Section 3 Hazard Identification (Also see section 11)
Generally not hazardous in normal handling, however good laboratory practices should always be used. Avoid long term exposure to skin or by inhalation. 
Section 4 First Aid Measures
Generally not hazardous in normal handling, however good laboratory practices should always be used. Avoid long term exposure to skin or by inhalation.

FIRST AID: SKIN: Wash exposed area with soap and water. If irritation persists, seek medical attention.

EYES: Wash eyes with plenty of water for at least 15 minutes, lifting lids occasionally. Seek Medical Aid. INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen

INGESTION: Give several glasses of milk or water. Vomiting may occur spontaneously, but it is not necessary to induce. Never give anything by mouth to an unconscious person.
Section 5 Fire Fighting Measures
Fire Extinguisher Type:Special powder or dry sand. Do not use water!
Fire/Explosion Hazards:Dust at sufficient concentrations can form explosive mixtures with air.
Fire Fighting Procedure:Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and clothing.
Section 6 Accidental Release Measures
Sweep up and place in suitable (fiberboard) containers for reclamation or later disposal.
Section 7 Handling and Storage
Store in a cool dry well ventilated area. Keep away from heat and flame. Do not get in eyes, on skin, or on clothing. 
Section 8 Exposure Controls & Personal Protection
Respiratory Protection:NIOSH approved dust mask
Ventilation: Mechanical: Hand Protection:Gloves to prevent skin exposure as latex or vinyl
Local Exhaust: Eye Protection:Splash Goggles
Other Protective Equipment: Wear appropriate clothing to prevent skin exposure

Section 11 Additional Information
Effects of overexposure, Acute and Chronic: No effects expected to skin. May cause mechanical abraision to eyes. Prolonged inhalation of dust or fume may result in a benign pneumoconiosis, producing distinctive changes in the lungs with no apparent disability or complications. Conditions aggravated/target organs: Persons with pre-existing eye, skin or respiratory conditions may be more susceptible.
