First Aid MeasuresBack 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. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
【Skin】

Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
【Eyes】

Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes).
Handling and StorageBack to Contents
【Storage】

Keep away from heat, sparks, and flame. Keep away from sources of ignition. Keep container closed when not in use. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from strong acids. Keep away from organic halogens.
【Handling】

Wash thoroughly after handling. Use only in a well ventilated area. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Do not ingest or inhale. Use only in a chemical fume hood. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Hazards IdentificationBack to Contents
【Inhalation】

Corrosive. Toxic by inhalation. Vapors cause irritation to the respiratory tract; symptoms may include sneezing, coughing, nausea, difficulty in breathing, and pulmonary edema.
【Skin】

Corrosive. Contact can cause redness, pain, and skin burns. Can be absorbed through the skin causing systemic poisoning.
【Eyes】

Corrosive. Liquid contact will produce severe eye injury. Vapors are irritating, causing redness, pain, blurred vision, lacrimation, conjunctivitis, and corneal edema. Corneal injury may be severe and extensive, and if not treated promptly, could result in permanent impairment of vision.
【Ingestion】

Corrosive. Toxic! May cause burns of the mouth, throat, and stomach with severe abdominal pain and collapse. Aspiration into the lungs may occur during swallowing or vomiting, resulting in lung damage.
【Hazards】

May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Exposure Controls/Personal ProtectionBack 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 protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
【Respirators】

A full facepiece respirator with organic vapor cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator.
【Exposure Effects】

May cause secondary burns to skin from long exposure. Animal studies have shown target organ effects on heart, liver and kidneys.
【Exposure limit(s)】

TLV: 10 ppm; 41 mg/m3 STEL: 15 ppm; 62 mg/m3 (ACGIH 1993-199?). OSHA PEL: TWA 25 ppm (100 mg/m3) NIOSH REL: See Appendix D NIOSH IDLH: 200 ppm

【Flash Point】

-9
【Autoignition】

249
【Fire Fighting】

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Use water spray to keep fire-exposed containers cool. Water may be ineffective. Material is lighter than water and a fire may be spread by the use of water. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. May polymerize explosively when involved in a fire. Containers may explode when heated. Extinguishing media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Do NOT get water inside containers.

【Fire Potential】

Flammable/combustible material.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation. A vapor suppressing foam may be used to reduce vapors.
Stability and ReactivityBack to Contents
【Disposal Code】

5
【Incompatibilities】

Acids, oxidizers, chlorine, hypochlorite, halogenated compounds and nitrogen tetraoxide. N-nitrosamines, many of which are known to be potent carcinogens, may be formed when this product comes in contact with nitrous acid, nitrates or atmospheres with high nitrous oxide concentrations.
【Stability】

Stable under ordinary conditions of use and storage. Strongly alkaline; will undergo strong exothermic reaction with acids to form amine salts.
【Decomposition】

Nitrogen oxides, carbon monoxide, carbon dioxide.
【Combustion Products】

Toxic gases and vapors (such as oxides of nitrogen and carbon monoxide) may be released in fire involving triethylamine.
