Not particularly dangeorus.

During Y2K there was some doofus out there who was filling sections of 8" PVC pipe with rice and grains for storage, capping them after tossing some dry ice in to suffocate any varmints that might be living in there. When they blew it leveled his house.

Sounds like urban legend to me. If the pipe is mostly full of rice, there isn't much volume left over for explosive release. Plus, 8" is a pretty big diameter, so bursting pressure is lower than the same schedule PVC pipe in a smaller diameter.

Anyway, schedule 80 pvc is a world away from the thinwall 2 liter bottles I was picturing.

Didn't hear about that one, but I imagine that took a lot more dry ice than will fit in your typical gallon sized jug.

My kid brother and I used to make home brew with yeast. We did about 24 gallons one summer after harvest and stored them in the basement. Three of the bottles exploded one night in fairly quick succession. It made a big mess, but didn't even break the surrounding glass jugs.

Yeast, as you probably know, produces CO2 as it ferments, similar to the effect of dry ice as it melts.

Needless to say, we were a lot more careful with the quantity of the yeast we used after that.
