Forgot a few more things- make sure your smoke and carbon monoxide detectors are well-placed, have fresh batteries every six months, and no older than 10 years.
Buy or have a kitchen fire extinguisher, heck yearly to be sure the needle is currently in the green.
I had a talking smoke detector placed right above our bed (he would be up all hours at night)- it shouts a warning plus the alarm noise, figured that would get me up when my hearing aides were out.
AND I would remind myself that if he set the house on fire, we could get out and we have good homeowners insurance to start over with whatever.
