You can use normal sand pit sand for a sand bath, it keeps them trim by sanding them down while they dig..
You'd need to thoroughly dry the sand in the oven first, even if it somes 'dry' it's probably wet.
p@h only sell chinchilla DUST, as far as I am aware, chinchilla sand is recommended because it can pass between the hairs of the hamster, but syrians don't tend to use it that way (it's more a dwarf thing)
The sand won't hurt their respiratory system, but chinchilla dust would.. as far as I know sand for a sand pit is fine
