Can sched 40 be run in a crawl space in a quadplex? I thought I have heard something about this being illegal due to potential chemicals in a fire from burning PVC. Can't find any code preventing this. Any opinions would be appreciated

No, it's fine. The problem is running it in an area that is considered a plenum or has some limits here in the air handler closet.

I don't believe its in the NEC, but I was once told the same thing about pvc in a common area of an office space, in a hallway.

Also, be aware of 352.12(D)

(D) Ambient Temperatures. Where subject to ambient
temperatures in excess of 50°C (122°F) unless listed
otherwise.
