new shop floor question

I checked the archives & rcm's archives with only ltd. success. I'm designing for an immediate build (moving) a new shop barn of my dreams. I
will have a partitioned area for my blacksmithing & other "dirty" metalworking (grinding, welding, cutting, etc.). The whole shop (30x100) will be on a concrete slab. What if anything should I put down over the slab in this area?? Dirt, sand, etc.??? Thanks for all responses!!

I poured a concrete slab for my shed with a 3inch square lip, I then put a 3in layer of "crush and run" down (this is mixed ungraded stone from a quarry from from about 2in diameter to dust).
Compress it down with a tamper (I used a garden roller).
It's now set like stone, but without the worries of it spalling.
I imagine a mixture of soil, sand, ash, clinkers and gravel would work as well - assuming you are under cover, otherwise, whats wrong with grass?

Hack to size. Hammer to fit. Weld to join. Grind to shape. Paint to cover.

Thanks for your respose & sorry for the delay in my acknowledgement. Was in major accident at first of month & life is just now starting to look somewhat normal. The area is going to be inside a much larger structure with multiple functions. This area for the forge will only be partitioned off, not sealed, from woodworking, auto mechanics, and clean metalworking (mill & lathe) work areas. Was trying not to track sand throughout and would have same problem with ashes & dirt. Mixed sizes of smaller gravel & stone might be my answer, as long as there's no local flint in it. Thanks.

Forge and woodworking (and auto-fuels/lubricants, too) without walls sounds like a recipe for a shop fire - not a happy thought.
