4. HEALTH HAZARD DATA:
PRIMARY ROUTE(S) OF ENTRY:
INHALATION? YES SKIN? YES INGESTION? YES
OSHA REGULATED? NO
CARCINOGENICITY: NTP? NO IARC? NO
ACUTE EFFECT OF OVEREXPOSURE:
EYES: MAY CAUSE IRRITATION, SYMPTOMS INCLUDING REDNESS,
ITCHING AND PAIN.
SKIN: MAY CAUSE IRRITATION, SYMPTOMS INCLUDING REDNESS,
ITCHING AND PAIN.
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.
CHRONIC EFFECTS OF 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.
TOXICITY DATA: ORAL RAT LD50: 1267 MG/KG. INVESTIGATED AS A
TUMORIGEN, MUTAGEN, REPRODUCTIVE EFFECTOR.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: WORKERS WITH A HISTORY OF
KIDNEY OR LUNG DISEASE MAY BE MORE SUSCEPTIBLE TO THE EFFECTS OF THIS
SUBSTANCE.
EMERGENCY AND FIRST AID PROCEDURES:
EYE CONTACT: WASH EYES WITH COPIOUS AMOUNTS OF WATER FOR AT
LEAST 15 MINUTES, LIFTING LOWER AND UPPER EYELIDS
OCCASIONALLY. GET MEDICAL ATTENTION IMMEDIATELY.
SKIN CONTACT: REMOVE ANY CONTAMINATED CLOTHING. WIPE OFF
EXCESS FROM SKIN. WASH SKIN WITH SOAP AND WATER
MSDS: SODIUM NITRATE Page 4 of 5
*********************************************************************
4. HEALTH HAZARD DATA (CONT):
FOR AT LEAST 15 MINUTES. GET MEDICAL ATTENTION
IF IRRITATION DEVELOPS OR PERSISTS.
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.
5. FIRE AND EXPLOSION HAZARD DATA:
FLASH POINT (METHOD USED): NA
FLAMMABLE LIMITS: NA LEL NA UEL NA
EXTINGUISHING MEDIA: USE ANY MEANS SUITABLE FOR EXTINGUISHING
SURROUNDING FIRE. WATER SPRAY MAY BE USED TO KEEP FIRE EXPOSED
CONTAINERS COOLED.
SPECIAL FIRE FIGHTING PROCEDURES: 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.
UNUSUAL FIRE AND EXPLOSION HAZARDS: NOT COMBUSTIBLE, BUT SUBSTANCE
IS A STRONG OXIDIZER AND ITS HEAT OF REACTION WITH REDUCING AGENTS OR
COMBUSTIBLE MAY CAUSE IGNITION. EXPLOSIVE WITH SHOCK, HEAT OR
FRICTION. SODIUM NITRATE DECOMPOSES EXPLOSIVELY WHEN HEATED > 538掳C
(1000掳F)
6. REACTIVITY DATA:
STABILITY: UNSTABLE: STABLE: X
INCOMPATIBILITY (MATERIALS TO AVOID): REACTS WITH ACIDS TO EMIT
TOXIC FUMES OF NITROGEN DIOXIDE. CONTACT WITH THE FOLLOWING MAY
CAUSE AN EXPLOSION: BARIUM RHODANIDE, BORON PHOSPHIDE, CYANIDES,
SODIUM THIOSULPHATE, 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.
HAZARDOUS DECOMPOSITION OF BY-PRODUCTS: EMITS NITROUS OXIDES WHEN
HEATED TO DECOMPOSITION.
HAZARDOUS POLYMERIZATION:
MAY OCCUR: WILL NOT OCCUR: X
MSDS: SODIUM NITRATE Page 5 of 5
*********************************************************************
7. SPILL OR LEAK PROCEDURES:
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: CLEAN UP
SPILLS IN A MANNER THAT DOES NOT DISPENSE 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.
WASTE DISPOSAL METHODS: OBSERVE ALL FEDERAL, STATE AND LOCAL
REGULATIONS.
8. SPECIAL PROTECTION INFORMATION:
RESPIRATORY PROTECTION (SPECIFY TYPE): 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.
VENTILATION: LOCAL EXHAUST: X MECHANICAL:
OTHER:
PROTECTIVE GLOVES: RUBBER OR NEOPRENE
EYE PROTECTION: CHEMICAL SAFETY GOGGLES AND/OR FULL FACE SHIELD
WHERE DUSTING OR SPLASHING OF SOLUTIONS IS POSSIBLE.
OTHER PROTECTIVE EQUIPMENT: IMPERVIOUS BOOTS, APRON OR COVERALLS, AS
NEEDED IN AREAS OF UNUSUAL EXPOSURE.
9. SPECIAL PRECAUTIONS:
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: KEEP IN TIGHTLY
CLOSED CONTAINER, STORED IN A COOL, DRY VENTILATED AREA. PROTECT
AGAINST PHYSICAL DAMAGE. SEPARATE FROM COMBUSTIBLES, ORGANIC OR
OTHER READILY OXIDIZABLE MATERIALS.
OTHER PRECAUTIONS: NIF
10. OTHER INFORMATION:
NONE
