I did a job a long time ago and the inspector said that pvc wasn't allowed overhead in a concealed area, because if it was to catch fire it would give off toxic fumes. Has anyone heard of this, or did I misunderstand him? I haven't seen this is the code, but maybe it is in a local code or something?? I've only seen that it is not to be used if ambient temperatures are in excess of 122 degrees Far. I guess it's feasible that it will get that hot in attic of course. I've been in some that felt that hot. Thanks for the input.

352.12 (uses not permitted) is where the 122 degrees is mentioned, unless the PVC is 'listed' for higher temps.

Another spot is a rated ceiling assembly, and fire rated construction.
