HARMFUL
CONTACT WITH COMBUSTIBLE MATERIAL MAY CAUSE FIRE.
HARMFUL BY INHALATION, IN CONTACT WITH SKIN AND IF SWALLOWED.
IRRITATING TO EYES, RESPIRATORY SYSTEM AND SKIN.
CAUSES SEVERE IRRITATION.
AVOID CONTACT WITH ACID.
KEEP AWAY FROM COMBUSTIBLE MATERIAL.
IN CASE OF CONTACT WITH EYES, RINSE IMMEDIATELY WITH PLENTY OF
WATER AND SEEK MEDICAL ADVICE.
TAKE OFF IMMEDIATELY ALL CONTAMINATED CLOTHING.
WEAR SUITABLE PROTECTIVE CLOTHING, GLOVES AND EYE/FACE
PROTECTION.
SECTION 4. - - - - - - - - - - FIRST-AID MEASURES- - - - - - - - - - -
IN CASE OF CONTACT, IMMEDIATELY FLUSH EYES OR SKIN WITH COPIOUS
AMOUNTS OF WATER FOR AT LEAST 15 MINUTES WHILE REMOVING CONTAMINATED
CLOTHING AND SHOES.
ASSURE ADEQUATE FLUSHING OF THE EYES BY SEPARATING THE EYELIDS
WITH FINGERS.
IF INHALED, REMOVE TO FRESH AIR. IF NOT BREATHING GIVE ARTIFICIAL
RESPIRATION. IF BREATHING IS DIFFICULT, GIVE OXYGEN.
IF SWALLOWED, WASH OUT MOUTH WITH WATER PROVIDED PERSON IS CONSCIOUS.
CALL A PHYSICIAN.

ADDITIONAL INFORMATION
THERMAL DECOMPOSITION OF CALCIUM HYPOCHLORITE OCCURS AT APPROXIMATELY
175'C WITH THE EVOLUTION OF OXYGEN AND CHLORINE, PROPAGATING RAPIDLY
THROUGH THE WHOLE BULK. WHEN A CARBON TETRACHLORIDE EXTINGUISHER WAS
USED ON A FIRE IN AN OPEN CONTAINER OF THE HYPOCHLORITE AN EXPLOSION
OCCURRED. AMMONIA, PRIMARY ALIPHATIC OR AROMATIC AMINES REACT WITH
THE HYPOCHLORITE TO PRODUCE EXPLOSIVELY UNSTABLE COMPOUNDS. CALCIUM
HYPOCHLORITE CONTAINING OVER 60% ACTIVE CHLORINE IGNITES ON CONTACT
WITH LUBRICATING OILS, DAMP SULFUR, ORGANIC THIOLS OR SULFIDES. METAL
OXIDES CATALIZE THE OXYGEN-EVOLVING DECOMPOSITION OF THE HYPOCHLORITE.
CONTACT OF THE SOLID HYPOCHLORITE WITH NITROMETHANE, ALCOHOLS,
GLYCEROL, PHENOL OR DIETHYLENE GLYCOL MONOMETHYL ETHER RESULTS IN
IGNITION. HEATING A CONFINED MIXTURE OF THE HYPOCHLORITE AND CARBON
RESULTED IN AN EXPLOSION.
SECTION 8. - - - - - - EXPOSURE CONTROLS/PERSONAL PROTECTION- - - - - -
WEAR APPROPRIATE NIOSH/MSHA-APPROVED RESPIRATOR, CHEMICAL-RESISTANT
GLOVES, SAFETY GOGGLES, OTHER PROTECTIVE CLOTHING.
SAFETY SHOWER AND EYE BATH.
USE ONLY IN A CHEMICAL FUME HOOD.
AVOID BREATHING DUST.
DO NOT GET IN EYES, ON SKIN, ON CLOTHING.
AVOID PROLONGED OR REPEATED EXPOSURE.
WASH THOROUGHLY AFTER HANDLING.
SEVERE IRRITANT.
HARMFUL SOLID.
AVOID CONTACT WITH ACID.
KEEP TIGHTLY CLOSED.
KEEP AWAY FROM COMBUSTIBLE MATERIALS, HEAT, SPARKS, AND OPEN FLAME.
STORE IN A COOL DRY PLACE.

SYMPTOMS OF EXPOSURE MAY INCLUDE BURNING SENSATION, COUGHING,
WHEEZING, LARYNGITIS, SHORTNESS OF BREATH, HEADACHE, NAUSEA AND
VOMITING.
TO THE BEST OF OUR KNOWLEDGE, THE CHEMICAL, PHYSICAL, AND
TOXICOLOGICAL PROPERTIES HAVE NOT BEEN THOROUGHLY INVESTIGATED.
ADDITIONAL INFORMATION
IF SWALLOWED CALCIUM HYPOCHLORITE CAN PRODUCE NAUSEA, VOMITING,
DELIRIUM, COMA, RESPIRATORY COLLAPSE, HOLES IN THE ESOPHOGUS AND

SECTION 13. - - - - - - - - - DISPOSAL CONSIDERATIONS - - - - - - - - -
CAUTIOUSLY ACIDIFY A 3% SOLUTION OR A SUSPENSION OF THE MATERIAL TO
PH 2 WITH SULFURIC ACID. GRADUALLY ADD A 50% EXCESS OF AQUEOUS SODIUM
BISULFITE WITH STIRRING AT ROOM TEMPERATURE. AN INCREASE IN TEMPERA-
TURE INDICATES THAT A REACTION IS TAKING PLACE. IF NO REACTION IS
OBSERVED ON THE ADDITION OF ABOUT 10% OF THE SODIUM BISULFITE SOLUTION
INITIATE IT BY CAUTIOUSLY ADDING MORE ACID. IF MANGANESE, CHROMIUM,
OR MOLYBDENUM ARE PRESENT ADJUST THE PH OF THE SOLUTION TO 7 AND TREAT
WITH SULFIDE TO PRECIPITATE FOR BURIAL AS HAZARDOUS WASTE. DESTROY
EXCESS SULFIDE, NEUTRALIZE AND FLUSH THE SOLUTION DOWN THE DRAIN.
OBSERVE ALL FEDERAL, STATE AND LOCAL ENVIRONMENTAL REGULATIONS.
