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

Inhalation:
Causes irritation to the respiratory tract.
Symptoms may include coughing, shortness of breath.
Ingestion:

Irritation of the mucous membranes due to hydrolysis and formation of acid
in the stomach can occur. Large amounts can produce stomach cramps, stricture
of the esophagus, nausea, and vomiting.
Skin Contact:
Causes
irritation to skin. Symptoms include redness, itching, and pain.
Eye
Contact:
Causes irritation, redness, and pain.
Chronic
Exposure:
No information found.
Aggravation of Pre-existing
Conditions:
Persons with pre-existing skin disorders or impaired
respiratory function may be more susceptible to the effects of the substance.

4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
Induce vomiting immediately as directed
by medical personnel. Never give anything by mouth to an unconscious person.
Get medical attention.
Skin Contact:
Immediately flush skin
with plenty of water for at least 15 minutes. Remove contaminated clothing and
shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean
shoes before reuse.
Eye Contact:
Immediately flush eyes with
plenty of water for at least 15 minutes, lifting lower and upper eyelids
occasionally. Get medical attention immediately.

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:
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

Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Pick up and place in a
suitable container for reclamation or disposal, using a method that does not
generate dust. US Regulations (CERCLA) require reporting spills and releases
to soil, water and air in excess of reportable quantities. The toll free
number for the US Coast Guard National Response Center is (800)
424-8802.

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:
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.
