EMERGENCY OVERVIEW
Not available.
Potential Health Effects
Eye:
Causes eye irritation. May cause conjunctivitis.
Skin:
Causes skin irritation. Chronic exposure has been linked with
rhinitis (inflammation of the mucous membrane of the nose),
nosebleeds, laryngitis, pharyngitis, lung membrane effects, and an
impaired sense of smell and taste.
Ingestion:
Ingestion of large amounts may cause gastrointestinal irritation.
Inhalation:
Dust is irritating to the respiratory tract.
Chronic:
Chronic exposure has been linked with rhinitis (inflammation of the
mucous membrane of the nose), nosebleeds, laryngitis, pharyngitis,
lung membrane effects, and an impaired sense of smell and taste.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists.

aid if cough or other symptoms appear.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use with adequate ventilation. Minimize dust generation and
accumulation. Avoid contact with skin and eyes. Avoid ingestion and
inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
