First Aid Measures

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 to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Handling and Storage

Storage
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Handling
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.

Hazards Identification

Inhalation
The toxicological properties of this substance have not been fully investigated. Inhalation of dust may cause respiratory tract irritation.
Skin
No information regarding skin irritation and other potential effects was found.
Eyes
Dust may cause mechanical irritation. No information regarding eye irritation and other potential effects was found.
Ingestion
The toxicological properties of this substance have not been fully investigated.

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 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 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Exposure Effects
Hyperventilation, mild rapid heart rate and elevated body temperature are common; abnormally low blood pressure may develop in severe overdose. Lethargy, agitation and confusion may be early findings in patients with severe toxicity. Coma and seizures may develop subsequently. Cerebral edema is a common autopsy finding. Chronic maternal ingestion is associated with an increased incidence of stillbirths, antepartum/postpartum bleeding, prolonged pregnancy/labor, and lower birth weight.
