• Redressing of injuries and any amount of after treatment is outside the scope of first aid.
• Always remember the golden rule: "first do no harm" 
• If possible, a first aid provider should use Personal Protection Equipments (PPE) such as a personal mask, latex gloves, eye protection and apron/gown, if necessary.
