"Fluorosilicic acid is a waste product of the phosphate fertilizer industry and is heavily contaminated with toxins and heavy metals (including the cancerous arsenic, lead and cadmium) and radioactive materials. This substance is the waste residue from the superphosphate fertilizer industry, and about 70 to 75 percent of this stuff comes from the Cargill fertilizer manufacturing company.
I used to haul alot of this **** off and the company I worked for told us never take off your gloves or mask when loading or unloading it. If it was "SAFE" then why where all of us drivers told to wear gloves and masks? I think you need to dig alittle deeper before you open your trap.
