EMERGENCY OVERVIEW
Appearance: beige brown solid.
May be fatal if swallowed. Danger! May cause
respiratory tract irritation. May cause eye and skin irritation. May
cause blood abnormalities. May cause lung damage. May cause liver
and kidney damage. May cause cardiac disturbances. May cause central
nervous system effects. May cause methemoglobinemia.
Target Organs: Blood, kidneys, central nervous
system, liver, lungs, cardiovascular system, blood forming organs.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May be fatal if swallowed. May cause irritation of the digestive
tract. May cause liver and kidney damage. May cause cardiac
disturbances. May cause methemoglobinemia, cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood),
convulsions, and death. May cause central nervous system effects. May
cause blood abnormalities.
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 liver and kidney damage. Central nervous system
effects may include confusion, ataxia (failure of muscular
coordination), vertigo, tinnitus, weakness, disorientation, lethargy,
drowsiness, and finally coma. May cause blood changes. May cause
cardiac abnormalities.
Chronic:
May cause liver and kidney damage. 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. 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. 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 immediately. SPEED IS ESSENTIAL. A DOCTOR MUST BE NOTIFIED AT
ONCE. 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 breathing
is difficult, give oxygen. Get medical aid. 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.
Antidote:
Methylene blue, alone or in combination with oxygen is indicated as
a treatment in nitrite induced methemoglobinemia.

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. Containers
may explode when heated. Combustible material; may burn but does not
ignite readily. Runoff from fire control or dilution water may cause
pollution.
Extinguishing Media:
Use water spray to cool fire-exposed containers. 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.
Flash Point: Not applicable.
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 3; Flammability: 1; Instability: 0
|
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Keep container tightly closed. Avoid ingestion
and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Poison room
locked.
|
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.
