Potential Health Effects
----------------------------------

Inhalation:
Inhalation of large amounts of dust may cause
irritation to the respiratory tract.
Ingestion:
Extremely large
oral dosages may produce gastrointestinal disturbances.
Skin
Contact:
Possible irritation on prolonged contact with moist or
sensitive areas of the skin.
Eye Contact:
No adverse effects
expected but dust may cause mechanical irritation.
Chronic
Exposure:
No information found.
Aggravation of Pre-existing
Conditions:
No information found.

4. First Aid Measures

Inhalation:
Remove to fresh air. Get medical attention
for any breathing difficulty.
Ingestion:
Give several glasses
of water to drink to dilute. If large amounts were swallowed, get medical
advice.
Skin Contact:
Wash exposed area with soap and water.
Get medical advice if irritation develops.
Eye Contact:
Wash
thoroughly with running water. Get medical advice if irritation develops.

5. Fire Fighting Measures

Fire:
As with most organic solids, fire is possible at
elevated temperatures or by contact with an ignition source.

Explosion:
Fine dust dispersed in air in sufficient
concentrations, and in the presence of an ignition source is a potential dust
explosion hazard.
Fire Extinguishing Media:
Water spray, dry
chemical, alcohol foam, or carbon dioxide.
Special Information:

In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated in the
pressure demand or other positive pressure mode.

6. Accidental Release Measures

Remove all sources of ignition. Ventilate area of leak or spill.
Wear appropriate personal protective equipment as specified in Section 8.
Spills: Clean up spills in a manner that does not disperse dust into the air.
Use non-sparking tools and equipment. Reduce airborne dust and prevent
scattering by moistening with water. Pick up spill for recovery or disposal
and place in a closed container.

7. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. Isolate from incompatible
substances. Containers of this material may be hazardous when empty since they
retain product residues (dust, solids); observe all warnings and precautions
listed for the product.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
None established.

Ventilation System:
In general, dilution ventilation is a
satisfactory health hazard control for this substance. However, if conditions
of use create discomfort to the worker, a local exhaust system should be
considered.
Personal Respirators (NIOSH Approved):
For
conditions of use where exposure to dust or mist is apparent and engineering
controls are not feasible, a particulate respirator (NIOSH type N95 or better
filters) may be worn. If oil particles (e.g. lubricants, cutting fluids,
glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies
or instances where the exposure levels are not known, use a full-face
positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators
do not protect workers in oxygen-deficient atmospheres.
Skin
Protection:
Wear protective gloves and clean body-covering clothing.

Eye Protection:
Use chemical safety goggles. Maintain eye wash
fountain and quick-drench facilities in work area.
