OSHA: NO
Effects of Exposure: SUMMARY OF RISKS:CALCIUM HYDROXIDE IS STRONG BASE &
ITS SOLID FORM IS MOD CAUSTIC TO ALL BODILY SURF IT CONT. SINCE AQUEOUS SOLNS
HAVE LOW SOL & ARE NOT READILY ABSORBED INTO TISS, PRLNGD CONT IS NEC
FOR TOX. TARGET ORGANS:EYES, SKIN, & MUC MEMB. ACUTE:INGEST CAUSES SEV
PAIN, DIARR, VOMIT (SOMETIMES (EFTS OF OVEREXP)
Explanation Of Carcinogenicity: NOT RELEVANT.
Signs And Symptions Of Overexposure: HLTH HAZ:BLOODY & CONTAINING MUCOSAL
LINING), & COLLAPSE. IF PATIENT SURVIVES 24 HRS, THERE IS POSS OF DELAYED
RXN INVOLVING GASTRIC/ESOPHAGEAL PERFORATION WHICH CAN CAUSE ADDNL SEV ABDOM
PAIN & RAPID DECR IN BLOOD PRESS. ESOPHAGEAL CONSTRICTION MAY PERSIST
AFTER INGEST, MAKING SWALLOWING DFCLT. INHAL OF CALCIUM

Handling and Disposal
=======================================================
Spill Release Procedures: NOTIFY SFTY PERS OF ALL SPILLS & LEAKS. ISOLATE
HAZ AREA, DENY ENTRY, & STAY UPWIND OF SPILLS. CLEANUP PERS SHOULD
PROTECT AGAINST DUST INHAL & SKIN/EYE CONT. SM DRY SPILLS, CAREFULLY
SCOOP UP, PLACE INTO METAL CNTNRS, & COVER FOR LATER
Neutralizing Agent: NONE SPECIFIED BY MANUFACTURER.
Waste Disposal Methods: IN SITE AMELIORATION WHERE SODIUM BICARBONATE/CARBON
DIOXIDE IS USED AS NEUTRALIZING AGENT HAS BEEN FOUND TO BE USEFUL. CONT
SUPPLIER/LICENSED CONTRACTOR FOR DETAILED REC. FOLLOW APPLICABLE FEDERAL, S
TATE, AND LOCAL REGULATIONS.
Handling And Storage Precautions: AVOID PHYSICAL DMG TO CNTNRS. STORE IN COOL,
DRY, WELL-VENTILATED PLACE AWAY FROM EXCESS HEAT & INCOMPAT MATLS.
Other Precautions: CONSIDER PREPLACEMENT & PERIODIC MED EXAMINATION OF
EXPOSWORKERS EMPHASIZING SKIN & RESP TRACT. IF RESPS ARE USED, INSTITUTE
RESP PROT PROGRAM THAT INCLUDES REGULAR TRAINING, MAINTENANCE, INSPECTION,
AND EVALUTION.
=======================================================
Fire and Explosion Hazard Information
=======================================================
Flash Point Text: NONE
Extinguishing Media: CALCIUM HYDROXIDE IS NONFLAM MATL. FOR SM FIRES, USE DRY
CHEM, CO*2, HALON, WATER SPRAY/REGULAR FOAM. LG FIRES, (SUPDAT)
Fire Fighting Procedures: NIOSH APPRVD SCBA & FULL PROT EQUIP (FP N). IF
POSS W/OUT RISK, REMOVE CNTNR. USE WATER SPRAY TO COOL FIRE-EXPOS CNTNRS
UNTIL FIRE IS WELL OUT. STAY
Unusual Fire/Explosion Hazard: CALCIUM HYDROXIDE LOSES WATER WHEN HEATED TO
FORM CALCIUM OXIDE WHICH DOES NOT BURN.
=======================================================
Control Measures
=======================================================
Respiratory Protection: SEE PROFESSIONAL ADVICE PRIOR TO RESP SELECTION &
USE. FOLLOW OSHA RESP REGS (29CFR1910.134) &, IF NEC, WEAR NIOSH APPRVD
RESP. SELECT RESP BASED ON ITS SUITABILITY TO PROVIDE ADEQ WORKER PROT FOR
GIV EN WORKING CNDTNS, LEVEL OF
Ventilation: PROVIDE GEN & LOC EXHAUST VENT SYS TO MAINTAIN AIRBORNE CONCS
BELOW OSHA PEL. LOC EXHAUST VENT IS PREF SINCE
Protective Gloves: IMPERVIOUS GLOVES.
Eye Protection: ANSI APPRVD CHEM WORKERS GOGGLES (FP N).
Other Protective Equipment: ANSI APPRVD EYE WASH & DELUGE SHOWER (FP N). BOOTS,
APRONGS, & GAUNTLETS TO PVNT ALL SKIN CONT.
Work Hygienic Practices: SEPARATE CONTAMD WORK CLOTHES FROM STREET CLOTHES.
LAUNDER CONTAMD WORK CLTHG BEFORE WEARING. REMOVE MATL FROM
Supplemental Safety and Health: SOL IN H*2O:0.185 G/100CC WATER @ 32F(0C) 0.77
G/100 CC WATER @ 212F(100C). APPEAR/ODOR:GRANULES OR POWDER WITH A SLIGHTLY
BITTER ALKALINE TASTE. EXTING MEDIA:USE FOG, WATER SPRAY/REGULAR FOAM. APPLY
WATER AS FAR AWAY AS POSSIBLE. FIRE FIGHT PROC:AWAY FROM ENDS OF TANKS. BE
AWARE OF RUNOFF FROM FIRE CTL METHS.
