EMERGENCY OVERVIEW
Harmful in contact with skin. Toxic if swallowed. Irritating to eyes and skin. May cause sensitization by skin contact.Hygroscopic (absorbs moisture from the air).Heat sensitive.
Potential Health Effects
Eye:
Dust may cause mechanical irritation. Causes severe eye irritation.
Skin:
Causes severe skin irritation. Harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. Causes digestive tract irritation.
Inhalation:
Dust is irritating to the respiratory tract.
Chronic:
No information found.

Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion:
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 immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Antidote: None reported.

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. Combustible solid. May be ignited by heat, sparks, and flame.
Extinguishing Media:
Do NOT get water inside containers. Use dry chemical, dry sand, or carbon dioxide.

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. Provide ventilation.

Handling:
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed.
Avoid ingestion and inhalation.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible substances. Keep refrigerated. (Store below 4C/39F.) Keep containers tightly closed.

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.
