I’ve started fermenting in a corny keg recently with a spunding valve, seemingly to good results (I love the fact that it’s a cheap multi-purpose stainless steel vessel), but I’ve heard it can be discouraged as if the spunding valve outlet gets clogged, it can lead to some “dangerous situations”. The recent post about a brewery staff member dying from an exploding keg means that the danger is a real one, even with commercial experience and controls.
Are there any extra preventative measures I can take, beyond using a spunding valve and PRV valve as backup in the keg lid, to ensure that I do this safely?
It's completely stupid, especially when carbon itself is untaxed. You're spending $1B to suck something out of a vast and difficult medium that's getting chucked up there willy nilly by anyone who wants to? Why not spend the money putting systems in place to block its initial exhaust? It would be far more cost effective.
