All sand is silica (more or less). People get lung disease from
breathing coal dust, cotton dust, silica dust, asbestos dust, concrete
dust,... Can we detect a common theme here? Wear a dust mask when you
are pouring the sand from its bag into the smaller containers. After
that, you (or the students) are unlikely to breathe significant
quantities. (I would not bet a nickel that flour dust is any safer than
any of the other dusts!!)
