Talked to a building inspector about firestop and it changed my whole view

I was finishing up a pour for a strip mall foundation in Springfield last week, and the inspector was checking the floor above. He pointed at a simple pipe penetration and said, 'That little gap is a highway for smoke. The whole assembly fails if you don't seal it right.' I always thought firestop was just red caulk, but he explained it's a tested system for each specific opening. Has anyone else had a job where the firestop specs were way more detailed than you expected?

That "highway for smoke" line explains a lot of building codes.

I read an article about how the Great Chicago Fire changed building rules. They started requiring brick walls and wider streets to stop fires from spreading. That highway for smoke idea makes total sense now.

But is it really that big of a deal? Seems like common sense to build stuff that doesn't burn down so easy.
