Step 1: Bandage
You've wounded yourself. You tripped while hiking and skinned your knee or you cut your hand rock climbing. You need a bandage.
Determine the size of the wound to be covered. Make sure the wound is clean of dirt. If possible use antiseptic. Cut a length of gauze and fold it to the size of the wound. Then tear a piece of duct tape and place the gauze on the sticky side of the duct tape. Place the bandage on the wound with the gauze covering the wounded area.
Step 2: Splinter Remover
You have a splinter. You just had to walk barefoot through the soft green grass, and now have a sliver of wood embedded in your foot. Duct tape to the rescue.
Splinters can be difficult to remove. Especially if they are smaller. Tear a piece of duct tape large enough to cover the area where the splinter is located. Place the duct tape over the splinter, being sure to cover it on all sides. Press the duct tape firmly down. Lift the duct tape away. This should lift the splinter out also. Be sure to clean and bandage the wound.
