First aid kits (FAKs) need to be regularly checked, refreshed, and updated. Here’s a wee tip:
If you are making up a new FAK or refreshing an old one you may find costs have risen to uncomfortable levels for some things that need replacing or refreshing. Use alternate materials. Sterile pads for wounds? Get a double whammy by using. . . ladies’ panty liners. no, seriously! Most even contain hydrophilic homopolymers or copolymers that help contain blood lost. Oh, and duct tape is sometimes appropriate as a substitute for medical adhesive tapes. Sometimes.
And about that bleeding. . . clotting agents. Quickclot, Woundseal, et al, can be a wee tad pricey for what is essentially a finely-ground clay (kaolin), but if you reach into your kitchen cabinet (or wherever you keep your spices and such) and pull out some alum, you’ll have something that works nearly as well. There are LOADS of workable first aid materials available in nearly every household. The key is identifying them by function and getting one’s head around using them properly for first aid. (Then, of course, one has to make sure they are included in one’s kits. 😉 )
One thing I do not recommend replying on ad hoc substitutions for effective results is “field expedient” tourniquets as first line equipment for stopping large bleeds. Nope. Shell out for a good CAT (Combat Application Tourniquet) for each FAK. Just do. (An “Israeli pressure bandage” might also be a goof addition.)
