| [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. | |
| [Ingestion] May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated. | |
| [Inhalation] May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. | |
| [Skin] May cause skin irritation. The toxicological properties of this material have not been fully investigated. | |
| [Eyes] May cause eye irritation. The toxicological properties of this material 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. | |
