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

Information on the human health effects from exposure to this
substance is limited.

Inhalation:
Not expected to be a
health hazard.
Ingestion:
No adverse effects expected.

Skin Contact:
Not expected to be a health hazard from skin
exposure.
Eye Contact:
Not expected to be a health hazard.

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:
If large amounts were
swallowed, give water to drink and 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:
Not considered to be a fire hazard.

Explosion:
Not considered to be an explosion hazard.

Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special Information:
Use
protective clothing and breathing equipment appropriate for the surrounding
fire.

6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Sweep up and
containerize for reclamation or disposal. Vacuuming or wet sweeping may be
used to avoid dust dispersal.

7. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. 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):
Not expected
to require personal respirator usage. 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:
Safety
glasses. Maintain eye wash fountain and quick-drench facilities in work area.
