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

EMERGENCY OVERVIEW
Harmful by inhalation, in contact with skin and if swallowed. Very
toxic by inhalation, in contact with skin and if swallowed. Danger of
cumulative effects.

Potential Health Effects
Eye:
Causes severe eye irritation.
Skin:
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. If absorbed, may cause symptoms
similar to those for ingestion.
Ingestion:
May cause irritation of the digestive tract. May cause kidney
damage. May cause methemoglobinemia, cyanosis (bluish discoloration
of skin due to deficient oxygenation of the blood), convulsions, and
death. Methemoglobinemia is characterized by dizziness, drowsiness,
headache, shortness of breath, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), rapid heart rate and
chocolate-brown colored blood.
Inhalation:
May cause severe allergic respiratory reaction. May cause
respiratory tract irritation.
Chronic:
May cause cancer according to animal studies.

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

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Immediately flush
eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
symptoms occur.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Get medical aid immediately. Do NOT induce vomiting. If conscious and
alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant 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. Sweep up,
then place into a suitable container for disposal.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Avoid contact
with eyes, skin, and clothing. Do not get on skin or in eyes. Avoid
ingestion and inhalation. Do not ingest or inhale.
Storage:
Store in a cool, dry place. Keep container closed when not in use.
Store in a tightly closed container.

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

Engineering Controls:
Use adequate ventilation to keep airborne concentrations low. Use
adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits. Use process
enclosure, local exhaust ventilation, or other engineering controls
to control airborne levels.
Exposure Limits
CAS# 20265-97-8:


Personal Protective Equipment

Eyes:
Wear safety glasses and chemical goggles if splashing
is possible. Wear appropriate protective eyeglasses or
chemical safety goggles as described by OSHA's eye and
face protection regulations in 29 CFR 1910.133 or
European Standard EN166.
Skin:
Wear appropriate protective gloves and clothing to
prevent skin exposure. Wear appropriate gloves to
prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Wear a NIOSH/MSHA or European Standard EN 149
approved full-facepiece airline respirator in the
positive pressure mode with emergency escape
provisions. Follow the OSHA respirator regulations
found in 29 CFR 1910.134 or European Standard EN 149.
Use a NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
