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

EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. May
cause sensitization by skin contact. May cause cancer. Very toxic to
aquatic organisms, may cause long-term adverse effects in the aquatic
environment.

Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be absorbed through the skin in
harmful amounts. May cause skin sensitization, an allergic reaction,
which becomes evident upon re-exposure to this material.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
May cause respiratory tract irritation.
Chronic:
May cause liver and kidney damage.

**** 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
immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. 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 immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. 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. Dusts at sufficient concentrations can form
explosive mixtures with air. During a fire, irritating and highly
toxic gases may be generated by thermal decomposition or combustion.
Risk of explosion in the event of decomposition.
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:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.

**** 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. May form flammable dust-air mixtures.
Avoid contact with eyes, skin, and clothing. Keep container tightly
closed. 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:
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.
Exposure Limits
CAS# 5341-61-7:


Personal Protective Equipment
