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

EMERGENCY OVERVIEW
Very toxic to aquatic organisms. May cause harm to the unborn child.
Possible risk of impaired fertility.

Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. A single prolonged skin exposure is not
likely to result in the material being absorbed in harmful amounts.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
Inhalation of a mist of this material may cause respiratory tract
irritation. Material has a low vapor pressure, so exposure to vapor
is not likely. May cause central nervous system effects.
Chronic:
May cause adverse reproductive effects. Possible risk of harm to the
unborn child.

**** 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:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
Treat symptomatically and supportively.

**** 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Avoid breathing
vapors from heated material. Avoid contact with eyes, skin, and
clothing. Avoid breathing spray or mist.
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:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
