"Black Jack non-fibered asphalt emulsion is an odorless, solvent-free, non-combustible
product..." ...according to Black Jack. I'm hoping that this is my last foray into the asphalt
emulsion discussion. I'll admit that the material safety data sheet for this product is different
than for Henry's asphalt emulsion, or others. Maybe its formulated differently? Maybe
everybody just makes this stuff up?

Off gassing is not always detectable by smell, so just because its odorless means nothing. So
perhaps it does off gas, and perhaps it doesn't. Merriam-Webster defines off-gassing as "the
emission of especially noxious gasses". So that puts to rest the notion by an acquaintance
that "even butter off-gasses: you can smell it." We all have different definitions so attempts
at communication flail and fall apart pretty regularly. Oh well. Hot asphalt emulsion isn't
good to breathe, but folks have reassured me that dried asphalt emulsion is inert. Maybe.
The data on the internet seems incomplete as regarding the provision of clear answers on
this subject.
