Also, regarding burn dressings, they are nice but generally unneeded for emergent situations.  Learn to assess degree of burns and cover them with a sterile dressing and you are fine.  Trust me when I tell you when they reach an ER they will remove the dressings and SCRUB the burns with brushes.  (yes, it hurts like H@ll!) but has to be done.  
As a former burn victim--2nd and 3rd: face, ears, and scalp--the brushing will give you a whole new reference point on a scale of 1 to 10...
