Beryllium-containing coal-slag dust
Dust generated when abrasive blasting uses coal-slag media that may contain beryllium.
Airborne form
dust
The form describes what is suspended in air at the point of exposure. A material can produce more than one form, such as dust during handling and fume during heating.
