| [Flash Point] 119 | |
| [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 container tightly closed. | |
| [Inhalation] Material is extremely destructive to the tissue of the mucous membranes and upper respiratory tract. May be harmful if inhaled. | |
| [Skin] Causes burns. May be harmful if absorbed through the skin. | |
| [Eyes] Causes burns. Lachrymator. | |
| [Ingestion] May be harmful if swallowed. | |
| [Hazards] Emits toxic fumes under fire conditions. | |

| [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 particle respirator type N100 (US) or type P3 (EN 143) 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] Inhalation may result in spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin. | |
