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
PNEUMIT MAY OCCUR. SODIUM HYD ROXIDE MAY CAUSE IRRIT OF EYES
W/GREATER EXPOS, SEV BURNS W/POSS BLINDNESS. SKIN CNTCT:MAY CAUSE
IRRIT (EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ:& W/GREATER EXPOS, SEV BURNS
W/SCARRING. INGEST: MAY CAUSE SEV BURNS OF MOUTH, THROAT & STOM.
DEATH MAY RSLT. SEV SCARRING OF THROAT MAY OCCUR ON RECOVERY AFTER
SWALLOWING. INCRD NUMBER OF ES OPHAGEAL CANCER CASES HAVE BEEN
REPORTED TO OCCUR IN PERS HAVING SCARRING OF ESOPHAGUS 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:IF KNOWN EXPOS OCCURS/IF POIS SUSPECTED, DO NOT WAIT FOR
SYMPS. IMMED START RECD PROCS & SIMULTANEOUSLY CNTCT POIS CTR, MD
OR NEAREST HOSPITAL. INFORM PERSON CONTACTED OF TYPE & EXTEND OF
EXPOS, DESCR IBE SYMPS & FOLLOW ADVICE GIVEN. INGEST:MATL IS CORR.
IMMED GIVE SEVERAL GLASSES OF WATER BUT DO NOT INDUCE VOMIT. IF
VOMIT OCCURS, GIVE FLUIDS AGAIN. HAVE MD DETERM IF CNDTN OF PATIENT

Flash Point:NONE
Extinguishing Media:USE STD FIREFIGHTING TECHNIQUES TO EXTING FIRES
INVOLVING THIS MATL - USE WATER SPRAY, DRY CHEMICALS OR CARBON
DIOXIDE.
Fire Fighting Procedures:NIOSH APPRVD SCBA & FULL PROT EQUIP. PRODS OF
COMBUST ARE IRRIT TO RESP TRACT & MAY CAUSE BRTHG DFCLTY & PULM
EDEMA. SYMPS MAY BE DELAYED SEVERAL (SUPDAT)
Unusual Fire/Explosion Hazard:NOT CONSIDERED FLAM/COMBUST. DOES NOT
SUPPORT COMBUST HOWEVER, CNTCT W/WATER/ACIDS MAY GENERATE
