Firestop/fire protection questions

Hey! I'm looking for some insight on firestop caulk or collars. I've just done my best looking through 300+ page PDFs on 3m and hilti's websites but I'm getting lost. I run a small shop with my dad and we don't do a ton of commercial and certainly not a building with 8" concrete floors. What is the best way to find out which type of firestop I will need for my PVC penetrations through the floors, as well as the copper penetrations. It sounds like maybe I will need the collars for PVC but can anyone confirm that? Or does this all have more to do with my local code? Any advice would be much appreciated. Thanks!
