3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Contact with combustible material may cause fire. Harmful if
swallowed. Irritating to eyes, respiratory system and skin.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If breathing becomes difficult,
call a physician.
AFTER SKIN CONTACT
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.
Call a physician.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician.
5 - Fire Fighting Measures
EXTINGUISHING MEDIA
Suitable: Carbon dioxide, dry chemical powder, or appropriate
foam.
SPECIAL RISKS
Specific Hazard(s): Emits toxic fumes under fire conditions.
Contact with other material may cause fire. May accelerate
combustion.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.
6 - Accidental Release Measures
PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP
Sweep up, place in a bag and hold for waste disposal. Avoid
raising dust. Ventilate area and wash spill site after material
pickup is complete.
7 - Handling and Storage
HANDLING
Directions for Safe Handling: Do not breathe dust. Do not get in
eyes, on skin, on clothing. Avoid prolonged or repeated exposure.
STORAGE
Conditions of Storage: Keep tightly closed. Keep away from
combustible materials, heat, sparks, and open flame.
8 - Exposure Controls / Personal Protection
ENGINEERING CONTROLS
Use only in a chemical fume hood. Safety shower and eye bath.
GENERAL HYGIENE MEASURES
Wash thoroughly after handling. Remove and wash contaminated
clothing promptly. Discard contaminated shoes.
PERSONAL PROTECTIVE EQUIPMENT

10 - Stability and Reactivity
STABILITY
Stable: Stable.
Conditions to Avoid: Mixtures of sodium nitrate with powdered
aluminum and an oxidant can result in a low-temperature exothermic
reaction at 705藲C in the presence of moisture. Interaction of
molten sodium nitrate and magnesium results in ignition. Mixing
sodium nitrate with sodium results in the formation of the
explosive sodium nitroxylate. A mixture of sodium nitrate, arsenic
trioxide, iron (II) sulfate spontaneously ignites. Sodium nitrate
in contact with jute, wood and cellulose materials will ignite
them at 240藲C but in the presence of up to 16% magnesium chloride
ignition occurs at 130藲C. Heating sodium nitrate with: sodium
phosphinate, sodium thiosulfate, sulfamates, powdered antimony,
boron phosphide, powdered charcoal, peroxyformic acid, barium
thiocyanate, metal cyanides results in explosions. When phenol was
added to trifluoroacetic acid/sodium nitrate, a hazardous rapid
exothermic reaction occurred
Materials to Avoid: Strong reducing agents, Finely powdered
metals, Strong acids, Organic materials.
HAZARDOUS DECOMPOSITION PRODUCTS
Hazardous Decomposition Products: Nitrogen oxides.
HAZARDOUS POLYMERIZATION
Hazardous Polymerization: Will not occur
