How to treat a skin flap or abrasion during first aid
Wash your hands.
Before you take action to address an abrasion or a skin flap, you need to ensure that you are lowering any potential risk of infection. The abrasion itself is unlikely to be serious, but if it becomes infected you could become very ill.
Thoroughly wash your hands with soap and water, before you turn your attention to the wound. If you have access sterile latex gloves you can wear these as well.
