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

EMERGENCY OVERVIEW
Contact with combustible material may cause fire.

Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause methemoglobinemia, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), convulsions, and death.
May cause nausea, vomiting, and diarrhea, possibly with blood.
Inhalation:
May cause respiratory tract irritation. May cause methemoglobinemia,
cyanosis (bluish discoloration of skin due to deficient oxygenation
of the blood), convulsions, tachycardia, dyspnea (labored breathing),
and death. May cause effects similar to those described for
ingestion.
Chronic:
May cause methemoglobinemia, which is characterized by
chocolate-brown colored blood, headache, weakness, dizziness, breath
shortness, cyanosis (bluish skin due to deficient oxygenation of
blood), rapid heart rate, unconsciousness and possible death.
Repeated exposure may cause kidney damage and digestive tract
abnormalities. Effects may be delayed.

**** 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.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or 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. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
Treat symptomatically and supportively.
Antidote:
The use of Calcium disodium EDTA as a chelating agent should be
determined by qualified medical personnel.

**** 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. Use water with
caution and in flooding amounts. Some oxidizers may react explosively
with hydrocarbons(fuel). May accelerate burning if involved in a
fire. Containers may explode when heated.
Extinguishing Media:
Use water only! Contact professional fire-fighters immediately. For
small fires, do NOT use dry chemicals, carbon dioxide, halon or
foams. USE WATER ONLY. For large fires flood fire with water from a
distance.

**** 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. Remove all sources of ignition. Provide ventilation. Do not
use combustible materials such as paper towels to clean up spill.

**** 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. Keep container tightly closed.
Avoid contact with clothing and other combustible materials. Avoid
ingestion and inhalation. Use with adequate ventilation.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. 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

exposure.
Clothing:
Wear a chemical apron. Wear appropriate protective
clothing to prevent skin exposure.
