Draw inspection today on a home where they were spraying polyethylene (soy-based) insulation. Respirator required near the spray area. Very toxic!
Look for excessive cracking and poor adhesion with this stuff.

Toxic soy beans?
I know beans can give you gas, but I didn’t think they could REALLY kill you!
Tofu, sauce, fuel, insulation and…pretty remarkable plant
United Soybean Board ](http://www.unitedsoybean.org/)

BioBased Systems (spray foam insulation)
Construction Polymers International (spray foam insulation),
BioPolymers (foam insulation)

If it is like foam board It must be fire protected (like foam board) I think it can gives off gas. (Cyanide I think )
On their web site it says it must be covered . Write it up.

PS…
If you’re standing and spraying over your head, it’s not a crawlspace…:mrgreen:
I talked to the contractor for about half an hour. He explained the whole process. He talked mostly about parts A and part B (in color-coded drums in the back of a truck) and how they ran in separate tubes to the gun and once they left the nozzle, cured in 10 seconds. The line carrying parts A and B has to be heated. In all that time he said nothing about soy beans though, and more’s the pity becuae they are a pretty amazing bean as Barry points out.
walk space!
If I can walk it, it is known by another name.
A basement.
Hope this helps;

In my area, it all depends on the floor finish.
Any area 18" to 18’ high is a crawl, if the floor is earth and requires ventilation and vapor barrier.
If the area has a concrete finished floor, it a basement or anything you want to call it.
