Somehow I skipped this one. We have one story house with windows in each bedroom and fire extinguisher & smoke alarms. It would be difficult for disabled person to get out of window so will work on that.
I had a house fire before (wasn’t home and cause not determined) and later on when neighbor’s house burned, went over after calling fire dept put kids in my care that was parked out of way of fire dept and tried to put out fire till time to get OUT and then grabbed an armload of coats and boots on the way out. Soon windows blew out, and house was a goner.
