Section 4 - FIRST AID MEASURES
Eyes: Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed. Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician:
Treat symptomatically and supportively.

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with other material may cause fire. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Use water with caution and in flooding amounts. Contaminating or mixing with foreign materials such as combustibles, grease, and fuels can cause fire. Containers may explode when heated.
Extinguishing Media:
Use water only! Do NOT use carbon dioxide or dry chemical. Contact professional fire-fighters immediately. Cool containers with flooding quantities of water until well after fire is out.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions.
Remove all sources of ignition. Provide ventilation. Do not get water inside containers. Do not use combustible materials such as paper towels to clean up spill.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Minimize dust generation and accumulation. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Keep away from heat, sparks and flame. Avoid contact with clothing and other combustible materials. Do not ingest or inhale. Discard contaminated shoes. Use only a clean, dry scoop made of metal or plastic each time product is taken from container. Never use scoops containing remnants of other products as it may cause a violent reaction leading to fire or an explosion.
Storage:
Keep away from sources of ignition. Do not store near combustible materials. Do not store in direct sunlight. Keep container closed when not in use. Store in a tightly closed container. Keep away from acids.

Section 10 - STABILITY AND REACTIVITY
Chemical Stability:
All hypochlorite solutions are unstable and slowly decompose on contact with air. Calcium hypochlorite is corrosive to most metals and will evolve toxic chlorine and chlorine monoxide gas when heated above 350F. Sudden heating above 212F may cause an explosion.
Pure, dry calcium hypochlorite is not sensitive to friction or impact. However, in the presence of small amounts of water, it can decompose to form dangerously unstable dichlorine monoxide, which is sensitive to friction, shock or static spark.
Conditions to Avoid:
High temperatures, ignition sources, dust generation, acids, excess heat, combustible materials, organic materials, reducing agents, moisture, high humidity.
Incompatibilities with Other Materials:
Reducing agents, ammonia, iron oxide, phenols, sulfur, aliphatic amines, acetylene, cyanides (e.g. potassium cyanide, sodium cyanide), sulfides (inorganic, e.g. ferric sulfide, lead sulfide, sodium sulfide), carbontetrachloride, aromatic amines, carbon, ammonium chloride, charcoal, glycerol, air, ethanol, menthol, rust, hydroxy compounds (e.g. ethanol, ethylene glycol, gycerol, sugar), metal oxides, turpentine, diethylene glycol monomethyl ether, acetic acid + potassium, N,N-dichloromethylamine + heat, 1-propanethiol, isobutanethiol, sodium hydrogen sulfate + starch + sodium carbonate, combustible materials (e.g. anthracene, grease, oil, mercaptans, methyl carbitol, nitromethane, organic matter, and propylmercaptan).
Hazardous Decomposition Products:
Hydrogen chloride, oxygen, chlorine, calcium hydroxide, calcium carbonate, dichlorine monoxide, Calcium chlorate.
