I do laminate some of them, especially ones that I want to be immediately accessible by others. The Emergency Generator Checklist is laminated. It sits on top of the generator, held in place by the small red toolbox that is used only for the generator.

I've been working on an emergency departure checklist that won't be too overwhelming for my wife to use in my absence. It's a work in progress, but if I ever get it finished it too will be laminated. It might end up being multiple pages.

My kids' BOBs have Emergency Contact Cards that I created and laminated.
