Emergency Overview
------------------------------
DANGER! Strong oxidizing agent! Mix only with water. Contamination may c
ause fire or explosion. Do not add this product to any dispensing device
containing remnants of any other product.
Precautions: Do not swallow. Swallowing may cause injury or death. Do not
get in eyes, on skin, or on clothing. May cause burns. Avoid breathing dus
t. Irritating to nose and throat. Wash hands after handling. Keep out of
reach of children.
------------------------------
Inhalation: Move person to fresh air. If not breathi
ng, give artificial respiration, preferably mouth-to-mouth. If breathing i
s difficult, give oxygen. Call a physician.
Eye/skin Contact: In case of contact, immediately flush eyes and skin with
plenty of water (soap and water for skin) for at least 15 minutes, while r
emoving contaminated clothing and shoes. For eye contact, get immediate me
dical attention. If skin irritation occurs, get medical attention.
Ingestion: If swallowed, give at least 3-4 glasses of water, but do not ind
uce vomiting. Do not give anything by mouth to an unconscious or convulsi
ng person. Get medical attention.
Notes to Physician: Treat symptomatically.
-
Flash Point: none
Extinguishing Media: water only. Smothering ineffective - product supplies
own oxygen.
Special Firefighting Procedures: product decomposes at 1800c releasing oxy
gen gas. Container may rupture. Fire-fighters must wear NIOSH approved, pr
essure demand, self-contained breathing apparatus with full face piece for
possible exposure to hazardous gases.
Action to be Taken if Material is Released or Spilled: cal hypo use extreme caution in handling spilled material. Contamination with organic or combustible material may cause fire or violent decomposition. If fire or decomposition occurs in area of spill, immediately douse w
ith plenty of water. Otherwise, sweep up all visible material using a cle
an, dry shovel and broom and dissolve material in 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.
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 pro
ducts. Use only a clean, 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. May cause fire or explosion if mixed with other chemicals. Fire may result if contaminated with acids or easily combustible materials such as oil, kerosene, gasoline, paint products and most other organic materials. Do not reuse container. Residual material remaining in empty drum 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.
Exposure Limits: 8-hour time weighted average (twa); 15-minute short-term exposure limit
(stel)
OSHA: no occupational exposure limits have been established by OSHA for thi
s product.

his product.
Ppg (ipel):1 mg/cu.M. Twa. 2 Mg/cu.M. Stel.
Respiratory protection: if dusty conditions are encountered, use NIOSH approved respirator with acid gas cartridge and dust prefilter. The respiratory use limitations made by NIOSH or the manufacturer must be observed. Respiratory protection programs must be in accordance with 29 cfr 1910.134.
Ventilation: none required unless dusty conditions are encountered.
Eye and face protection: chemical safety goggles.
Protective Gloves: natural or synthetic rubber.
Other Protective Equipment: boots, aprons, or chemical suits should be used
when necessary to prevent skin contact. Personal protective clothing and
use of equipment must be in accordance with 29 cfr 1910.132 (General requi
rements), .133 (Eye and face protection), and .138 (Hand protection).

acute inhalation lc50: (rat) no mortality at 3.5 Mg/l (1 hour). Irritating.
Acute dermal ld50: (rabbit) >1000 mg/kg. Slight to very low toxicity.
Skin irritation: causes burns.
Eye irritation: causes burns.
Acute oral ld50: (rat) 850 mg/kg. Slight to very low toxicity.
Chronic effects/carcinogenicity: this product is not listed as a carcinogen
or suspected carcinogen by NTP, IARC, or OSHA.
Medical conditions aggravated: none known.
Effects of overExposure: cal hypo Acute:
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, coughi
ng, 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 in blood, clinical chemistry, or other target organs.
One of the major uses of calcium hypochlorite is as a source of chlorine for water sanitization in drinking and recreational water. Studies have been conducted to determine the long-term effects of chlorinated drinking water. Seven generations of rats were given 100 ppm chlorine in their drinking water. No difference in fertility, growth, blood parameters, or specific organ toxicity was observed between control and exposed animals. Two separate animal studies conducted by different government agencies determined that the chlorination of municipal drinking water did not result in toxicity to the developing mouse fetus.
Safe handling of this material on a long-term basis should emphasize mini
mizing repeated acute exposures.

Cal hypo 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, 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. For on-site neutralization, carefully and slowly pour the appropriate quantity of 35% hydrogen peroxide solution over all spilled material then flush area with plenty of water. Care must be taken when using or disposing of chemical materials and/or their containers to prevent environmental contamination. It is your duty to dispose of the chemical materials and/or their containers in accordance with the clean air act, the clean water act, the resource conservation and recovery act, as well as any other relevant federal, state, or local laws/regulation
s regarding disposal.
