Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
Harmful if swallowed, inhaled or absorbed through skin. Causes irritation
to skin, eyes and respiratory tract.
ROUTE OF EXPOSURE, SIGNS AND SYMPTOMS
INHALATION
Toxic. Causes irritation to the respiratory tract and systemic poisoning
with symptoms paralleling ingestion.
EYE CONTACT
May cause irritation, redness and pain.
SKIN CONTACT
Causes irritation, redness and pain. May be absorbed through the skin
causing systemic poisoning; symptoms may parallel ingestion.
INGESTION
Toxic. Can irritate the mouth, esophagus, stomach, etc. Excessive amounts
affect the blood and blood vessels. Signs and symptoms of nitrite poisoning
include intense cyanosis, nausea, dizziness, vomiting, collapse, spasms of
abdominal pain, rapid heart beat, irregular breathing, coma, convulsions, and
death due to circulatory collapse. Estimated lethal dose 1 to 2 grams.
SUMMARY OF CHRONIC HAZARDS
Repeated exposure through any route may cause symptoms similar to acute
toxicity.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
Individuals with pre-existing or chronic diseases of the eyes, skin and
respiratory system may have increased susceptibility to excessive exposure.
=============================================================================
Section 4 -- FIRST AID MEASURES
-----------------------------------------------------------------------------
If INHALED: If overcome by exposure, remove victim to fresh air
immediately. Give oxygen or artificial respiration as
needed. Obtain emergency medical attention. Prompt
action is essential.
If on SKIN: Immediately wash with soap and water. Remove and wash
any contaminated clothing.
If in EYES: Immediately flush eyes with plenty of water for at least 15
minutes, lifting upper and lower eyelids occasionally. Get
medical attention if irritation persists.
If SWALLOWED: If swallowed, call a physician or poison control
immediately. Only induce vomiting at the instruction of a
physician. Never give anything by mouth to an unconscious
person.
=============================================================================
Section 5 -- FIRE FIGHTING MEASURES
-----------------------------------------------------------------------------
FLASH POINT LEL UEL
None N/D N/D
Note: Not combustible, but substance is a strong oxidizer and its heat of
reaction with reducing agents or combustibles may cause ignition. Increases
the flammability of any combustible material.
EXTINGUSING MEDIA
Non-combustible. Use agents appropriate for surrounding fires.
SPECIAL FIRE FIGHTING PROCEDURES: In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained breathing apparatus with full
facepiece operated in the pressure demand or other positive pressure mode.
Decomposition of sodium nitrite may leave a caustic residue.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Contact with oxidizable substances may
cause extremely violent combustion. May explode when heated to 537 C (1000 F)
or on severe impact or on contact with cyanides, ammonium salts, cellulose,
lithium, potassium plus ammonia, and sodium thiosulfate.
=============================================================================
Section 6 -- ACCIDENTAL RELEASE MEASURES
-----------------------------------------------------------------------------
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Sweep up excess
material to prevent footing hazard. Discard in trash.
=============================================================================
Section 7 -- HANDLING AND STORAGE
-----------------------------------------------------------------------------
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING: Keep in a tightly closed
container, stored in a cool, dry, ventilated area. Protect against physical
damage and moisture. Isolate from any source of heat or ignition. Avoid
storage on wood floors. Separate from incompatibles, combustibles, organic
or other readily oxidizable materials. Containers of this material may be
hazardous when empty since they retain product residues (dust, solids);
observe all warnings and precautions listed for the product.
OTHER PRECAUTIONS: Avoid prolonged or repeated contact with skin or clothing.
=============================================================================
Section 8 -- EXPOSURE CONTROLS/PERSONAL PROTECTION
-----------------------------------------------------------------------------
RESPIRATORY PROTECTION (SPECIFY TYPE): Normally none required. Use NIOSH/MSHA
approved particulate respirator for nuisance dust.
VENTILATION - LOCAL EXHAUST: Acceptable
SPECIAL: N/A
MECHANICAL (GENERAL): Acceptable
OTHER: N/A
PROTECTIVE GLOVES: Wear rubber gloves.
EYE PROTECTION: Safety glasses (ANSI Z-87.1 or equivalent)
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Coveralls recommended.
WORK/HYGIENIC PRACTICES: Where use can result in skin contact, wash exposed
areas thoroughly before eating, drinking, smoking, or leaving work area.
Launder contaminated clothing before reuse.

Section 10 -- STABILITY AND REACTIVITY
-----------------------------------------------------------------------------
STABILITY: This material is stable in closed containers at room temperature.
Material slowly oxidizes to sodium nitrate when exposed to air. Very
hygroscopic.
CONDITIONS TO AVOID: Heat, flame, ignition sources, shock, friction,
incompatibles.
INCOMPATIBILITY (MATERIALS TO AVOID): Reacts vigorously with reducing
materials and is incompatible with many substances including ammonium salts,
cellulose, cyanides, lithium, potassium plus ammonia, sodium thiosulfate,
aminoguanide salts, butadiene, phthalic acid, phthalic anhydride, reducants,
sodium amide, sodium disulphite, sodium thiocyanate, urea, wood and organic
matter.
HAZARDOUS DECOMPOSITION PRODUCTS: Oxides of nitrogen.
HAZARDOUS POLYMERIZATION: Will not occur.
