Safety of abrading cadmium plating


When abrading a surface that is Cadmium plated should precautions be in place for the plating that is being removed? i.e., rubber Protective Gloves [linked by editor to product info at Amazon], face mask? Can the material being removed be absorbed through contact with your skin?

Without knowing the details, I think everyone would agree that breathing cadmium dust is not a good idea.

Cadmium plating is almost always chromate conversion coated, and the chromate could probably be absorbed through the skin to some extent.

When working with a toxic material like hexavalent chromium, plus a cumulative poison like cadmium, I certainly think you need proven local ventilation.

I don't know the details of your situation, but it might be better to chemically strip the chromate and cadmium before machining.
