I know I'm going to sound like a broken record (anyone else remember those?) but that's not a FAK in your Altoids tin, IMNSHO. <img src="images/graemlins/smile.gif" alt="" />

What is the purpose of your FAK? Is it to treat yourself, to treat friends and family, or to handle any accident you come across? I would certainly recommend at least one pair of protective gloves, preferably vinyl, some sterile gauze, and some tape. If you have to give CPR or mouth-to-mouth, you'll probably wish you had a pocket mask, although even the smallest of those likely won't fit in an Altoids tin. (I carry one on my keyring, tho.)

Personally, I don't carry sterile gauze pads or triangular bandages in my EDC, but if you're going to carry that much stuff anyway, a couple of 4" x 4" sterile gauze pads and a pair of vinyl surgical gloves isn't likely to overload you. <img src="images/graemlins/smile.gif" alt="" />
