   I just learned NIOSH is a CDC subsidiary, OHSA and NIOSH decides ppm. Vinyl chloride is IDHL Ca [N.D.]. Ca means its near certainly carcinogenic if ingested and N.D. means not determined.
   
   Ive seen this floating and its a bit misleading. There are a lot of chemicals we don't truly know the rate at which theyre IDLH or hazardous in general just that they are hazardous and possibly how so. It looks like this is one of those. I would probably stay away from any quantity of it because OHSA puts it in the same categories of benzenes and phosgenes. The first image is from AirGas' SDS and the next are from NIOSH (the CDC).
   
   Most of the ppm's and warnings in books like these don't come from experiments but from real world mistakes, accidents, and lessons learned from poor practices. The reason most of your degreasers suck is because when mechanics were using terochloroethylene to wash tools and parts they'd start developing cancer. So the use of things like these were limited and now you have that shitty green stuff lol. Boomers maybe it was not such a good idea to dip your hands in unknown chemicals to grab your wrench that you were cleaning but now we know not to do that ig
