One would hope that a kid left behind would be old enough, and have been taught to think enough to use what has been left behind, which is most of what you own.

Personally, I wouldn't leave an oxygen tank and firestarting materials for a kid. Oxygen in a confined space + a spark = explosion.

If you have a plan for truly serious conditions, you'd better make sure the kids know all the ins and outs of the equipment they are likely to be left with.

Considering the lack of mental agility of the kids today, without their constant surrounding of phones, computers, electronic toys, and total lack of any kind of sense, they would probably wander away from a site that had survival equipment right there, crying and feeling sorry for themselves, and die of exposure, dehydration or starvation. A chihuahua has more survival instinct than your average American kid.

Teach your kids while you have the chance.
