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

LD50 LC50 Mixture:NONE SPECIFIED BY MANUFACTURER.
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:SODIUM HYDROXIDE IS STRONG ALKALI & IS
    CORR TO ANY TISS W/WHICH IT COMES IN CNTCT. INHAL EFTS MAY VARY
    FROM MILD IRRIT TO DESTRUCTIVE BURNS DEPENDING ON SEV OF EXPOS. SEV
    PNEUM MAY OCCUR. SODIUM HYDRO XIDE MAY CAUSE EYE IRRIT & W/GREATER
    EXPOS, SEV BURNS W/POSS BLINDNESS. SKIN CNTCT W/SODIUM HYDROXIDE
    (EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ: MAY CAUSE IRRIT & W/GREATER EXPOS,
    SEV BURNS W/SCARRING. SWALLOW SODIUM HYDROXIDE MAY CAUSE SEV BURNS
    OF MOUTH, THROAT & STOM. DEATH MAY RSLT. SEV SCARRING OF THROAT MAY
    OCCUR ON RECOVERY. I NCRD NUMBER OF ESOPHAGEAL CANCER CASES
    REPORTED IN PERS HAVING ESOPHAGUS SCARRING FROM SWALLOWING SODIUM
    HYDROXIDE.
Medical Cond Aggravated by Exposure:THERE ARE NO DATA AVAILABLE WHICH
    ADDRESS MEDICAL CONDITIONS THAT ARE GENERALLY RECOGNIZED AS BEING
    AGGRAVATED BY EXPOSURE TO SODIUM HYDROXIDE.

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

First Aid:CALL POIS CNTR/MD IMMED. INGEST:IMMED GIVE SEVERAL GLASSES OF
    WATER BUT DO NOT INDUCE VOMIT. IF VOMIT OCCURS, GIVE FLUIDS AGAIN.
    HAVE MD DETERM IF CNDTN PERMITS INDUCTION OF VOMIT OR EVACUATION OF
    STO M. DO NOT GIVE ANYTHING BY MOUTH IF UNCON/CONVULSING.
    SKIN:UNDER SFTY SHOWER, IMMED FLUSH ALL AREAS W/LG AMTS OF RUNNING
    WATER FOR AT LST 15 MIN. REMOVE CONTAMD CLTHG & SHOES. DO NOT
    ATTEMPT (ING 5)

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

Flash Point:NONE
Extinguishing Media:USE WATER SPRAY, DRY CHEMICALS OR CARBON DIOXIDE.
Fire Fighting Procedures:NIOSH APPRVD SCBA & FULL PROT EQUIP KEEP
    FIRE-EXPOS CNTNRS COOL W/WATER SPRAY TO PVNT RUPTURE DUE TO EXCESS
    HEAT. HIGH PRESS WATER HOSE MAY SPREAD(SUPDAT)
Unusual Fire/Explosion Hazard:NOT CONSIDERED FLAM/COMBUST. DOES NOT
    SUPPORT COMBUST, BUT CNTCT W/WATER OR ACIDS MAY GENERATE SUFFICIENT
    HEAT TO IGNITE NEARBY COMBUST MATLS. CNTCT (SUPDAT)

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

Spill Release Procedures:FOLLOW GOOD INDUS HYGIENE PRACT. IF ENTERING
    UNKNOWN CONC OF MIST USE NIOSH APPRVD POS-PRESS, SCBA OR POS-PRESS,
    SUPPLIED-AIR RESP W/ESCAPE PACK. HNDL SM SPILLS ROUTINELY. USE ADEQ
    VENT &/OR WEAR NIOS H APPRVD DUST, MIST & FUME RESP. WEAR (ING 13)
Neutralizing Agent:DILUTE ACID (PREFERABLY ACETIC ACID). SODIUM
    BICARBONATE.

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

Handling and Storage Precautions:STORE IN COOL,DRY,WELL VENTD AREA AWAY
    FROM STRONG ACIDS, FLAM MATLS & HEAT/FLAME SOURCES. STORE AWAY FROM
    FOODSTUFF/ANIMAL FEED. PVNT CNTNR DMG/LEAK.
Other Precautions:NON-CORR TO RUB AT ATM TEMPS. SODIUM HYDROXIDE IS
    SLOWLY CORR TO IRON, COPPER & GLASS. ALUMINUM, TIN & ZINC (INCL
    ALLOYS CONTAINING ANY OF THESE METALS) WILL BE ATTACKED & ARE
    UNSUITABLE AS MATLS OF C ONSTRUCTION. AT ELEVATED TEMPS,(ING 19)

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

Respiratory Protection:IF CNDTNS GENERATE AIRBORNE MIST, HNDL ONLY IN
    OPEN (EG OUTDOOR) OR WELL VENTD AREA. WHERE ADEQ VENT IS NOT AVAIL,
    USE NIOSH APPRVD DUST, MIST & FUME RESPS TO REDUCE EXPOS. WHERE
    EXPOS POTENTL UNDER U SE CNDTNS NECESSITATES HIGHER (ING 21)
Ventilation:LOC EXHST VENT, ENCLSD SYS DESIGN OR PROCESS ISOLATION &
    REMOTE CTL IN COMBINATION W/APPROP USE OF PERSONAL PROT EQUIP.
Protective Gloves:IMPERVIOUS GLOVES.
Eye Protection:ANSI APPRVD CHEM WORKERS GOGGS (ING 23)
Other Protective Equipment:ANSI APPROVED EYE WASH & DELUGE SHOWER .
    IMPERVIOUS CLTHG & FOOTWEAR TO PVNT SKIN CNTCT W/LIQ OR ITS
    AEROSOL.
Work Hygienic Practices:KEEP ALL FOOD IN SEPARATE AREA AWAY FROM
    STORAGE/USE LOCATION. EATING, DRINKING & SMKNG SHOULD BE PROHIBITED
    (ING 24)
Supplemental Safety and Health
FIRE FIGHT PROC:PROD FROM BROKEN CNTNRS INCR CONTAM/FIRE HAZ. CONTAMD
    BLDGS, AREAS & EQUIP MUST NOT BE USED UNTIL PROPERLY DECONTAMD.
    COMBUST PRODS IRRIT RESP TRACT & MAY CAUSE BRTHG DFCLTY & PULM EDE
    MA; SYMPS MAY BE DELAYED. EXPLO HAZ: W/CERTAIN METALS SUCH AS
    ALUMINUM, TIN/ZINC WILL EVOLVE FLAM & EXPLO HYDROGEN GAS.
