N.B. Dry rockwool is an "irritant". Before it is moistened, it is scratchy. If rockwool is cut, any airborne dust which you breathe in can be uncomfortable and make you sneeze. Rockwool is not classified as a carcinogen like asbestos, it is an irritant like perlite. If you breathe in rockwool dust, you are likely to sneeze it back out--like any other dust or dirt. Most people simply moisten the rockwool to keep the irritation to a minimum.

If you are allergic to mold, after the rockwool is wetted, you may be affected--use common sense.
If you have emphysema, lung cancer, or any other lung problem, consider wearing a dust mask if you are handling dry rockwool or perlite-use common sense.
This is simply a general advisory, it neither constitutes medical nor legal advice--consult a professional in your state if you are in doubt.
Eat fresh vegetables--they will keep you healthy!
