**** 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.Corrosive.Carcinogen.

Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. May cause eye injury.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. May cause severe skin
irritation with possible burns, especially if skin is wet or moist.
Ingestion:
May cause liver and kidney damage. May cause severe digestive tract
irritation with abdominal pain, nausea, vomiting and diarrhea. May
cause corrosion and permanent tissue destruction of the esophagus and
digestive tract. Exposure may cause anemia and other blood
abnormalities. May be harmful if swallowed.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema. May
cause liver and kidney damage. May cause severe irritation of the
upper respiratory tract with pain, burns, and inflammation. May cause
effects similar to those described for ingestion.
Chronic:
Prolonged or repeated skin contact may cause sensitization
dermatitis and possible destruction and/or ulceration. May cause
liver and kidney damage. May cause cancer according to animal
studies. May cause digestive tract disturbances.

**** 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
immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
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. Combustion generates toxic fumes.
Extinguishing Media:
For small fires, use water spray, dry chemical, carbon dioxide or
chemical 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, then place into a suitable 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. Do not get on skin and clothing. Do not
ingest or inhale.
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 process enclosure,
local exhaust ventilation, or other engineering controls to control
airborne levels.
Exposure Limits
CAS# 10034-93-2:


Personal Protective Equipment
