Carcinogenicity:  This product does not contain any ingredient designated by IARC, NTP, ACGIH or OSHA as a probable human carcinogen.

Existing Medical Conditions Possible Aggravated by Exposure:  Skin irritation may be aggravated in persons with existing skin lesions.  Breathing of dust may aggravate acute or chronic asthma and other chronic pulmonary diseases.

Effects of Single Overexposure:

Inhalation:  May be irritating to the nose, throat and respiratory tract.

Swallowing:  May cause burns of the mouth, throat, esophagus and stomach.  May cause nausea, vomiting, and diarrhea if large quantities are ingested.

Skin Absorption:  Skin absorption through intact skin is likely to be negligible.

Skin Contact:  May cause skin irritation, seen as redness and swelling.  In presence of moisture or sweat, may cause more severe irritation, including burns, following prolonged contact.

Eye contact:  Causes eye irritation.

Effects of Repeated Overexposure:

Skin:  Repeated exposure may lead to irritation and/or sensitivity of the skin.

Other Effects of Overexposure:  Concentrated solution in contact with skin and eyes may cause chemical burns.



INHALATION:  Remove victim to fresh air.  If not breathing administer cardiopulmonary recitation or artificial respiration.  If breathing is difficult or irritation develops, GET MEDICAL ATTENTION.

SWALLOWING:  If victim is conscious and alert, give two or more glasses of water or milk to drink.  Do not induce vomiting.  If vomiting does occur, give fluids again.  Do not give carbonated beverages or weak acids such as vinegar.  Do not give anything by mouth to an unconscious or convulsing person.  GET IMMEDIATE MEDICAL ATTENTION.

SKIN:  Immediately wipe excess material off skin with a dry cloth then wash with soap and plenty of water.  Remove contaminated clothing in a manner which limits further exposure.  Otherwise, thoroughly clean contaminated clothing and shoes before reuse.  GET MEDICAL ATTENTION.

EYES:  In case of contact, immediately flush eyes with plenty of water for at least 15 minutes using an eyewash fountain, if available.  Lift upper and lower lids and rinse well under them.  GET MEDICAL ATTENTION, preferable an ophthalmologist.

NOTES TO PHYSICIANS:  All treatments should be based on observed signs and symptoms of distress in the patient.   Consideration should be given to the possibility that overexposure to materials other than this product may have occurred.

If Burns Result from Overexposure, Treat in the Following Manner:

INGESTION:  Treat asphyxia from glottal edema by maintaining an adequate airway.  Treat shock.  Maintain normal blood pressure by transfusion and by the administration of 5% dextrose in saline.  If symptoms are severe and preformation of the stomach or esophagus is suspected, give nothing by mouth until endoscopic examination has been done.  Maintain nutrition by giving carbohydrate or hyperalimentary fluid intravenously.  Give prednisolene, 2 mg/kg/d in divided doses for 10 days, to reduce progression of fibrocystic and hyaline lung disease.  Esophageal stricture may require dilation.




Stability:  Stable at ambient temperatures and atmospheric pressure.

Incompatibility (Material to Avoid):  Reacts with strong acids.  Can react violently with AL, P2O5 , H2SO4, F2, LI and 2,4,6-trinitrotoluene (1).  This material upon contact with certain food products or their residuals which contain reducing sugars, may react to form deadly carbon monoxide gas.  Proper tank entry and occupancy procedures should be observed.  Monitor the tank atmosphere for the presence of carbon monoxide gas.

Hazardous Decomposition Products:  Carbon dioxide is evolved at very high temperatures (1000 oC) or when mixed with acids.

Hazardous Polymerization:  Will not occur.




Steps to Be Taken in Case Material Is Released or Spilled:  To the extent possible, clean up spillage using shovels, sweeping, or vacuuming.  Avoid dust generation.  Place in appropriate containers for disposal.  Flush area with water.  If spilled on the ground, the affected area should be scraped clean and the material placed in am appropriate container for disposal.  Do not flush material to public sewer systems or any waterways.  Wear appropriate protective clothing and equipment during clean up activities.  Ensure adequate decontamination of tools and equipment following clean up.  Large spills should be handled according to a predetermined plan.

Waste Disposal Method:  Disposal must be made in accordance with Federal, State and Local regulations.




Other Handling and Storage Conditions:  Do not ingest.  Avoid exposure by inhalation.  Avoid getting in eyes or on skin and clothing.  Containers should be stored in a cool, dry, well ventilated area away from foodstuffs or animal feed.  Exercise due caution to prevent damage to or leakage from container.

Protective Equipment Should Be Used During the Following  Procedures:
