Essential Items for A Home First Aid Kit
Gauze

You use gauze, which is typically made of a fabric designed to come away from the wound easily, to place directly over a wound and under outer dressing. Usually, medical gauze comes in squares of four inches diameter. For deep wounds, use a single piece. Do not use multiple pieces because there is the possibility of fibers coming away and getting lost in the wound. Change them out when the material becomes saturated if the injured person has not received medical treatment.
Tweezers And Scissors

Sterile tweezers and scissors play a vital role in first aid, as they help remove solid debris from a wound without using your fingers, which are likely riddled with harmful bacteria, and cut away material getting in the way of treatment. Place at least one pair of each in your first aid kit, particularly tweezers, to remove small objects like splinters, metal shards, or bee stingers. When using these tools, be gentle in your approach. If you act too vigorously or quickly, you could break a splinter. If you're trying to remove a stinger, squeezing it with tweezers could cause more venom to flow into the wound.
