Sodium Nitrate 7631-99-4 99 - 100% Yes
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. 
Inhalation: Remove to fresh air. Get medical 
attention for any breathing difficulty. 
Ingestion: 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. 
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. 
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8
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.
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 dust or mist is apparent and engineering controls are not feasible, 
a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil 
particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a 
NIOSH type R or P filter. 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. 
Appearance: White crystals. 
Odor: Odorless. 
Solubility: 81.5 g/100 g water @ 15C (59F) 
Specific Gravity: 2.26 
pH: Aqueous solution is neutral. 
% Volatiles by volume @ 21C (70F): 0 
Boiling Point: 380C (716F) 
Melting Point: 308C (586F) 
Vapor Density (Air=1): No information found. 
Vapor Pressure (mm Hg): No information found. 
Evaporation Rate (BuAc=1): No information found. 
Stability: Stable under ordinary conditions of use 
and storage. 
Hazardous Decomposition Products: Emits nitrous oxides when heated to 
decomposition. 
Hazardous Polymerization: Will not occur. 
Incompatibilities: Reacts with acids to emit toxic fumes of nitrogen 
dioxide. Contact with the following may cause an explosion: barium rhodanide, 
boron phosphide, cyanides, sodium thiosulfate, sodium hypophosphite, sulfur plus 
charcoal, powdered aluminum and aluminum oxide. Fibrous organic material such as 
jute, wood, and similar cellulosic materials can become highly combustible by 
nitrate impregnation. 
Conditions to Avoid: Heat, flame, ignition sources, shock, friction, 
incompatibles. 
Oral rat LD50: 1267 mg/kg. Investigated as a tumorigen, mutagen, reproductive effector.
