I'm not a landowner, but (subject to the local laws of course) I imagine a safer course of action would be decent home insurance. Realistically, there's a thousand other ways things can go disastrously wrong, including nothing that could be the tenant's fault (like natural disasters).

Batteries? Picture a fondue going wrong.

If you've ever dealt with home insurance you try very hard to not have to deal with home insurance.

To say your goals are cross-aligned with theirs would be an understatement.

I'd like to argue that electric Rechauds are superior anyway. Fuel paste or gas always seems to run out just before you're finished, everything cools down while refilling and then you have to get the fluid up to temperature again. Safety around children or tipsy people is just the bonus on top.
