Blasting media safety

["Arnold S. Gilmour" <gilmo004@mc.duke.edu>]

Please be aware that silicosis  pulmonary disease can have as an ideology
coal dust , (black lung), sand, and numerous
other fine particles.  So be safe and don't breathe any of this stuff.  If
you don't have the proper set up it is cheaper to pay someone that does
than to develope lung disease.  My day job is as a respiratory therapist.
    Sincerely,  Arnold
