I have a question about blasting media that was posed to me today and I welcome input on an answer... Conventional blasting media for paint removal is sand, which can pose a risk of silicosis workers. A company is promoting a "slag abrasive" as a safer, environmentally friendly alternative to sand. Any P2TECHies heard about this or have a comment? Thanks, Michaek Keefe email@example.com Tetra Tech EM, Inc.
