Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: white solid.
Warning! May cause severe eye irritation and possible injury. Harmful if swallowed, inhaled, or absorbed through the skin. May cause allergic skin reaction. May cause skin and respiratory tract irritation. Hygroscopic (absorbs moisture from the air).
Target Organs: Liver, eyes, skin.


Potential Health Effects
Eye: Causes eye irritation. May result in corneal injury. May cause eye burns. May cause eye injury. Causes redness and pain.
Skin: Harmful if absorbed through the skin. May be absorbed through damaged or abraded skin in harmful amounts. May cause skin burns. May cause reddening of the skin. If absorbed, may cause central nervous system effects. May cause depigmentation of the skin. Produces primary irritant dermatitis, sensitization dermatitis, and skin ulcerations.
Ingestion: Harmful if swallowed. May cause irritation of the digestive tract. May cause liver damage. May form methemoglobin which in sufficient concentration causes cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood). May cause necrotic changes in the gastrointestinal tract. Exposure to very high levels may cause seizures, coma, and death.
Inhalation: May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing, wheezing, shortness of breath and pulmonary edema. May cause cardiac abnormalities. Harmful if inhaled.
Chronic: May cause liver and kidney damage. Chronic exposure may cause visual disturbances. Laboratory experiments have resulted in mutagenic effects. Prolonged or repeated contact may cause possible eczema.

Section 4 - First Aid Measures


Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin: Get medical aid. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
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.
Inhalation: Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. 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: Treat symptomatically and supportively.

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. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion.
Extinguishing Media: Use water fog, dry chemical, carbon dioxide, or regular foam.

Section 6 - Accidental Release Measures


General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation.

Section 7 - Handling and Storage


Handling: Wash thoroughly after handling. Use only in a well-ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
Storage: Store in a cool, dry place. Store in a tightly closed container. Store protected from light and air.

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.
