Composition, Information on Ingredients
||Nitric acid potassium salt
Risk Phrases: 8
Section 3 - Hazards
Appearance: white. Danger! Strong oxidizer. Contact with
other material may cause a fire. May cause respiratory tract irritation. May
cause eye and skin irritation. May cause digestive tract irritation with nausea,
vomiting, and diarrhea. May cause methemoglobinemia. May cause kidney damage.
May cause blood abnormalities.
Target Organs: Blood,
Potential Health Effects
Eye: May cause eye irritation.
Skin: Dust causes mechanical irritation. Low hazard for
usual industrial handling.
gastrointestinal irritation with nausea, vomiting and diarrhea.
Inhalation: May cause respiratory tract irritation. May
cause methemoglobinemia, cyanosis, convulsions, tachycardia, dyspnea (labored
breathing), and death.
Chronic: 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. May cause
kidney injury. 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.
Section 4 - First Aid
Eyes: Flush eyes with plenty of water for at least
15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin: Flush skin with plenty of soap and water for at least
15 minutes while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. 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.
from exposure to fresh air immediately. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.
Section 5 - Fire
Information: Strong oxidizer. Contact with combustible materials may
cause a fire. During a fire, irritating and highly toxic gases may be generated
by thermal decomposition or combustion. Wear appropriate protective clothing to
prevent contact with skin and eyes. Wear a self-contained breathing apparatus
(SCBA) to prevent contact with thermal decomposition products. Containers may
explode in the heat of a fire. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas. May decompose explosively
when heated or involved in a fire. May accelerate burning if involved in a fire.
May explode from heat or contamination.
Media: Cool containers with flooding quantities of water until well
after fire is out. 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
Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
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. Remove all sources of ignition. Provide ventilation. Do not use
combustible materials such as paper towels to clean up spill.
Section 7 - Handling
Handling: Wash thoroughly after handling. Avoid
prolonged or repeated contact with skin. Avoid contact with eyes. Keep container
tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation.
Wash clothing before reuse. Keep away from clothing and other combustible
Storage: Do not store near combustible
materials. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away from reducing

Controls, Personal Protection
Controls: Use adequate ventilation to keep airborne concentrations low.
