cause irritation and inflammation to the respiratory tract. Harmful or fatal if swallowed. Strong
Oxidizing Agent! Mix only with water. Never add water to product. Always add the product to large

0461 Calcium Hypochlorite Granular 70%
quantities of water. Do not mix with any other chemicals. Contamination with moisture, acids, organic
materials and other easily combustible materials such as petroleum, paint products, wood or paper
may cause fire or explosion and the liberation of hazardous gases. Do not add this product to any
dispensing device containing remnants of any other product. Such use may cause violent reaction
leading to fire or explosion. Very toxic to aquatic organisms.
Precautions: Do not get in eyes, on skin, or on clothing. Avoid breathing dust. Irritating to nose
and throat. Do not swallow. Do not eat, drink or smoke in work area. Wash hands after handling.
Remove and wash contaminated clothing before reuse. Keep out of reach of children.
4. FIRST AID MEASURES
INHALATION: Remove from area to fresh air. If symptomatic, contact a poison control center,
emergency room or physician for treatment information.
EYE/SKIN CONTACT: EYE: Remove contact lens and pour a gentle stream of warm water
through the affected eye for at least 15 minutes. Contact a poison control center, emergency room or
physician right away as further treatment will be necessary. SKIN: Run a gentle stream of water over
the affected area for 15 minutes. A mild soap may be used if available. Contact a poison control
center, emergency room or physician right away as further treatment will be necessary.
INGESTION: Gently wipe or rinse the inside of the mouth with water. Sips of water may be given
if person is fully conscious. Never give anything by mouth to an unconscious or convulsing person.
Do Not induce vomiting. Contact a poison control center, emergency room or physician right away as
further treatment will be necessary.
5. FIRE FIGHTING MEASURES
FLASH POINT: Not Applicable.
EXTINGUISHING MEDIA: Drench with large quantities of water only. Do not use dry chemicals or
foams. Product supplies own oxygen, therefore attempts to smother fire with a wet blanket, carbon
dioxide, dry chemical extinguisher or other means are not effective.
SPECIAL FIREFIGHTING PROCEDURES: Product decomposes at approximately 338-356掳F (170-
180掳C) releasing oxygen gas. Container may rupture. Fire-fighters must wear NIOSH approved,
pressure demand, self-contained breathing apparatus with full face piece for possible exposure to
hazardous gases. Emits toxic fumes under fire conditions.
6. ACCIDENTAL RELEASE MEASURES
ACTION TO BE TAKEN IF MATERI AL IS RELEASED OR SPILLED:
Use extreme caution in handling spilled material. Do not mix with any other chemicals.
Contamination with moisture, acids, organics or other easily combustible materials such as
petroleum, paint products, wood or paper may cause fire or violent decomposition. If fire or
decomposition occurs in area of spill, immediately douse with plenty of water. Otherwise, sweep up
all visible material using a clean (new, if possible), dry shovel and broom and dissolve material in
Page 2 of 7
01/02/2004
0461 Calcium Hypochlorite Granular 70%
water. Spilled material that has been swept up and dissolved in water should be used immediately in
the normal application for which this product is being consumed.
7. HANDLING AND STORAGE
PRECAUTIONS TO BE TAKEN DURING HANDLING AND STORAGE:
Store in a cool, dry, well-ventilated place. Keep in original container. Keep container closed when not
in use. Keep away from heat, sparks, flames, direct sunlight, and other sources of heat, including
lighted tobacco products. Use only a clean (new, if possible), dry scoop made of metal or plastic each
time product is taken from the container. Do not add this product to any dispensing device containing
remnants of any other product. Such use may cause violent reaction leading to fire or explosion. Add
this product only to water. Never add water to product. Always add the product to large quantities of
water. May cause fire or explosion if mixed with other chemicals. Fire may result if contaminated with
acids, organic materials and other easily combustible materials such as oil, kerosene, gasoline, paint
products wood and paper. Do not reuse container. Re sidual material remaining in empty container
can react to cause fire. Thoroughly flush empty container with water then destroy by placing in trash
collection. Do not contaminate water, food, or feed by storage or disposal of this product.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Limits:
8-hour Time Weighted Average (TWA); 15-minute Short-Term Exposure Limit (STEL)
OSHA: The OSHA exposure limit(s) for Calcium hydroxide: 5 mg/m3 TWA. Calcium carbonate: 15
mg/m3 (total dust) 5 mg/m3 (respirable dust)
ACGIH: The ACGIH exposure limit(s) for Calcium hydroxide: 5 mg/m3 TWA. Calcium carbonate: 10
mg/m3 (total dust) 3 mg/m3 (respirable nuisance particulate) TWA.
Calcium hypochlorite: 1 mg/m3 TWA. 2 mg/m 3 STEL.
PPG (IPEL):
RESPIRATORY PROTECTION: Where the potential for exposure to dust exists, use the
appropriate regulatory compliant full facepiece air-purifying respirator with acid gas cartridge and
particulate prefilter. Carefully read and follow the respirator manufacturer's instructions and
information.
VENTILATION: Use local exhaust or general room/dilution ventilation sufficient to maintain
employee exposure below permissible exposure limits.
EYE AND FACE PROTECTION: Splashproof goggles and faceshield.
PROTECTIVE GLOVES: Butyl rubber. Neoprene. Nitrile.
OTHER PROTECTIVE EQUIPMENT: Boots, aprons, or chemical suits should be used when
necessary to prevent skin contact.

EFFECTS OF OVEREXPOSURE:
ACUTE:
Page 4 of 7
01/02/2004
0461 Calcium Hypochlorite Granular 70%
Inhalation: Inhalation of calcium hypochlorite dust and deposition of particles in the respiratory tract
can lead to irritation of the tissue and cause a variety of effects. These effects are dependent on
concentration and include: upper respiratory tract irritation, nasal congestion, coughing, sore throat,
laryngitis and shortness of breath. In operations where there are high concentrations of respirable
particulates, pulmonary edema (fluid in the lung) may be produced. If not treated immediately,
pulmonary edema can be life threatening. Since this product is in granular or tablet form, particles of
respirable size are not generally encountered.
Eye/Skin: Calcium hypochlorite is corrosive to the eyes. Contact of calcium hypochlorite dust with
the eyes, even a minute amount for a short duration, can cause severe irritation and even blindness.
Contact with the skin may cause severe irritation, burns, or tissue destruction. In studies utilizing
rabbits, the skin irritation score was 8/8 and the eye irritation score was 98.5/110.
Ingestion: Calcium hypochlorite, if swallowed, causes severe burns to the digestive tract and can be
fatal.
CHRONIC:
Genotoxicity: Calcium hypochlorite produced positive responses in in-vitro assays using bacterial
systems (the Ames test) and chromosomal aberrations in Chinese hamster fibroblasts. In a whole
animal experiment (mouse micronucleus test), exposures ranging from 20 to 160 mg/kg produced no
compound related chromosomal abnormalities.
Carcinogenisis: Although no study has been conducted with calcium hypochlorite, the carcinogenic
potential of sodium hypochlorite was studied in F344 rats. After 104 weeks of drinking water
containing up to 2000 ppm sodium hypochlorite, there was no evidence that this chemical produced
any carcinogenic response. In addition, this exposure did not result in any adverse effects
12. ECOLOGICAL INFORMATION
ECOTOXICOLOGICAL INFORMATION:
0.088 mg/l (Bluegill) 96-hour LC50. Extreme toxicity.
ENVIRONMENTAL FATE:
No data at this time.
13. DISPOSAL CONSIDERATIONS
DISPOSAL METHOD:
Spilled material that has been swept up and dissolved in water should be used immediately in the
normal application for which this product is being used. If this is not possible, dissolve material in
water and carefully neutralize dissolved material by adding hydrogen peroxide (one pint of 35%
hydrogen peroxide solution per pound of calcium hypochlorite to be neutralized) then dilute the
neutralized material with plenty of water and flush to sewer. Note: Only properly neutralized material
should be flushed to sewer. Unneutralized material can cause environmental damage to receiving
water or can interfere with treatment plant operation. Care must be taken when using or disposing of
