Bentonite is considered a nuisance dust; therefore, we recommend wearing a P3 Mask. Keep working areas free of dust by cleaning up with a damp sponge.

In keeping with our overall general advice, we suggest wearing full PPE when handling raw materials. This includes a mask, safety
glasses, and gloves.

It is a sensible precaution for children not to work with raw materials.
