I hear ya. Firefighting's so complicated, our departments require a masters just to get in the door. If you actually want to fight fires, it's a PhD or GTFO.
Umm, what exact experience/training do you have with firefighting and the dangers associated with it?
The basic concept of putting fires out is simple, but as with everything else "The devil is in the details."
I will go with one basic tenet of all emergency services, life above property. If he was exposing himself to sufficient smoke to require treatment, he was in a position of risking LIFE for PROPERTY. But he was not just risking his life. He was also risking MY LIFE, or MY BROTHER'S/SISTER'S life.
Don't get it?
If he had been incapacitated by the smoke, what next? Oh yeah, the FIREFIGHTERS would have had to go in and rescue him.
When all along, he had the means to be in a position of safety.
Think he had the exits available if he became endangered, and that's not an issue? I'm sure he is intimately familiar with say the symptoms of cyanide poisoning, and when he needed to remove himself from that environment prior to incapacitation.
And if I need to explain why cyanide symptoms would be an issue....
