Once a year grab your oldest fire extinguisher and least proficient family member and hold a live fire(literally) training exercise.

It helps a bunch in an emergency when you are not preforming a technical operation for the very first time.

I will concede this may be tricky to pull off in a more urban environment, "Yes officer that's the idiot who lit his garbage can on fire in the middle of the street", in which case do without the fire, or make friends with the local fire department and they will let you do it in their parking lot.
