Section 3 - Hazards Identification


Appearance: colorless or slight yellow liquid.
Danger! May be fatal if inhaled or swallowed. Exposure through inhalation may result in delayed pulmonary edema, which may be fatal. Onset of acute lung injury after toxic exposure may be delayed up to 72 hours after initial exposure. Causes burns by all exposure routes. Reacts violently with water.
Target Organs: Respiratory system, eyes, skin.

Potential Health Effects
Eye: Causes severe eye burns.
Skin: Causes skin burns. Causes redness and pain. May lead to the formation of blisters.
Ingestion: May be fatal if swallowed. Causes digestive tract burns with immediate pain, swelling of the throat, convulsions, and possible coma. Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal.
Inhalation: Causes chemical burns to the respiratory tract. Causes corrosive action on the mucous membranes. Inhalation may produce burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Exposure through inhalation may result in delayed pulmonary edema which may be fatal. Death may result hours after initial exposure.
Chronic: Chronic exposure may cause effects similar to those of acute exposure.

Section 4 - First Aid Measures

Eyes: Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed. Extensive irrigation with water is required (at least 30 minutes).
Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion: Call a poison control center. If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician: Exposure may result in death. The effects may be delayed therefore medical observation is essential.

Section 5 - Fire Fighting Measures

General Information: As in any fire, 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. Contact with water can cause violent liberation of heat and splattering of the material. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Containers may explode when heated.
Extinguishing Media: Do NOT use water directly on fire. Use carbon dioxide or dry chemical. Contact professional fire-fighters immediately.
Flash Point: Not available.
Autoignition Temperature: Noncombustible
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating: (estimated) Health: 4; Flammability: 0; Instability: 2; Special Hazard: -W-

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation. Evacuate unnecessary personnel.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Wash thoroughly after handling. Follow all MSDS and label precautions even after container is emptied because they may contain product residues. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Do not allow contact with water.
Storage: Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
