Dry Clay - Many materials used by potters in glazes and clay are potentially hazardous substances. We at Bailey feel you should take precautions to minimize exposure. 1. Handle materials carefully. Avoid spillage. Keep materials covered. 2. Wear a NIOSH approved respirator. Avoid breathing all dusts. 3. Wear rubber gloves when glazing or painting with oxides or stains. 4. Keep your workspace clean, free of dust. 5. Wash your workclothes separately from other clothing. 6. Do not eat or smoke in your workspace. 7. Use a wet mop for cleaning or a toxic dust vacuum cleaner. Material Safety Data Sheets (MSDS) are available on CD-ROM's in PDF format. Please call 1-800-431-6067 for more details. A CD-ROM disk can be enclosed with your order upon verbal request.
