What makes a wood a sensitizer? I understand that a sensitizer makes your system sensitive to many, or any wood dust....but how and who determines if a given wood is a sensitizer, vs. an irritant?
Cherry wood is never listed, does this means it's safe?
It seems every wood dust is problematic..... I assume what this means is, all fine dust is problematic, not just wood. For example, would fine dust from dirt be as problematic as many of the low to mid toxic woods? Same true with grain dust?
I have a suspicion much of this science is at its VERY early stages.....
