I disagree with Pam - Hi-bor doesnt have arsenic in it - the old CCA did.
Here is the MSDS for Hi-Bor : http://hwthawaii.com/pdf/Hi-BorTreatedWoodmsds.pdf
From the MSDS, it pretty much sounds like inhaling the saw dust is the big issue. I would suggest that if you do use it for mulch you were a mask while you mulch and then use the mulch for only ornamental vegetation.
