BZK is a common way of saying benzalkonium. In the US, a box of 100 wipes costs about $5 from Amazon.

Thanks , I have some of these in my FAKs. Just didn't know what each was used for

Last few days I had a knee problem (again) and had to empty a FAK box to use for medical care kit and took a few items from each box to assemble this one ( scissors , tape , gauze , ..etc. ) plus a tool box ( don't laugh please ) for the bulkier items like muscle ointment and fish oil capsule box ..etc.

So, while I was playing with the contents I saw some interesting stuff like BZK wipes and few others

Thanks again.

Oh, and if there is a good pdf file on first aid material , I will really appreciate. Most pdf stuff I have seen so far was ads for selling FAKs.

Perhaps the best free resource I've found for first aid information and material comes from Where There Is No Doctor, which you can download from http://hesperian.org/books-and-resources/#.

What is the difference between it and betadine?

I'm not an expert. Betadine (aka povidone-iodine) leaves a reddish residue. I've read that the residue provides some lingering antiseptic value. I've also read that it's not flammable, which would explain why they like it so much in operating rooms. Finally, I've read that it isn't appropriate for long-term wound care as it may inhibit clotting. You can also use it to disinfect water.

BZK doesn't leave a residue, which might be better or worse for you. It's at least somewhat flammable, and I wouldn't try to use it to disinfect water.

I'm European and we primarily use Chlorhexidine or Betadine. This what i was taught:

Chlorhexidine stings, but is clear and does not cause issues with people sensitive to iodine.

Betadine doesn't sting, but stains. So we are taught not to use betadine when you need to go a doctor to get the wound looked at. The staining makes it harder to identify what is what.

Is there an easy way to EDC exam gloves? Hard case preferred as they don't get used for a year or more

I put a set in a zip-lock bag along with an N95. Stored the zip-lock in an inside pocket of my EDC backpack. There are identical zip-lock bags in each of my FAK's -- first thing you see when you open the kit.

I put mine in a small ziploc baggie. Several of these are doing just fine after two or more years.

I buy really good (NAR Black Talon, no affiliation) exam gloves, and they last a long time in my FAKs.
