**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes, respiratory system and
skin. May cause sensitization by inhalation and skin contact. Contact
with combustible material may cause fire.

Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause irritation of the digestive tract. May be harmful if
swallowed.
Inhalation:
Causes respiratory tract irritation. May cause allergic respiratory
reaction.
Chronic:
Repeated or prolonged exposure may cause allergic reactions in
sensitive individuals.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Immediately 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. Wash clothing before reuse.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid if cough or other symptoms
appear. Do NOT use mouth-to-mouth resuscitation. If breathing has
ceased apply artificial respiration using oxygen and a suitable
mechanical device such as a bag and a mask.
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. Strong oxidizer. Contact with other material may
cause fire.
Extinguishing Media:
Use water spray, dry chemical, or carbon dioxide. Cool containers
with flooding quantities of water until well after fire is out.

**** 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. Avoid generating dusty conditions. Provide ventilation.
Keep combustibles (wood, paper, oil, etc.,) away from spilled
material.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Keep container tightly closed. Avoid contact with clothing
and other combustible materials. Avoid ingestion and inhalation.
Storage:
Do not store near combustible materials. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from reducing agents. Store
protected from moisture.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
