First Aid Measures | Back to Contents | 【Ingestion】
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. | 【Inhalation】
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration. | 【Skin】
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Discard contaminated clothing in a manner which limits further exposure. | 【Eyes】
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. |
Handling and Storage | Back to Contents | 【Storage】
Keep away from sources of ignition. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep containers tightly closed. | 【Handling】
Wash thoroughly after handling. Wash hands before eating. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. Use with adequate ventilation. |
Hazards Identification | Back to Contents | 【Inhalation】
Irritation may lead to chemical pneumonitis and pulmonary edema. Causes severe irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma. | 【Skin】
May cause severe irritation and possible burns. | 【Eyes】
Contact with eyes may cause severe irritation, and possible eye burns. May cause eye injury. | 【Ingestion】
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. Causes severe pain, nausea, vomiting, diarrhea, and shock. | 【Hazards】
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. | 【EC Risk Phrase】

Exposure Controls/Personal Protection | Back to Contents | 【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 gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure. | 【Respirators】
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary. | 【Exposure Effects】
Prolonged or repeated skin contact may cause dermatitis. | 【Poison Class】

Fire Fighting Measures | Back to Contents | 【Flash Point】
86 | 【Autoignition】
360 | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Water spray may cause frothing. Cool containers with flooding quantities of water until well after fire is out. | 【Upper exp. limit】
7.3 | 【Lower exp. limit】
1.8 | 【Fire Potential】
Combustible material: may burn but does not ignite readily. |
Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Neutralize spill with a weak acid such as vinegar or acetic acid. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation. |
Stability and Reactivity | Back to Contents | 【Disposal Code】
4 | 【Incompatibilities】
Ammonia, alkylene oxides, amines, caustics (e.g. ammonia, ammonium hydrozide, calcium hydroxide, potassium hydroxide, sodium hydroxide), epichlorohydrin, isocyanates, strong bases, sulfuric acid. | 【Stability】
Stable under normal temperatures and pressures. | 【Decomposition】
Carbon monoxide, carbon dioxide, acrid smoke and fumes. | 【Combustion Products】
Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire. |
