All dust is harmful to breathe! I once got pneumonia from sanding Honduran mahogany - down for a week. Since wear a mask and use air cleaners when sanding. Other sites state that SC dust is a carcenogen and that sanding without protection will ruin your taste buds for days. Neither is good. Generally the finer the dust, the worse it is for you (goes deeper into the lungs). SC has really fine dust. However - not poisonous ala lacewood, which seems to have some of the same qualities as poison ivy.
All grinder dust is harmful. Just like saw dust or coal dust, it will build up in your lungs causing breathing issues. Wear a dust mask.

Pine shavings are harmful to gerbils because the dust can cloud their lungs and give the respiratory infections. Aspen shavings, though, do not produce any dust and are perfect for bedding.
