| [Fire Fighting] Extinguish with water spray, carbon dioxide, dry chemical powder or appropriate foam. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. | |
| [Ingestion] If swallowed, wash out mouth with water provided person is conscious. Call a physician. | |
| [Inhalation] If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen. | |
| [Skin] In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician. | |
| [Eyes] In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician. | |
| [Storage] Keep tightly closed. Store in a cool dry place. | |
| [Inhalation] Material is irritating to mucous membranes and upper respiratory tract. | |
| [Hazards] Emits toxic fumes under fire conditions. | |
| [EC Risk Phrase] 36/37/38 | |
| [EC Safety Phrase] 26 37/39 | |
| [Personal Protection] Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing. | |
| [Respirators] Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. | |
| [Exposure Effects] Causes eye and skin irritation. May be harmful by inhalation, ingestion, or skin absorption. | |
