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)

=======================  First Aid Measures  =======================

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)

=====================  Fire Fighting Measures  =====================

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)

==================  Accidental Release Measures  ==================

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  ======================

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).

=============  Exposure Controls/Personal Protection  =============

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)
