Another comment there said it was just "burning polyvinyl chloride" so largely harmless. It wasn't poly vinyl chloride, it was the monomer vinyl chloride, which is a hazardous gas itself (exposure limit 1ppm) and turns into hydrogen chloride and phosgene when burned, which are also nasty.
Posted about this a few days ago and the local glowies said it was just 'hippies talking', lol.
