First Aid Measures
【Ingestion】Emesis is not indicated due to the irritant nature of these agents. Charcoal - not recommended; it may promote vomiting and make endoscopic evaluation difficult. Immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 4 ounces/120 ml in a child). Neutralization - neutralization is not indicated. Although these agents are irritants, and therefore should not produce tissue damage, it is almost impossible to assure that a particular substance under a particular set of circumstances would not cause damage. Therefore, each patient should be examined with the idea that mucous membrane damage might have occurred.
【Inhalation】Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
【Skin】Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water.
【Eyes】Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. If in a medical facility, sterile saline should be used to irrigate the eyes until the cul de sac is returned to neutrality. Some alkali exposures may require prolonged irrigation.
Handling and Storage
【Storage】Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
【Handling】All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Hazards Identification
【Ingestion】Nausea, vomiting and diarrhea are possible if ingested.
【Inhalation】Cough, tachypnea, and wheezing are common after inhalation.
【Skin】Redness, swelling and pain may occur.
【Eyes】See Skin.
【Hazards】Dangerous when exposed to heat or flame. Can react vigorously with oxidizing materials.

Fire Fighting Measures
【Flash Point】43℃
【Autoignition】285℃
【Fire Fighting】Use water in flooding quantities as fog. Solid streams of water may be ineffective. Use alcohol foam, dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. Use water spray to knock-down vapors. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources.
【Fire Potential】Flammable/combustible material. May be ignited by heat, sparks or flames.
Accidental Release Measures
【Small spills/leaks】Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Apply water spray or mist to knock down vapors. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. Water spill: Use natural barriers or oil spill control booms to limit spill travel. Remove trapped material with suction hoses.
Stability and Reactivity
【Incompatibilities】Incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides..
【Stability】No data.
【Combustion Products】Fire will produce irritating, corrosive and/or toxic gases.
