| [Handling] Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. | |
| [Inhalation] May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. | |
| [Skin] May cause skin irritation. | |
| [Eyes] May cause eye irritation. | |
| [Ingestion] May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated. | |
| [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. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure. | |
| [Respirators] A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use. | |
| [Exposure Effects] May cause cancer in humans. Cancer suspect agent. | |
| [Exposure limit(s)] OSHA: Possible Select carcinogen | |
| [Poison Class] 1* | |
| [Appearance] Gray-black microcrystals or black powder. | |
