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.
One of the easiest ways to clean small parts is to blast them with an abrasive compound. An abrasive blast cabinet or bead blaster is a metal box in which a compound is propelled toward your parts using air pressure. The cabinet has a glass window so you can see what you are doing and integrated rubber gloves so you can handle the parts without blasting your hands.
