"'Dangerous' is contextual...if the risks of a task can be mitigated with some basic safety process, is it still dangerous? Getting into a grain bin is like rock climbing...go commando and you're playing with death, go in with the right process and gear and you'll be fine. Is it still 'dangerous' then?"

I think this is a flawed analogy.

Although I don't do much rock climbing, I do take part in some other high consequence recreational activities. I agree that some of these risks can be mitigated with equipment and safety measures and, in fact, I don't feel like I'm courting death.

The difference here is that these are activities I have tens of thousands of reps of. Further, I am regularly practicing these activities in totally safe environments. Finally, I have mental models of thousands of different routes and locations and conditions and settings upon which to draw.

Contrast this with (for instance) entering in, and working on, a grain silo. You will not have had thousands of reps of this activity. You will not have entered thousands of different grain silos. You will not have trained for decades in practice grain silos. This is a very high consequence activity that you will have very shallow mental maps of.

I think that's an important distinction.

It suggests that regardless of equipment and processes, one should enter into (high consequence activities one has shallow mental maps of) on very high alert.
