HOWEVER, this is probably much less of a factor than alll the things that Ken Wittlief mentioned.

I wasn't there, but it is extremely unlikely to have been Homasote. Unless it was really soft and kind of crumbly... Someone else up there in the thread suggeste Masonite, which is more likely. Homasote is an old product that isn't used much anymore.

But, yes indeedy, long term exposure to heavy concentrations of wood dust can be dangerous (mostly nasal and sinus problems), but a couple of days in the presence of Masonite dust isn't going to cause permanent problems for anyone, and won't cause real short-term problems for anyone who doesn't have allergies or asthma.

And OSHA stands for Occupational Safety and Health Administration.
