First Aid Measures

Ingestion
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear.
Skin
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

Handling and Storage

Storage
Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from strong acids.
Handling
Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.

Hazards Identification

Inhalation
Low hazard for usual industrial handling. Excessive inhalation may cause minor respiratory irritation.
Skin
Causes skin irritation. Chronic ingestion may cause hypercalcemia, alkalosis, and kidney damage. May also produce milk-alkali syndrome characterized by neurological symptoms such as irritability, lethargy, stupor, and coma.
Eyes
May cause eye irritation.
Ingestion
Ingestion of large amounts may cause gastrointestinal irritation. Expected to be a low ingestion hazard.

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Exposure Effects
Chronic ingestion may cause hypercalcemia, alkalosis, and kidney damage. May also produce milk-alkali syndrome characterized by neurological symptoms such as irritability, lethargy, stupor, and coma.

Fire Fighting Measures

Flash Point
825
Fire Fighting
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. Non-combustible, substance itself does not burn but may decompose upon heating to produce irritating, corrosive and/or toxic fumes. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.

Accidental Release Measures

Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Disposal Code
14
Stability
Stable under normal shipping and handling conditions.
Incompatibilities
Will ignite on contact with fluorine; incompatible with acids, alum, ammonium salts and mercury + hydrogen.
Decomposition
Calcium oxide.
