Composition, Information on Ingredients
Symbols: XI O
Risk Phrases: 36/37/38 8
Section 3 - Hazards
Appearance: white to gray to brown. Danger! Strong
oxidizer. Contact with other material may cause a fire. May cause eye and skin
irritation. May cause methemoglobinemia. Causes respiratory tract irritation.
Target Organs: Red blood cells.
Potential Health Effects
Eye: Causes eye irritation.
Skin: May cause skin irritation.
Ingestion: Ingestion of large amounts may cause
gastrointestinal irritation. Methemoglobinemia is characterized by dizziness,
drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart
rate and chocolate-brown colored blood.
cause methemoglobinemia, cyanosis, 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.
Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath
shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown
blood. Inhalation can cause systemic acidosis and methemoglobinemia.
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. May cause digestive tract
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: Get medical aid. Flush skin with plenty of soap and
water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: 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.
Inhalation: Remove from exposure to fresh
air immediately. If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Get medical aid.
Physician: Absorption of this product into the body may cause cyanosis
(bluish discoloration of skin due to deficient oxygenation of the blood).
Moderate degrees of cyanosis need to be treated only by supportive measures: bed
rest and oxygen inhalation. For methemoglobinemia, administer oxygen alone or
with Methylene blue depending on the methemoglobinemia concentration in the
blood. Cleansing of the entire contaminated area of the body is of utmost
Section 5 - Fire
Information: Strong oxidizer. Contact with combustible materials may
cause a fire. 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. May explode under confinement and high
temperatures, especially if contaminated.
Media: Use water spray to cool fire-exposed containers. Use flooding
quantities of water.
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.
Section 7 - Handling
Handling: Use with adequate ventilation. Minimize
dust generation and accumulation. Avoid contact with eyes, skin, and clothing.
Empty containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Avoid contact with heat, sparks and
flame. Avoid contact with clothing and other combustible materials. Avoid
ingestion and inhalation. Keep away from clothing and other combustible
materials. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames.
Keep away from sources of ignition. 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 acids. Keep away from reducing
agents. Do not store near alkaline substances.
Section 8 - Exposure
Controls, Personal Protection
Controls: Use adequate ventilation to keep airborne concentrations low.
OSHA Vacated PELs: Ammonium
nitrate: No OSHA Vacated PELs are listed for this chemical.
Eyes: Wear appropriate
protective eyeglasses or chemical safety goggles as described by OSHA's eye and
face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin: Wear appropriate gloves to prevent skin exposure.
Clothing: Wear appropriate protective clothing to minimize
contact with skin.
Respirators: Follow the OSHA respirator
regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator when necessary.
