| [Handling] Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. | |
| [Ingestion] May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated. | |
| [Inhalation] Inhalation of dust may cause respiratory tract irritation. | |
| [Skin] May cause skin irritation. | |
| [Eyes] Dust may cause mechanical irritation. | |
| [Personal Protection] Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
