Effects of Overexposure:HLTH HAZ:CHRONIC: UNDER SOME CIRCUMSTANCES
    METHEMOGLOBINEMIA OCCURS IN PERS WHEN NITRATE IS CONVERTED BY
    BACTERIA IN STOM TO NITIRITE. NAUS, VOMIT, DIZZ, RAPID HEARTBEAT,
    IRREG BRTHG, CONVULS, COMA &  DEATH CAN OCCUR SHOULD CONVERSION
    TAKE PLACE. CHRONIC EXPOS TO NITRITES MAY CAUSE ANEMIA & ADVERSE

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

First Aid:INHAL:REMOVE TO FRESH AIR. GET MED ATTN FOR ANY BRTHG DFCLTY.
    INGEST:INDUCE VOMIT IMMED AS DIRECTED BY MED PERS. NEVER GIVE
    ANYTHING BY MOUTH TO UNCON PERS. SKIN:REMOVE ANY CONTAMD CLTHG.
    WIPE OFF EXC ESS FROM SKIN. WASH SKIN W/SOAP & WATERFOR AT LEAST 15
    MIN. GET MED ATTN IF IRRIT DEVEL/PERSISTS. EYE:WASH W/PLENTY OF

    GET(SUPDAT)

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

Extinguishing Media:USE ANY MEANS SUITABLE FOR EXTING SURROUNDING FIRE.
    WATER SPRAY MAY BE USED TO KEEP FIRE EXPOSED CNTNRS COOL.
Fire Fighting Procedures:WEAR NIOSH/MSHA APPRVD SCBA & FULL PROT EQUIP.
    THIS OXIDIZING MATLS CAN INCR FLAMM OF ADJACENT COMBUST MATL.
Unusual Fire/Explosion Hazard:NITRATES MAY EXPLODE WHEN SHOCKED,
    EXPOSED TO HEAT/FLAME/BY SPONT CHEM RXN. NOT COMBUST, BUT IS STRONG
    OXIDIZER & ITS HEAT OF RXN W/REDUCING AGENTS/(SUPDAT)

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

Spill Release Procedures:CLEAN UP SPILL IN MANNER THAT DOES NOT
    DISPERSE DUST INTO AIR. PICK UP SPILL FOR RECOVERY/DISP & PLACE IN
    CLSD CNTNR. (IF SPILLED MATL IS INTERMIXED W/COMBUST IT MAY BE
    DESIRABLE TO WET W/WATER & MIX  W/WET SAND BEFORE PICK-UP FOR
    DISP).
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

======================	Handling and Storage  ======================

Handling and Storage Precautions:KEEP IN TIGHTLY CLSD CNTNR, STORED IN
    COOL, DRY, VENT AREA. PROT AGAINST PHYSICAL DMG. SEPARATE FROM
    COMBUST, ORG/OTHER READILY OXIDIZABLE MATLS.
Other Precautions:DO NOT STORE ON WOODEN FLOORS.

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

Respiratory Protection:FOR CNDTNS OF USE WHERE EXPOS TO DUST IS
    APPARENT, A NIOSH/MSHA DUST/MIST RESP MAY BE WORN. FOR EMERGENCIES,
    A NIOSH/MSHA APPRVD SCBA MAY BE NECESSARY.
Ventilation:LOC EXHST SYS WHICH CAPTURES THE CONTAM AT ITS SOURCE IS
    RECOM TO PVNT DISPERSION OF CNTAMD INTO WORKROOM AIR.
Protective Gloves:RUBBER/NEOPRENE GLOVES.
Eye Protection:ANSI APPRVD CHEM WORKERS GOGGS.
Other Protective Equipment:ANSI APPRVD EMER EYEWASH & DELUGE SHOWER.
    IMPERVIOUS BOOTS, APRON/COVERALLS AS NEEDED IN AREAS OF UNUSUAL
    EXPOS.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
Supplemental Safety and Health
