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

EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed.
Irritating to eyes and skin. May cause sensitization by skin
contact. May cause cancer. Very toxic to aquatic organisms. Toxic :
danger of serious damage to health by prolonged exposure through
inhalation, contact with skin and if swallowed.Air sensitive.Light
sensitive.Cancer suspect agent.Possible risks of irreversible
effects.

Potential Health Effects
Eye:
Causes severe eye irritation. May cause retinal damage.
Skin:
Causes severe skin irritation. May be fatal if absorbed through the
skin. May cause skin sensitization, an allergic reaction, which
becomes evident upon re-exposure to this material. May cause
eczematous dermatitis with swelling and vesiculation.
Ingestion:
Harmful if swallowed. May cause kidney, liver and spleen damage. May
cause bone marrow damage. May cause systemic effects by ingestion:
blood hemolysis with or without anemia,
methemoglobinemia-carboxyhemoglobinemia, and pulmonary changes.
Causes digestive tract irritation with possible burns.
Inhalation:
Harmful if inhaled. May cause effects similar to those described for
ingestion. Causes severe respiratory tract irritation. Inhalation may
produce weakness, fatigue, dizziness, and vertigo. Acute exposure to
low concentrations of hydrazines may cause and produce bronchial
mucous destruction, pulmonary edema, cyanosis (bluish discoloration
of skin due to deficient oxygenation of the blood) and possible
death.
Chronic:
Possible cancer hazard based on tests with laboratory animals.
Prolonged or repeated skin contact may cause dermatitis. Prolonged or
repeated eye contact may cause conjunctivitis. Chronic inhalation and
ingestion may cause effects similar to those of acute inhalation and
ingestion. 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. May
cause fetal effects. Laboratory experiments have resulted in
mutagenic effects.

**** 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. Wash clothing before reuse.
Ingestion:
Do not induce vomiting. 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 immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. 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:
For methemoglobinemia, administer oxygen alone or with Methylene
Blue depending on the methemoglobin concentration in the blood.
Monitor arterial blood gases, chest x-ray, pulmonary function tests
if respiratory tract irritation or respiratory depression is evident.
Monitor methemoglobin and blood sugar levels. Effects may be
delayed.

**** 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. Water runoff can cause environmental damage. Dike
and collect water used to fight fire. During a fire, irritating and
highly toxic gases may be generated by thermal decomposition or
combustion. Use water spray to keep fire-exposed containers cool.
Combustible liquid. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas. Contact with
metals may evolve flammable hydrogen gas. Containers may explode
when heated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use agent most
appropriate to extinguish fire. Do NOT get water inside containers.
For small fires, use dry chemical, carbon dioxide, or water spray.
For large fires, use dry chemical, carbon dioxide, alcohol-resistant
foam, or water spray. Cool containers with flooding quantities of
water until well after fire is out.

**** 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. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation.
Place under an inert atmosphere. Do not get water inside containers.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Keep away from heat,
sparks and flame. Do not ingest or inhale. Store protected from
light. Handle under an inert atmosphere. Store protected from air.
Use only in a chemical fume hood. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not expose
to air. Store protected from light. Store under an inert atmosphere.

**** 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 only under a
chemical fume hood.
