If wounds are present protect yourself from infection by wearing latex gloves. If these are not available, use layers of gauze pads or a plastic garment. To figure out where the wound is, remove the clothes and check the area from which the blood is leaking.
Wounds should always be clean so as to prevent infection. If the bleeding is severe, leave the compression bandage on until the bleeding has stopped. To clean the wound, wash your hands well and wear gloves. Next, wash the wound. If the wound is superficial, wash the area around the wound with soap and water and do not use hydrogen peroxide. If a wound is at high risk of infection, such as an animal bite or a puncture wound, it is best to go to the emergency room. If the wound is cleaned at home remove foreign bodies, which have not gone away, with sterile tweezers.
Very large or heavily soiled wounds should be left to the appropriate personnel. After cleaning, cover the wound with a sterile dressing and keep it clean and dry. If the wound is superficial, antibiotic ointment can be applied. The dressing should be changed, or more often if it becomes damp and dirty.
