Potential Health Effects
----------------------------------
Inhalation:
Inhalation of dust irritates the respiratory tract. Symptoms may include coughing,
shortness of breath.
Ingestion:
May cause gastroenteritis and abdominal pains. Other symptoms may include dizziness,
bloody diarrhea, convulsions, and collapse. Purging and diuresis can be expected. Small
repeated doses may cause headache and mental impairment. Rare cases of nitrates being
converted to the more toxic nitrites have been reported, mostly with infants.
Skin Contact:
May cause irritation, symptoms including redness, itching, and pain.
Eye Contact:
May cause irritation, symptoms including redness, itching, and pain.
Chronic Exposure:
Under some circumstances methemoglobinemia occurs in individuals when the nitrate is
converted by bacteria in the stomach to nitrite. Nausea, vomiting, dizziness, rapid heart
beat, irregular breathing, convulsions, coma, and death can occur should this conversion
take place.
Aggravation of Pre-existing Conditions:
Workers with a history of kidney or lung disease may be more susceptible to the effects of
this substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
http://www.jtbaker.com/msds/s4442.htm 1/1/99
SODIUM NITRATE Page 3 of 8
Induce vomiting immediately as directed by medical personnel. Never give anything by
mouth to an unconscious person. Get medical attention.
Skin Contact:
Remove any contaminated clothing. Wipe off excess from skin. Wash skin with soap and
water for at least 15 minutes. Get medical attention if irritation develops or persists.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and
upper eyelids occasionally. Get medical attention immediately.
5. Fire Fighting Measures
Fire:
Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing
agents or combustibles may cause ignition.
Explosion:
Explosive with shock, heat or friction. Sodium Nitrate decomposes explosively when
heated > 538C (1000F). Sensitive to mechanical impact.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire. Water spray may be used to
keep fire exposed containers cool.
Special Information:
Wear full protective clothing and breathing equipment for high-intensity fire or potential
explosion conditions. This oxidizing material can increase the flammability of adjacent
combustible materials.
6. Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Clean up spills in a manner that
does not disperse dust into the air. Use non-sparking tools and equipment. Reduce
airborne dust and prevent scattering by moistening with water. Pick up spill for recovery
or disposal and place in a closed container. Small amounts of residue may be flushed to
sewer with plenty of water.
7. Handling and Storage
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

SODIUM NITRATE Page 4 of 8
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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as
low as possible. Local exhaust ventilation is generally preferred because it can control the
emissions of the contaminant at its source, preventing dispersion of it into the general
work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to the dust or mist is apparent, a half-face dust/mist
respirator may be worn. For emergencies or instances where the exposure levels are not
known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-
purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or
coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or splashing of solutions
is possible. Maintain eye wash fountain and quick-drench facilities in work area.
