I was a volunteer fire-fighter for 3 years.
If my house was on fire, I have some training (if no SCBA gear). And - most importantly - I know the lay of the land - the layout of my house, and where my wife has stacked stuff (boxes of donations, and other stuff).
I’d be better off in the house than a fire-fighter who does NOT have any idea the floorplan of my house, or the obstructions.
That said, having the training and using it are two different things.
Agreed entirely. My father was a volunteer firefighter as well. As you indicated, the training is important and I do believe training will kick in when needed most of the time. In a training exercise, my father and another fireman were accidentally (truly) left on the second floor of a burning house in zero visibility when the third man on the hose left with the hose. All three of them got an unplanned opportunity to use their training that day.
