You probably know how to use every item in your survival kit, but what if you are injured in an emergency?
Would family members know how much tincture of iodine to add to a quart of water to purify it? Would a friend know to scrape shavings from the magnesium block to start a fire? Being dehydrated, very cold or simply in a very stressful situation will make the human brain foggy. Anyone can become confused.
Some survival experts like Cody Lundin recommend putting bright duct tape on pieces in your survival kit. More visibility means less chance of getting lost or left behind when you move on. This habit also provides a place to write simple instructions using a permanent marker. Figure out the shortest way to write instructions anyone can understand and critical items in your emergency kit are instantly improved.
