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

EMERGENCY OVERVIEW
Irritating to eyes and skin. Very toxic to aquatic organisms, may
cause long-term adverse effects in the aquatic environment.Light
sensitive.

Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause digestive tract disturbances. Ingestion of large amounts
may cause CNS depression. Ingestion of large amounts may cause pain,
constipation or diarrhea.
Inhalation:
May cause respiratory tract irritation.
Chronic:
Prolonged or repeated exposure can cause psychic abnormalities such
as anxiety, depression and excitability.

**** 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. If irritation
develops, get medical aid.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Wash clothing before
reuse. Get medical aid if symptoms occur.
Ingestion:
Never give anything by mouth to an unconscious person. Do NOT induce
vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls
of milk or water. Get medical aid if irritation or symptoms occur.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Runoff from
fire control or dilution water may cause pollution.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam. Use agent most appropriate to extinguish
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. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Avoid
contact with eyes, skin, and clothing. Avoid ingestion and
inhalation. Store protected from light.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store
protected from light.

**** 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.
Exposure Limits
CAS# 118-75-2:


Personal Protective Equipment
