NFPA 484 2015 EDITION â STANDARD FOR COMBUSTIBLE METALS REVISIONS AND THE ABRASIVE BLASTING INDUSTRY. Abrasive (media) blasting is a process that does in fact generate dust and in many applications, a combustible metal dust. However, until the 2015 edition of NFPA 484 abrasive blasting hasnât been included or listed as a process within the standard.
Prolonged abrasive blasting can remove an object's chrome finish, though touch-up work may need to be done on the object's hard-to-reach areas afterwords. 1  You may want to use a relatively fine-grain medium (for instance, 400-grit sand) when blasting your chrome to prevent damage to the underlying metal.
