A tempered glass sink basin, when exposed to rapid thermal cycling/stress can fail spectacularly. It appears the sink may not be draining well, and there is no visible overflow protection/relief. There appears to be glass (perhaps tempered) at the faucet with the same concerns as above. The GFCI may not be accessible.
There is a mixture of PVC, ABS, and possibly CPVC under the sink, with the CPVC glued to a PVC 90. Additionally, the drain appears to have a negative slope from the wall to the trap. Finally, the use of a flexible rubber coupling should be a shielded no-hub coupling in above ground applications.
Answer: Yes. According to the International Building Code, all Foam Plastic Materials (not just spray foam, but Styrofoam, sound proofing foams, extruded polystyrene, foam boards, etc.) must be considered flammable (no matter what any salesman tries to tell you.) Different manufacturers’ foams have different flammability. Currently, there are a number of foams that perform over and above the standards required by the International Building Code. However, the literature of each manufacturer’s foam should be reviewed before a project commences. https://greenstampco.com/2011/news/top-10-questions-asked-about-spray-foam-insulation-and-their-answers/

Great questions! Sad I didn’t have time to answer this week. I’m on a boat, barely any internet or cell service.
Looking forward to next week’s though!
