Tweva glad to see your well. Thought this post might be because of your own loss from the title.
I’d like to chime in.
There are 3 components to fire. Fuel, heat & oxygen. Control all your ignition sources and keep them separated fuel. The majority of residential fires have electrical deficiencies as an ignition source. If you have a poor electrical system/wiring get it fixed.
Use smoke detectors, without them the CO from a fire (carbon monoxide) will put you under and you will never wake up. You will not believe how fast a uncontrolled fire spreads in a house. It just takes a few minutes to involve whole rooms.
