Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:EXPOSURE TO SODIUM CARBONATE DUST OR
    MIST CAN CAUSE IRRITATION TO EYES, SKIN & UPPER RESPIRATORY TRACT.
    EXCESSIVE CONTACT W/THIS MATERIAL HAS CAUSED SODA ULCERS ON HANDS &
    PERFORATION OF NASAL SEPTUM  (WALL DIVIDING NASAL PASSAGES).
    PROLONGED OR REPEATED CONTACT CAN PRODUCE A SENSITIVITY REACTION.
    THIS (EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ:MATL IS SLIGHTLY TOX BY INGEST, BUT LG
    AMTS CAN BE CORR TO GI TRACT, PRDCG ABDOM PAINS, VOMIT & DIARR.
    CONC SOLNS IN PRLNG CONT W/SKIN &/OR EYES CAN DESTROY TISS. SIGNS &
    SYMPS OF EXPOS:SKIN  & EYE IRRIT, ABDOM PAIN, VOMIT & DIARRHEA ARE
    SYMPTOMATIC OVER-EXPOSURE. TARGET ORGANS:SKIN & GI TRACT.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

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

First Aid:SKIN:REMOVE CONTAM SHOES & CLTHG. RINSE AFFECTED AREA W/LG
    AMTS OF WATER FOLLOWED BY WASHING AREA W/SOAP & WATER. CONT MED
    ASSISTANCE IF NEC. EYE:IMMED FLUSH, INCL UNDER EYELIDS, W/COPIOUS
    AMTS OF WAT ER FOR AT LST 15 MINS. CONT MED ASSISTANCE IF NEC.
    INHAL:REMOVE VICTIM TO FRESH AIR. IF BRTHG IS DFCLT, GIVE OXYG; IF
    VICTIM IS NOT BRTHG, GIVE ARTF RESP. CONT MED ASSISTANCE IF NEC.
    INGEST: (ING 4)

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

Extinguishing Media:USE EXTINGUISHING MEDIA THAT IS APPROPRIATE TO
    SURROUNDING FIRE. THIS MATERIAL IS NONCOMBUSTIBLE.
Fire Fighting Procedures:USE NIOSH/MSHA APPROVED SCBA & FULL PROTECTIVE
    EQUIPMENT .
Unusual Fire/Explosion Hazard:EXPLO CAN OCCUR IF SODIUM CARBONATE COMES
    IN CONT W/RED-HOT ALUMINUM METAL. NOTE:SODIUM CARBONATE IS
    DECOMPOSED BY ACIDS W/EFFERVESCENCE. ENDOTHERMIC (SUPDAT)

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

Spill Release Procedures:NOTIFY SFTY PERS OF MAJOR SPILLS &/OR LEAKS.
    AVOID PRDCG DUST. PERS INVOLVED IN CLEAN-UP NEED PROT AGAINST SKIN
    CONT & INHAL OF DUST/MIST. SCOOP UP SOLID FOR RECOVERY/DISP. FLUSH
    RESIDUES & LIQ SPILLS  TO HOLDING AREA FOR NEUT BEFORE DISCHARGE.
Neutralizing Agent:NEUTRALIZE MATERIAL W/DILUTE HCL.

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

Handling and Storage Precautions:DO NOT EAT, DRINK/SMOKE IN AREAS OF
    STOR/USE. STORE MATL IN TIGHTLY CLSD CNTNR, IN CLEAN, DRY,
    WELL-VENTILATED AREA, AWAY FROM STRONG ACIDS.
Other Precautions:PROT CNTNRS FROM PHYSICAL DMG. AFFINITY OF SODIUM
    CARBONATE TO ABSORB MOISTURE & CO*2 CAN CAUSE LUMPING & REDUCTION
    OF ALKALINITY. ON EXPOS TO AIR IT WILL GRADUALLY ABSORB 1 MOL OF
    WATER (ABOUT 15%).	THIS MATL WILL BEGIN TO LOOSE (ING 8)

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

Respiratory Protection:A NIOSH/MSHA APPROVED SELF-CONTAINED RESPIRATOR

    CONDITIONS FOR INHALATION PROTECTION.
Ventilation:USE GENERAL & LOCAL EXHAUST VENT TO MEET TLV FOR NUISANCE
    DUST & TO PREVENT IRRIT CONCS OF DUST & MIST IN WORKPLACE.
Protective Gloves:RUBBER GLOVES.
Eye Protection:ANSI APPROVED CHEM WORKERS GOGGS(ING 10)
Other Protective Equipment:EYE WASH FOUNTAIN & DELUGE SHOWER WHICH MEET
    ANSI DESIGN CRITERIA . PERS HNDLG THIS MATL SHOULD ALSO WEAR (ING
    11)
Work Hygienic Practices:IF CLTHG BECOMES CONTAM W/THIS MATL, LAUNDER
    BEFORE RE-USE. NOTE:CONT LENSES POSE SPECIAL PROB; SOFT LENSES MAY
