Industry document says PFAS are ‘highly toxic’?

This morning I came across this story in The Guardian.

The Guardian article interested me in a point of history about PFAS that I thought might be covered on the Wikipedia page for PFAS. There I found this:

So I followed the footnote for the highlighted section to this industry document:

So like many other chemicals, PFAS is toxic when inhaled or injected. No surprise. But that is not how exposure to PFAS generally occurs and certainly not the way it occurred in the Guardian story. Note that absent a couple cases of “dermetitis” [sic] caused by “temperature and moisture”, “there have not been any indications of toxicological effect of chemicals.”
