LD50 LC50 Mixture:LD50: (ORAL, RAT)=85 MG/KG
Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:INHAL: DUST OR MIST OF SOLUTIONS MAY
IRRITATE RESP TRACT, IF INHALED, LG AMTS MAY CAUSE SYSTEMIC EFTS,
AS NITRITES ARE READILY ABSORBED BY LUNG TISS. INGEST: MAY IRRITATE
MOUTH, ESOPHAGUS, STOMACH, ET C. ALTHOUGH SM QTYS ARE USED IN FOOD
PREP (<100 PPM), LG AMTS OF SODIUM NITRITE CAN RSLT IN ACUTE (SEE
EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ: TOXIC EFTS: NAUS, CONVERSION OF
HEMOGLOBIN TO METHEMOGLOBIN PRODUCING CYANOSIS (BLUE SKIN) ; A
MARKED FALL IN BLOOD PRESSURE, LEADING TO COLLAPSE, COMA, POSSIBLY
DEATH.
Medical Cond Aggravated by Exposure:PREGNANCY .

First Aid:EYES: IMMED FLUSH W/WATER FOR AT LEAST 15 MIN, RAISE LIDS
OCCAS TO FACILITATE IRRIGATION. GET MD. SKIN: WASH W/SOAP & WATER,
THEN FLUSH W/WATER UNTIL ALL CHEM IS REMOVED. INHAL: REMOVE TO
FRESH AIR. I F BRTHG STOPPED, GIVE ARTF RESP, PREFERMOUTH-TO-MOUTH.
IF BRTHG DFCLT, GIVE WATER. GET MD. INGEST: IF CONSCIOUS, HAVE
VICTIM RINSE MOUTH, THEN IMMED GIVE 2-4 GLASSES WATER & INDUCE (SEE
SUPP DATA)

Flash Point:NONE
Extinguishing Media:FLOODING AMOUNTS OF WATER
Fire Fighting Procedures:NIOSH/MSHA APPROVED SCBA W/FULL FACEPIECE &
FULL PROT CLTHG. USE WATER SPRAY TO COOL FIRE-EXPOSED CNTNRS (IF OF
WATERPROOF CONST) OR TO DRENCH (SEE SUPP DATA)
Unusual Fire/Explosion Hazard:MATL IS AN OXIDIZING AGENT & CAN SUPPLY
O2 TO STIMULATE/ACCEL COMBUST OF ORG/OTHER COMBUST MATLS.
DECOMPOSES >320C, RELEASING TOXIC NITROGEN (SEE SUPP DATA)

Spill Release Procedures:IMMED SWEEP/SHOVEL SPILLED MATL INTO CLEAN
FIBER/STEEL DRUM; CLOSE & LABEL "OXIDIZER." REMOVE FLAMM MATLS OR
MONITOR CLEAN-UP OPS WITH A CO2 FIRE EXTING. FLUSH TRACE RESIDUES
W/WATER TO DILUTE & COMPL ETE CLEANUP. KEEP OUT OF SEWER.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:STORE IN A TIGHTLY CLOSED CNTNR IN A
COOL, DRY AREA AWAY FROM INCOMPAT MATLS. AVOID WOODEN FLOORS.
STORAGE IN AN ISOLATED NON-COMBUST (SEE INGRED 02)
Other Precautions:MATL DECOMPOSES EVEN BY WEAK ACIDS WITH EVOLUTION OF
BROWN FUMES OF N2O3. IT IS SLOWLY OXIDIZED TO SODIUM NITRATE WHEN
EXPOSED TO AIR. MAY BE FATAL IF DIRECTLY INGESTED (THE ADULT LETHAL
DOSE IS APPRO XIMATELY 2-5 GRAMS).

Respiratory Protection:USE NIOSH/MSHA APPROVED RESPIRATOR FOR PRODUCT
DUSTS OR SOLUTION MISTS--OR NITROGEN OXIDE GASES--AS APPLICABLE.
SOME EXPOSURES MAY REQUIRE NIOSH/MSHA APPROVED SCBA OR A SUPPLIED
AIR RESPIRATOR.
Ventilation:GENERAL VENT IN STOR & WORKPLACE AREAS. LOCAL EXHAUST IF
DUSTY/MISTY CONDITIONS PREVAIL--OR IF THEY ARE LIKELY TO OCCUR.
Protective Gloves:IMPERVIOUS GLOVES
Eye Protection:CHEMICAL WORKERS GOGGLES
Other Protective Equipment:HARD HAT/OTHER HEAD COVER, IMPERVIOUS APRON,
FULL WORK/IMPERVIOUS CLTHG. EYE WASH STA & WASHING FACS NEAR
USE/HNDLG AREA
Work Hygienic Practices:WASH THOROUGHLY AFTER USE AND BEFORE EATING,
DRINKING, SMOKING OR USING SANITARY FACILITIES .
Supplemental Safety and Health
FIRE FIGHT PROC: SPILLED OXIDIZER MATL. LG QTYS OF PROD MAY MELT. TAKE
CARE NOT TO SCATTER MELT. FIRE/EXPLN HAZ: OXIDE GASES WHICH ARE
ALSO OXIDIZERS. MATL IS REPORTED TO EXPLODE WHEN HEATED ABOVE 100
0F (537C). FIRST AID PROC: VOMIT BY TOUCHING FINGER TO BACK OF
THROAT. CON'T UNTIL VOMIT FLUID IS CLEAR. (SEE INGRED 03)
