When I have been involved in providing guidance on HF spill kits, I strongly recommended calcium carbonate. There is a reasonable chance that is one ingredient in the 'HF spill kit'. Try adding an acid (vinegar) to the material in the kit and see if you observe an evolution of gas (CO2)

Brandon,
I was reading the MSDS for Clift Industries HF Acid Eater and I was unable to determine the contents of the spill absorbent material (Inorganic Salt Solutions is too vague as an ingredient list).
I would recommend that you ask the manufacturer if HF Acid Eater can neutralize regular mineral aids (I doubt it). Their contact information is as follows:
Clift Industries, Inc.
PO Box 67153
Charlotte, North Carolina 28226
800-996-9901
704-752-0031
Fax: 704-544-2532
Lastly, the MSDS indicates that the product itself is not a RCRA hazardous material.
Hope that helps.

Brandon,
It will depend entirely on what is in the "HF Acid Eater Kits". If something will neutralize the H+ part of an acid, then it might just possibly work for all acids. If it only "neutralizes" the F- component, then it might only work for HF and acid fluoride compounds (such as BF3). I'll leave the calculations to the physical chemists in the group as to how much would be needed to "neutralize" how much. I would suspect some sort of calcium or magnesium component, which would be useless for acids other than HF except as an absorbant. The corrosive risk would still be there.
I'd suggest ordering and stocking something more appropriate and diposal of these "Kits" as appropriate.

CHAS,
I recently discovered that my department has a number of HF Acid Eater spill kits in stock, yet no lab within the university currently uses HF. I also discovered that we are completely out of standard acid spill kits. My question is, can an HF spill kit be used on other acids? The kit MSDS does not list ingredients so I am a bit in the dark regarding its active component.
Thanks,
