Again hat's off to you Butch, what's truly mind blowing is the amount of people that would drive on by or turn around and go the other way. It's up to the few decent folk to set the standard for the rest to follow.
I came up on an Evil Kenievil impersonator back Nov and had to use my bag, here's a few things that I found useful:
6" or 8" ace bandage wraps, you can use them for pressure bandages
Isreali Field Dressing- this may be a toughy to find I got them from my unit's medic but if you find them GET EM!! They are an all inclosed hands free pressure dressing.
Heavy duty latex gloves, not the cheapy's you'll be working around broken glass
Good medic safety scissors, again not the cheapy's, the one's they advertize cutting through pennies.
3 words for you, Curlex,Curlex, Curlex- you can't have enough! I carry four 6" rolls on my flight gear in case of GSWs.
Duct tape or 100Mph tape- when hasn't this come in handy?
Small notebook and pen to take down info and pass to medics
Good flashlight-I use a Streamlight Stinger but Sure Fire or a Petzl Head lamp would be great too.
SAM's Splint- it's a rolled up piece of aluminum encased in foam that you can bend every which way to form a splint- I'll post an example pic when I get out of the sand box.
Bottled water and a wooby (poncho liner for you civi-minded folks) pic it up from the surplus store.
There are a few other ancilary items that I won't go into as they've been covered but there have been some great points brought up. Primarily, bring what you need to the fight but don't buy an SUV to accomodate your blow out bag. All the things I listed are in a Camelback Mule under the back seat of my truck. Also other things, Flares, Jumper Cables, Fire Extinguisher- my 2 bits on this if a fire does break out while you are still inside working on wounded then yeah attempt to put it out, but if the casualty is a safe distance away and upwind of the fire, let that bastard burn! You're primary consideration is the patient's [and your] safety.
Lastly on the matter of those clotting bandages a word of caution- and this may sound wierd but I watched this happen over here with one of our troops. Those bandages are impregnated with a derivative of shrimp shells- ain't mother nature great? - anyway if you're going to apply that bandage, prior to if able ask the victum if they are allergic to shellfish. DON'T LAUGH (I'm kinda chuckling about it myself) but seriously if they are and you stick that deal on them, you could possibly cause a hell of alot more complications. Our guy swole up so bad they almost had to crake him. So if it's a puncture wound I'd cram curlex into it and put a pressure bandage over it.
Sorry for the novel guys but a great topic.
