Good points. Valuable reminder.

Security of packing, sealing the containers, will always be a compromise between easy access and being bombproof. I tried sealing my first-aid kits with foil tape but they weren't much good for first-aid sealed that way. By the time I cut through the scrim reinforced foil tape we could have built a hospital.

If you use unreinforced tape you can sometimes lay a bit of wire under the tape to make a 'rip-strip' that speeds access. Be sure to try this a few times at home to get a feel for how to maintain a seal and work right.

Careful consideration of what might be be needed quickly should guide the order you pack stuff. A tourniquet and a couple of combination dressings ride on top of my immediate use medical kit. I can whip them out without even loosening the satchel straps. Quickly at hand is good.
