Epirider, you didn't ask, but here's a suggestion: why not make him a kit to keep at his mom's house? I've got a step daughter who lives with her mom, and we've made her a kit for both houses. Granted, she's 17 so has considerably more freedom than an 8 year old. I'll bet you'd feel better knowing that he had the basics when he's with her and, speaking as a mom, I bet your ex would feel better such a thing ever happened again.

I recently made a kit for my 10 year old nephew. He's been preoccupied with the possibility of a natural disaster since the recent earthquake in China. He didn't help build the kit but we discussed everything in it, how and when to use it, etc. His mom was a little hesitant, thinking that it might heighten his fear but she says the exact opposite has happened. No more nightmares since he's had his "just in case" pack beside his bed.

I don't think the topic of preparedness is as much of problem as the way we approach it. Once kids become aware of the possibility of emergencies - and especially if they've witnessed one - ignoring that reality isn't an option. Better, in my opinion, to empower the child against their fear by helping them feel and be prepared for "just in case."

That said, I'm not a fan of too much adult driven, specific talk about disasters. I feel it's better to let the child lead. When they're ready to learn more details, they'll ask!
