I also agree with scafool. I have been certified in First Aid, my training can be summed up as this, "I am not a doctor, but I can help you get help." immobilization and not causing further harm are the two big ideas that I took away from it. Just because I have a needle and thread, or superglue, does not mean I should attempt to sew/glue someone else together, and i would be LIABLE if i did. Good samaritian laws protect people giving first aid but they do not cover "I saw this on ER last night...." or "I have read about this in an old army manual so I must be a medic" type stuff. First aid is about keeping a person alive, intact, and not getting further hurt. Its not about being a superman. I am qualified for rescue breathing, not intubating. I can splint a broken bone, not set and cast it. (only if there is a need. If the paramedics are in route I wait and monitor) My number one priority is to get help.

I agree with the OP pretty well, I figured out with my last busted knuckle at work that 4 iodine wipes are just about useless. (I was changing the oil on a car so i had oil and grease on my hands it sure did make opening the foil package fun too!) simple soap and water is a much better choice. I mean simple soap, we also have the soap that has grit in it which is a really bad idea to clean a wound with.

for minor scrapes and cuts usually I make sure the cut site gets flushed by blood, then bandage with a little triple A. No washing or alcohol or iodine. the bandaid sticks, I dont kill extra cells, the triple A keeps the cut clean and non-sticking. I understand many will not approve, but think back to when you were a kid.
