Sure - but it’s better than being above ground in conditions like this: https://www.youtube.com/watch?v=lUs6iUpa4U4 - watch all the way to the end if you haven’t seen it, really scary stuff. Some of the firefighters evacuated on foot because it was so hot the fire truck started to melt while they were in it — it parts of it had melted when they came back to check the truck after the fire, there were puddles of metal on the road. There’s also footage from a go pro someone setup at their home before leaving, which shows even worse conditions.
I used to live in a fire risk area - one of these bunkers would’ve been great peace of mind. Sometimes you just don’t know if it’s time to evacuate or not, and we were in a valley with only two roads out. When the weather is perfect for fires, there’s never just one fire in the area. Having both our evacuation routes blocked was a very real risk. Some people had homes in a big clearing wiht no tree
Open the air vent, or the port hole (which is just a hole), or open the door a crack, and can spend about two weeks in the bunker as long as you have water with you (which you should).
By then, hopefully someone has reported you missing and the rescue team will clear the fallen tree.
True, I was thinking about all the smoke in the air, but after some time the threat of smoke would go as the fire (at least should have) burnt passed to be safe to open vents.
In the conditions in which you’re jumping into one of these you don’t really want much ventilation - too much heat/smoke, and potentially even the fire burning through some of the oxygen from the contained air. Underground might not be an ideal place to be but IMO it’s likely the best of a set of bad choices if you can’t get out ahead of time - dirt is a pretty good thermal insulator.
I get they are made for short durations but ventilation is all I can think of. not sure I’d want to be underground in that environment
Also, what would a person do if something fell on top of the entrance? Running out of oxygen and trapped inside, sounds like a really warm coffin.
agree. honestly it’s just not the sort of disaster that a bunker is suitable for

you are right, evacuation routes can be cut leaving not much choice

Probably better than inhaling smoke, but yeah. Some provide oxygen supplies, though.
I reckon two people could spend five hours in that bunker safely.
But often you’d only be in there for 15 minutes. It doesn’t take that long for the worst of a fire front to pass by.
CO2 absorbers is not a high tech thing. It can be useful additions.
5 hours is better than I thought, i can see as a last resort in that case it’s better than anywhere else you could shelter
I reckon you would give it a go if it was ‘try it’ vs ‘burn to death’
