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 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION

Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 7778-54-3:
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use.

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. Hazardous Polymerization: Has not been reported.
