EMERGENCY OVERVIEW
Contact with water liberates highly flammable gases. Toxic if swallowed. Causes burns.Corrosive.Hygroscopic.
Potential Health Effects
Eye:
Causes eye burns. May cause irreversible eye injury.
Skin:
May be absorbed through the skin. May cause severe skin irritation with possible burns, especially if skin is wet or moist.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema.
Causes severe irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma.
Chronic:
Prolonged or repeated skin contact may cause defatting and dermatitis.

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Get medical aid immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
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.
Notes to Physician:
Treat symptomatically and supportively.

General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. Combustion generates toxic fumes. Water Reactive. Material will react with water and may release a flammable and/or toxic gas.
Extinguishing Media:
Do NOT use water directly on fire. Water may be ineffective. Use approved class D extinguishing agents or smother with dry sand, clay, or sodium bicarbonate.
Autoignition Temperature: 250 deg C ( 482.00 deg F) Flash Point: 400 deg C ( 752.00 deg F) NFPA Rating: Not published.
Explosion Limits, Lower: 3.02 vol % Upper: .00 vol %

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions.

Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Keep container tightly closed. Do not get on skin or in eyes. Do not ingest or inhale. Do not allow contact with water.
Storage:
Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Water free area.

Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHAs eye and face protection regulations in 29 CFR 1910.133.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29CFR 1910.134. Always use a NIOSH-approved respirator when necessary.
