Symbols: XN O
Risk Phrases: 22 8
Section 3 - Hazards
Appearance: colourless. Danger! Hygroscopic. May cause eye
and skin irritation. May cause respiratory and digestive tract irritation. May
cause methemoglobinemia. Strong oxidizer. Contact with other material may cause
a fire. May be harmful if swallowed.
Target Organs: Blood,
blood forming organs.
Eye: May cause eye irritation.
Skin: May cause skin irritation.
Ingestion: May cause irritation of the digestive tract. May
be harmful if swallowed. Ingestion may produce eye disturbances, deafness,
speechlessness, and tetanic convulsions.
cause respiratory tract irritation. May cause methemoglobinemia, cyanosis,
convulsions, tachycardia, dyspnea (labored breathing), and death. The toxicity
of Nitrates is due to their in-vivo conversion to Nitrite s which may lead to
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.
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.
Ingestion: If victim is
conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid
immediately. Induce vomiting by giving one teaspoon of Syrup of Ipecac.
Inhalation: Remove from exposure to fresh air immediately.
If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical aid.
Notes to Physician: For
methemoglobinemia, administer oxygen alone or with Methylene blue depending on
the methemoglobinemia concentration in the blood.
Methylene blue, alone or in combination with oxygen is indicated as a treatment
in nitrite induced methemoglobinemia.
Section 5 - Fire
Information: As in any fire, wear a self-contained breathing apparatus
in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective
gear. 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
Extinguishing 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 area with water from a distance.
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. Provide ventilation.
Section 7 - Handling
Handling: Wash thoroughly after handling. Use with
adequate ventilation. Minimize dust generation and accumulation. Avoid contact
with skin and eyes. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Keep container tightly closed. Avoid contact with
clothing and other combustible materials. Avoid ingestion and inhalation. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers
to heat, sparks or open flames.
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.
Section 8 - Exposure
Controls, Personal Protection
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.
OSHA Vacated PELs: Sodium
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 protective gloves to prevent skin
Clothing: Wear appropriate protective clothing to
prevent skin exposure.
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.
