For my kids:

Fire extinguisher for their apartments, PASS training growing up so they know how to use it, and then get OUT.

Common sense to buy renters insurance. And to look for overhead sprinklers in their units, and pay a bit extra if necessary for the safety afforded.

Smoke alarm and CO detector check when they move in, you'd be surprised how often the detectors have batteries but are years past their prime in rental situations. Rewiring detectors is about as technical as I get.

A packet of 50 $1 bills in their car glove box. Good for a multitude of purchases, and not larger bills so they're less likely to pilfer for pizzas and daily stuff. Still, they tend to use up the dollar bills, but I can easily come up with enough to replace 50 bucks now and again. So if the big shake hits, odds are better they have a modicum of cash nearby, better than most kids.

A crowbar and a BOB, sits in their closets waiting for the day. 2x7.5 gal water containers if they have room (we make room :-)

A big hint to keep their cars gassed up, at least filling when it gets half way to empty. They don't always get this one, but if you instill the logic of filling with a half tank of gas is a lot cheaper than filling a full tank, all it takes is remembering to fill up when it hits the half way point. Doesn't always take, even with me.

My kids on their own take Red Cross CPR and First Aid classes, its all I can ask.

In past years I've given out preparedness themed gifts for Christmas - water storage, flashlights, etc. Everyone gets the same gift, large family so it might be an outlay but well worth doing. I help my family set up water storage and make suggestions for stocking their pantries, putting together family reunification plans after disasters, and each summer we use up oldish extinguishers on a bonfire doing PASS training for the younger nieces and nephews. Its my own version of a culture of preparedness, but I don't try to push it too hard and come off as a kook. One brother takes on the task of keeping laminated wallet cards with family contact info up to date. We're all getting older, we all look out for family.

For my family, I take them camping/ backpacking and introduce self reliance- it's an easy transition to the bigger stuff. While watching TV, specifically The Walking Dead (which is my daughter's favorite), I inject scenarios and ask what she would do; then the other family members jump in and add their thoughts. That's when it goes to he**, but that's the fun of it. Then they all say, "It's ok, daddy will be here." I love it...

For my wife and kids, I do whatever it takes to give them the edge. Training, education, equipment, supplies, money, whatever they need.

For the rest of them, nothing. They have no interest in having a relationship with us. They are free to live their lives as they choose, and I wish them well. They can do what they like, as long as they leave us out of it.
