It really does not matter. The issue is the relationship of OA vapor to 
other toxic chemicals. It is very toxic.

I would not use it. I toyed with the idea until I saw just how dangerous 
it is.

Whoever is using it with others is exposing the helper (as well as 
themselves) to potential harm and opening themselves up to a serious 
lawsuit if an accident happens.
