I use those pretty often, but the ones I use are not reusable, so when it's too low to be usable I just leave it open near the window and you almost can't even smell it, I once made the mistake of throwing one to the trash though, that's a bad idea.A single propane canister won't hurt things much unless you're in an enclosed space or light the sucker up all at once. It will dissipate pretty quickly if leaking outdoors.
