For Gritty Mix, how dangerous is DE when working with it?
I imagine that when working with Napa Floor Dry (DE), one should use a mask.
Does Napa Floor Dry fall in this category? The thing is that even after screening it, if we have Gritty Mix in a big container, and someone goes in and sifts around, dust particles can come up.
If this is a dangerous product I may try to find something else. What are people's thoughts on this?
