How about expendable shot blasting media such as aluminium oxide or copper slag?
I think that whatever you choose there will always be a certain element of it that is harmful to health and would agree that welding and grinding are of greater cause for concern.

I would think small stainless balls would be the safest, can’t turn into dust or rust but very expensive. I looked into it one time and came up with over $200 to fill my large bag. Expensive but have you priced new lungs lately ? ~ John Buchtenkirch

Pounding Sand
Lots has been written in different threads re: dangers of silica.
Taking more than a hint from Gareth, Quote:

It comes in 4 grits: extra fine through coarse. Here's the fine grit, works just fine in my blast cabinet. Also pounds just like the sand I removed from my bag, and no dust emanating from the Velcro closure like the play sand had.

Mix some mineral oil. Also known as baby oil in with your sand bag sand. No more dust. And the bag is tighter.
Try it. Mike |
