=============  Composition/Information on Ingredients  =============

Ingred Name:SODIUM CARBONATE
CAS:497-19-8
RTECS #:VZ4050000

=====================  Hazards Identification  =====================

LD50 LC50 Mixture:LD50 (ORAL, RAT): 4090 MG/KG
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ACUTE: INHALATION: INHALATION OF DUST
    MAY CAUSE IRRITATION TO THE RESPIRATORY TRACT. SYMPTOMS FROM
    EXCESSIVE INHALATION OF DUST MAY INCLUDE COUGHING AND DIFFICULT
    BREATHING. EXCESSIVE CONTACT IS KNOWN  TO CAUSE DAMAGE TO THE NASAL
    SEPTUM. INGESTION: SODIUM CARBONATE IS ONLY SLIGHTLY TOXIC, BUT
    LARGE DOSES MAY BE CORROSIVE TO THE GASTRO-INTESTINAL TRACT WHERE
    SYMPTOMS MAY INCLUDE SEVERE ABDOMINAL PA IN, VOMITING, DIARRHEA,
    COLLAPSE AND DEATH. SKIN: EXCESSIVE CONTACT MAY CAUSE IRRITATION
    WITH BLISTERING AND REDNESS. SOLUTIONS MAY CAUSE SEVERE IRRITATION
    OR BURNS. (EFTS OF OVEREXP).
Effects of Overexposure:HLTH HAZ: EYE: CONTACT MAY BE CORROSIVE TO EYES
    AND CAUSE CONJUCTIVAL EDEMA AND CORNEAL DESTRUCTION. RISK OF
    SERIOUS INJURY INCREASES IF EYES ARE KEPT TIGHTLY CLOSED. OTHER
    SYMPTOMS MAY APPEAR FROM AB SORPTION OF SODIUM CARBONATE INTO THE
    BLOODSTREAM VIA THE EYES. CHRONIC: PROLONGED OR REPEATED SKIN
    EXPOSURE MAY CAUSE SENSITIZATION.
Medical Cond Aggravated by Exposure:NO INFORMATION FOUND.

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

First Aid:INHAL: REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE ARTF RESP.
    IF BREATHING IS DFCLT, GIVE OXYGEN. GET MED ATTN. INGEST: IF
    SWALLOWED, DO NOT INDUCE VOMIT. GIVE LRG QTIES OF H*2O. NEVER GIVE
    ANYTHING B Y MOUTH TO AN UNCON PERSON. GET MED ATTN IMMED. SKIN:
    IMMED FLUSH W/PLENTY OF SOAP & H*2O FOR AT LEAST 15 MIN. REMOVE
    CONTAMD CLOTHING & SHOES. GET MED ATTN. WASH CLOTHING BEFORE REUSE.
    THOROUGHLY CLE AN SHOES BEFORE REUSE. EYE: IMMED FLUSH W/PLENTY OF
    H*2O FOR AT LEAST 15 MIN, LIFTING LOWER & UPPER EYELIDS
    OCCASIONALLY. GET MED ATTN IMMED.  NOTE TO MD: CONSIDER ENDOSCOPY
    IN	ALL SUSPECTED CASES OF	SODIUM CARBONATE POISONING. (SUPDAT)

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

Extinguishing Media:USE ANY MEANS SUITABLE FOR EXTINGUISHING
    SURROUNDING FIRE.
Fire Fighting Procedures:USE NIOSH APPROVED SCBA & FULL PROTECTIVE
    EQUIPMENT . USE PROTECTIVE CLOTHING AND BREATHING EQUIPMENT APPROP
    FOR THE SURROUNDING FIRE.
Unusual Fire/Explosion Hazard:NOT CONSIDERED AN EXPLOSION HAZARD, BUT
    SODIUM CARBONATE MAY EXPLODE WHEN APPLIED TO RED-HOT ALUMINUM.

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

Spill Release Procedures:VENTILATE AREA OF LEAK OR SPILL. WEAR
    APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT AS SPECIFIED IN SECTION
    8. SPILLS: SWEEP UP AND CONTAINERIZE FOR RECLAMATION OR DISPOSAL.
    VACUMMING OR WET SWEEPING MAY  BE USED TO AVOID DUST DISPERSAL.

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

Handling and Storage Precautions:KEEP IN A TIGHTLY CLOSED CNTNR, STORED
    IN A COOL, DRY, VENT AREA. PROTECT AGAINST PHYSICAL DAMAGE. ISOLATE
    FROM INCOMPATIBLE SUBSTANCES. CNTNRS OF THIS MATL MAY BE HAZ WHEN
    EMPTY SINCE THEY RETAIN PRO D RESIDUCES (DUST, SOLIDS); OBESERV ALL
    WARNINGS & PRECAUTIONS LISTED FOR  PROD.

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

Respiratory Protection:FOR CONDITIONS OF USE WHERE EXPOSURE TO
    DUST/MIST IS APPARENT, A NIOSH APPROVED HALF-FACE DUST/MIST
    RESPIRATOR MAY BE WORN. FOR EMERGENCIES/INSTANCES WHERE EXPOSURE
    LEVELS ARE NOT KNOWN, USE A NIOSH A PPROVED FULL-FACE
    POSITIVE-PRESSURE,	NIOSH APPROVED AIR-SUPPLIED RESPIRATOR.
    WARNING: AIR-PURIFYING RESP DO NOT PROTECT WORKERS IN
    OXYGEN-DEFICIENT ATMOSPHERE.
Ventilation:SYS OF LOC &/GENERAL EXHST IS REC TO KEEP EMPLOYEE EXPOS AS
    LOW AS POSS. LOC EXHST VENT IS GENERALLY PREFERRED BECAUSE IT CAN
    CONTROL EMISSIONS OF (SUPDAT)
Protective Gloves:IMPERVIOUS GLOVES .
Eye Protection:ANSI APPROVED CHEMICAL WORKERS GOGGLES & FULL LENGTH
    FACESHIELD .
Other Protective Equipment:EYE WASH AND DELUGE SHOWER MEETING ANSI
    DESIGN CRITERIA . WEAR PROTECTIVE GLOVES AND CLEAN BODY-COVERING
    CLOTHING.
Work Hygienic Practices:WASH THOROUGHLY AFTER HANDLING.
Supplemental Safety and Health
FIRST AID PROC: PERFORM BLOOD ANALYSIS TO DETERM IF DEHYDRATION,
    ACIDOSIS/OTHER ELECTROLYTE IMBALANCE OCCURRED. VENT: CONTAM AT ITS
    SOURCE, PREVENTING DISPERSION OF IT INTO GENERAL WORK AREA. PLEASE
    R EFER TO ACGIH DOCUMENT, INDUSTRIAL VENTILATION, MANUAL OF REC
    PRACTICES, MOST RECENT EDITION, FOR DETAILS.
