Section 3 - Hazards Identification
EMERGENCY OVERVIEW
Appearance: yellow solid.
Danger! May be fatal if absorbed through the skin. Causes eye, skin, and
respiratory tract irritation. May cause allergic skin reaction. May cause
methemoglobinemia. May cause cardiac disturbances. May cause central nervous
system effects. Heat sensitive. Marine pollutant.
Target Organs: Blood, central nervous system, cardiovascular system, blood
forming organs, skin.
Potential Health Effects
Eye: May cause eye irritation and possible damage.
Skin: May be fatal if absorbed through the skin. Prolonged and/or repeated contact
may cause irritation and/or dermatitis. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion: Causes gastrointestinal irritation with nausea, vomiting and diarrhea.
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.
Inhalation: May cause methemoglobinemia, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), convulsions, tachycardia, dyspnea
(labored breathing), and death. May cause severe irritation of the respiratory tract
with sore throat, coughing, shortness of breath and delayed lung edema. May cause
cardiac abnormalities. Inhalation at high concentrations may cause CNS depression
and asphixiation.
Chronic: Prolonged or repeated skin contact may cause sensitization dermatitis and
possible destruction and/or ulceration. Prolonged exposure may cause anemia and
methemoglobinemia, characterized by dizziness, drowsiness, headache, breath
shortness, cyanosis (bluish skin due to deficient oxygenation of the blood), rapid
heart rate and chocolate-brown colored blood. Repeated exposure may cause allergic
respiratory reaction (asthma). Typically the retrobulbar (behind the eyeball) neuritis
resulting from chronic poisoning has been associated with peripheral neuritis
manifest as paresthesias (burning, prickling sensations in absence of an external
stimulus) and pains in the legs and burning of the
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 imme diately.
Skin: In case of contact, immediately flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Get medical aid
immediately. Wash clothing before reuse.
Ingestion: If swallowed, do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. Get medical aid.
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.
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. Runoff from fire
control or dilution water may cause pollution.
Extinguishing Media: Water or foam may cause frothing. 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: 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. Remove contaminated clothing and wash
before reuse. Minimize dust generation and accumulation. Do not get in eyes, on
skin, or on clothing. Do not ingest or inhale. Use only with adequate ventilation.
Storage: Store in a tightly closed container. Keep from contact with oxidizing
materials. Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep away from flammable liquids. Do not store near alkaline
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.
