[Clayart] sand and health

[Joseph Herbert]

Hey, Ron

Good point, I was not addressing the health implications at all.

The worst situation for injury is dry machine crushing (or any mechanical
operation, like sieving) of silica containing material.  Yields small sharp
particles, easily airborne, easily inhaled.

In lots of operations, and in studios, a primary operation is carried out
wet (diamond sawing, say) and the fine particles are not airborne.
However, if the slurry is not contained, it will dry and if human or
vehicle traffic is present, the fines are launched into the air.

We all need to be more mindful of dust !

Joe
