The ingestion/breathability table might be more restrictive. Like, elemental Sulfur is perfectly fineno actually it’s not fine— but probably unpleasant to lick. Contact dermatitis likely but not life threatening—just one lick, ok; promise no more? ;)
Breathing elemental Sulfur is also going to result in contact dermatitis -inside the lungs. Which is going make a really bad day.
Don’t lick carbon nano tubes or buckyball. Also in general carbon powder can be a particulate inhalation issue.
The table is about licking specifically. It’s not a breathability table. Just so that is clear.
I assume if it’s getting anywhere near your mouth you’d also be breathing it but aside from that, ingestion is also a nogo.
