Cobalt oxide is harmful if swallowed, will cause damage to lungs and is a hazard to the environment. We suggest wearing a P3 mask, safety glasses, gloves and work in a well ventilated area. Please dispose of responsibly and do not use in a domestic environment. Do not eat or drink in your workspace. Keep working areas free of dust by cleaning up with a damp sponge.

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