• Items held below the waist level are considered
  contaminated.
• Clean/gloved hands should be kept in front with the hands as close together as possible.
• Never turn your back on the aseptic field or leave the tray unattended.
• Use the field forceps to transfer ‘key parts’
  from the general aseptic field.
• Use the working forceps when working at the
  ‘key site’ (wound).
• Clean the wound from clean to dirty.
• Never retrace or go back.
