PRODUCT IDENTIFICATION
-------------------------------------------------------------------------------
SEE DATA PAGES FOR ADDITIONAL INFORMATION.
PRODUCT: SODIUM NITRITE.
SYNONYMS: Nitrous acid, sodium salt.
HAZARDOUS INGREDIENTS: Sodium nitrite.
EMERGENCY PHONE NUMBER: 314-982-5000.
PRECAUTIONARY MEASURES
-------------------------------------------------------------------------------
DANGER! STRONG OXIDIZER. CONTACT WITH OTHER
MATERIAL MAY CAUSE FIRE.
HEAT, SHOCK, OR CONTACT WITH OTHER MATERIAL MAY CAUSE FIRE OR EXPLOSIVE
DECOMPOSITION. HARMFUL IF SWALLOWED, INHALED OR ABSORBED THROUGH SKIN
CAUSES IRRITATION.
Keep from contact with clothing and other combustible materials.
Store in a tightly closed container.
Remove and wash contaminated clothing promptly.
Keep away from heat and flame.
Avoid breathing dust.
Keep container closed.
Use with adequate ventilation.
Wash thoroughly after handling.
EMERGENCY/FIRST AID
-------------------------------------------------------------------------------
SEE DATA PAGES FOR ADDITIONAL INFORMATION.
If swallowed, induce vomiting immediately by giving two glasses of water
and sticking finger down throat. Never give anything by mouth to an
unconscious person. If inhaled, remove to fresh air. If not
breathing,
give artificial respiration. If breathing is difficult, give oxygen.
In
case of contact, immediately flush skin or eyes with plenty of water for
at least 15 minutes. In all cases call a physician.
SEE HEALTH HAZARD INFORMATION SECTION.

FIRE AND EXPLOSION INFORMATION
-------------------------------------------------------------------------------
FIRE: 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.
EXPLOSION: Contact with oxidizable substances may cause extremely violent
combustion. May explode when heated to 537 deg. C. (1000 deg. F.) or on
severe impact or on contact with cyanides, ammonium salts, cellulose,
lithium, potassium plus ammonia, and sodium thiosulfate.
FIRE EXTINGUISHING MEDIA: Water or water spray in early stages of fire.
Foam or dry chemical may also be used. Water streams may scatter molten
material.
SPECIAL INFORMATION: 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.
REACTIVITY DATA
-------------------------------------------------------------------------------
STABILITY: This material is stable in closed containers at room
temperature.
Material slowly oxidizes to sodium nitrate when exposed to air.
Very hygroscopic.
HAZARDOUS DECOMPOSITION PRODUCTS: Oxides of nitrogen.
HAZARDOUS POLYMERIZATION: This substance does not polymerize.
INCOMPATIBILITIES: 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.
LEAK/SPILL DISPOSAL INFORMATION
-------------------------------------------------------------------------------
Ventilate area of leak or spill. Clean-up personnel require protective
clothing and respiratory protection from dust.
SPILLS: Pick up and place in a suitable container for reclamation or
disposal in a method that does not generate dust.
DISPOSAL: Whatever cannot be saved for reclamation may be disposed in a
RCRA approved hazardous waste facility.
REPORTABLE QUANTITY (RQ)(CWA/CERCLA): 100 lbs.
Ensure compliance with local, state and federal regulations.

HEALTH HAZARD INFORMATION
-------------------------------------------------------------------------------
EXPOSURE/HEALTH EFFECTS:
INHALATION: May cause irritation to the respiratory tract and
systemic
poisoning with symptoms paralleling ingestion.
INGESTION: May cause headache, flushing of the skin, vomiting, colic
and
diarrhea, muscular weakness, dizziness, collapse, fall in blood pressure,
cyanosis, convulsions, coma, respiratory paralysis, and death due to
circulatory collapse. Estimated lethal dose 1 to 2 grams.
SKIN CONTACT: May cause irritation, redness and pain. May be
absorbed
through the skin causing systemic poisoning; symptoms may parallel ingestion.
EYE CONTACT: May cause irritation, redness, and pain.
CHRONIC EXPOSURE: Repeated exposure through any route may cause
symptoms
similar to acute toxicity.
AGGREVATION OF PRE-EXISTING CONDITIONS: No information found.
FIRST AID:
INHALATION: Remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Call a
physician.
INGESTION: If swallowed, induce vomiting immediately by giving two
glasses of water and sticking finger down throat. Never give anything
by mouth to an unconscious person. Call physician immediaely.
SKIN EXPOSURE: In case of contact, immediately flush skin with plenty
of water for at least 15 minutes while removing contaminated clothing and
shoes. Call a physician.
EYE EXPOSURE: Wash eyes with plenty of water for at least 15
minutes,
lifting lower and upper eyelids occasionally. Get medical attention
immediately.
TOXICITY DATA (RTECS, 1991): Oral (rat) LD50: 85 mg/kg
Irritation: eye
(rabbit): 500 mg/24H mild substance investigated as: mutagen and
reproductive effector.
OCCUPATIONAL
CONTROL MEASURES
-------------------------------------------------------------------------------
AIRBORNE EXPOSURE LIMITS: None established.
VENTILATION SYSTEM: A local exhaust system which captures the contaminant
at its source is recommended to prevent dispersion of the contaminant into
the workroom air.
PERSONAL RESPIRATORS (NIOSH APPROVED): A supplied air, full facepiece
respirator, air-lined hood, or self-contained breathing apparatus is
recommended.

SKIN PROTECTION: Wear impervious protective clothing, including boots,
gloves, lab coat, apron or coveralls to prevent skin contact.
EYE PROTECTION: Use chemical safety goggles and/or full face shield where
dusting or splashing of solutions is possible. Contact lenses should not
be
worn when working with this material. Maintain eye wash fountain and
quick-drench facilities in work area.
STORAGE
AND SPECIAL INFORMATION
-------------------------------------------------------------------------------
Keep in a tightly closed container. Store in a cool, dry, ventilated
area away from sources of heat or ignition. Separate from combustible,
organic or any other readily oxidizable materials. Protect container from
physical damage. Isolate from incompatible substances. Do not store
on
wooden floors.
