiotics (for bio attacks) to your kit. Hygiene. Hand soap, sanitizer, toilet paper, towel, toothbrush, toothpaste, dental floss, and garbage bags. Tools. Hatchet (preferably) or machete, can opener, cooking tools (e.g., portable stove, pot, frying pan, utensils, and fuel), rope, duct tape, sunglasses, rubber tubing, and sewing kit. Lighting and communications. LED headlamp, glow sticks, candles, cell phone, charger (preferably hand crank or solar), emergency radio (preferably with hand crank that covers AM, FM, and Marine frequencies) and extra batteries, writing implements, and paper. Cash or barter. You never know how long an emergency will last. Extensive power outages mean no cash machines, so keep a few hundred dollars in small bills, gold or silver coins, or other valuables on hand.
