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

Inhalation:
Not expected to be a health hazard.

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

Eye Contact:
No adverse effects expected.
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:
When heated above 160C (320F) in enclosed spaces
may generate highly flammable/explosive acetone.
Explosion:
Not
considered to be an explosion hazard, except when heated (See above).

Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
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. Water spray may be used to
keep fire exposed containers cool.

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

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. Keep in a tightly closed container, stored in a cool,
dry, ventilated area. Protect against physical damage.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
None established.

Ventilation System:
A system of local and/or general exhaust is
recommended to keep employee exposures as low as possible. Local exhaust
ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work
area. Please refer to the ACGIH document, Industrial Ventilation, A Manual
of Recommended Practices, most recent edition, for details.

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.
