A first-aid kit is an essential item to have in any home or workplace. It contains items that can be used to treat minor injuries, such as GAUZE, bandages, iodine, and TAPE. GAUZE is a thin, open-weave fabric used to cover wounds and absorb blood. Bandages are strips of cloth or plastic used to secure GAUZE or other dressings to a wound. Iodine is an antiseptic used to clean and disinfect wounds. TAPE is used to hold dressings in place. All of these items are important components of a first-aid kit.
