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

EMERGENCY OVERVIEW
Risk of serious damage to eyes. Contact with combustible material
may cause fire.The toxicological properties of this material have
not been fully investigated.Hygroscopic (absorbs moisture from the
air).

Potential Health Effects
Eye:
May cause eye irritation. Dust may cause mechanical irritation.
The toxicological properties of this material have not been fully
investigated.
Skin:
May cause skin irritation. The toxicological properties of this
material have not been fully investigated.
Ingestion:
May cause methemoglobinemia, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), convulsions, and death.
May cause digestive tract disturbances. The toxicological properties
of this substance have not been fully investigated. Expected to be a
low ingestion hazard. 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 respiratory tract irritation. The toxicological properties
of this substance have not been fully investigated.
Chronic:
No information found.

**** 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.
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:
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. Wash mouth out with 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.
Notes to Physician:
Antidote:
None reported.

**** 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. Strong oxidizer. Contact with other material may
cause fire. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion.
Extinguishing Media:
Use water only! Use water spray, dry chemical, carbon dioxide, or
chemical foam. Contact professional fire-fighters immediately.

**** 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. Avoid
generating dusty conditions. Remove all sources of ignition. Provide
ventilation.

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

Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Use with adequate ventilation. Minimize dust generation and
accumulation. Avoid breathing dust, vapor, mist, or gas. Avoid
contact with eyes, skin, and clothing. Avoid contact with skin and
eyes. Keep container tightly closed. Avoid contact with clothing and
other combustible materials. Avoid ingestion and inhalation. Use only
in a chemical fume hood.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. 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# 52788-53-1:


Personal Protective Equipment

Eyes:
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 to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
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.
