I was going over my supplies and kits, like tools and first aid items. THis got me to thinking. (Okay alert claxon is now off after going Battle Stations)
Consider dual purpose items, eg Female hygiene pads, unscented for the original and secondary use as improvised dressings.
Duct tape or the like with a few trshbags, makes a good improvised dressing for sucking chest wounds. Salt and sugar in maybe one ounce vials for emergency re hydration not just for flavoring. Additional 550 or para cord for lashing ot the tying of splints into position. Clean rags for cushioning, TP use or the like.
One thing that occured to me, The pool treatment chlorine tablets. IF you think about it, that will chorinate a large amunt of water so unless you are working on the 500 gallon level or better, remember that the concentration will be a hacke of a lot bigger than the typical water purifiation atabs.
Sewing kit, add heavier thread and canvas needles, No not for sutures, well okay maybe in a really bad situation, but clothing and equipment repair.
Quart and gallon sized zip locking bags. and more thantwo ways to make a fire. WHile it may sound odd a small shovel in the aid kit may be yuseful if you do not have hazmat containers for blody or blooded insturments a truiple bagged and wel buried place to dispose of said material my be sueful.
Just my 2 cents Oh and sorry for being away for so long.
