You are right that I'm by no means an expert in that matter; but when one uses silica sand as a filler for sandbags , he's not working with it, it is kept in a tightly sealed container (sandbag) all the time.
If the bag is leaking sand, in a photo studio, you will do something about right away, trust me.
Which is why I also wrote the following:
Granted, the level of exposure is many times greater than what I presume would occur with incidental usage in sandbags, but let's just put it this way--there are equally effective and less hazardous materials available, so why not use those instead?
Selectively quoting my post and then making a statement that I had already made but you omitted does not mean you rebutted what I said.

oh by the way the bags don't need to be able to hold a human body submerged.
In that case, cured concrete with the body encapsulated in the cement. Works real well for building foundations and basement floorsl Straight from Uncle Looie.

So does the air in any major city, what's your point ?
Seriously, you are plain wrong, unless you do sandblasting for a living.
We have an outfit called the EPA that does actually make sure the air is pretty clean. Now, snow actually stays white, instead of turning a dark gray the next day like it used to.
