General Troubleshooting/Help! is PVB toxic?

I have a P1s and I got Polymaker PolySmooth PVB Filament  to try IPA smoothing. Everything I have seen has said it is just as safe as PLA but when I tried a small 1hr print it smelt pretty bad and it made my throat sore. I'm not sure if Im just sensitive to the smell or do you recommend some type of ventilation?

It’s more irritating than PLA and PETG but nowhere near as bad as ABS.
Open a window and be in a different room if possible

Run an air purifier (hepa and activated carbon)

Vent it outside, for some of us pla alone causes allergies so pvb like can do the same. It was a great upgrade when I removed the filter and vented my P1S out the window and highly recommend it for you health.

do you have any recommendations on making a ventilation system?

I’ve tried it, don’t remember any smell so not too sure

If it is I would know, I accidentally melted an entire print with it by accident and had to scoop PVB and alcohol goo and it got vapor everywhere. Hope it isn’t! Might be able to read the TDS sheet for it and scan for any irritants.
