Fire Fighting Procedures
If material involved in fire: Extinguish using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. /Chlorinated lime, liquid/
Personnel protection: ... Wear positive pressure self-contained breathing apparatus when fighting fires involving this material. /Chlorinated lime, liquid/
Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Use flooding quantities of water as fog or spray. Use water spray to keep fire-exposed containers cool. Fight fire from protected location or maximum possible distance. Do not use dry chemical fire extinguishers containing ammonium compounds. /Calcium hypochlorite, dry, or calcium hypochlorite, mixtures, dry/
Fire Potential
Contact with combustible materials will increase fire hazard. May undergo accelerated decomposition with release of heat above 350 deg F (177 deg C). /Calcium hypochlorite, dry, or calcium hypochlorite, mixtures, dry/
CONTACT OF SOLID HYPOCHLORITE WITH GLYCEROL, DIGOL MONOMETHYL ETHER, OR PHENOL CAUSES IGNITION WITHIN FEW MINUTES, ACCOMPANIED BY IRRITANT SMOKE, PARTICULARLY WITH PHENOL (FORMATION OF CHLOROPHENOLS).

Other Preventative Measures
... ADEQUATE EXHAUST & GENERAL VENTILATION IS NECESSARY TO PREVENT FORMATION OF DANGEROUS CONCENTRATION OF CHLORINE GAS. /CHLORINATED LIME/
If material not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Neutralize spilled material with crushed limestone, soda ash, or lime. /Chlorinated lime, liquid/
Personnel protection: Avoid breathing vapors. Avoid bodily contact with the material ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amt of water or soap and water. ... If contact with the material anticipated, wear appropriate chemcial protective clothing. /Chlorinated lime, liquid/
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Dissolve the material in water and add to a large vol of concn reducing agent soln, then acidify the mixture with sulfuric acid. When reduction is complete, soda ash is added to make the soln alkaline. The alkaline liquid is decanted from any sludge produced, neutralized, and diluted before discharge to a sewer or stream. The sludge is landfilled. /Chlorinated lime/

10.3 Possibility of hazardous reactions

Contact with combustible materials will increase fire hazard. May undergo accelerated decomposition with release of heat above 350 deg F (177\u00b0C). /Calcium hypochlorite, dry, or calcium hypochlorite, mixtures, dry/CALCIUM HYPOCHLORITE is a powerful oxidizing agent, particularly in the presence of water or as it decomposes when heated to release oxygen and chlorine gases. May react vigorously with carbon; reacts potentially explosively with finely divided carbon. Reacts with acetylene to form explosive chloroacetylenes. Reactions with organic matter, oil, hydrocarbons; alcohols may lead to explosions. Reactions with nitromethane, methanol, ethanol (and other alcohols) can become violent after a delay. Reacts with possible ignition and/or explosion with organic sulfur compounds and with sulfides. Decomposes evolving oxygen, a change that can be catalyzed by rust on metal containers. Forms highly explosive NCl3 on contact with urea or ammonia. Evolves highly toxic gaseous chlorine gas when heated or on contact with acids [Sax, 9th ed., 1996, p. 1905]. A mixture with damp sulfur reacted violently, and molten sulfur was ejected [Chem Eng. News, 1965, 46(29), 6]. The combination of calcium hypochlorite, sodium hydrogen sulfate, starch, and sodium carbonate, when compressed, caused the materials to incandescence, followed by explosion, [Ind. Eng. Chem., 1937, 15, 282].

10.4 Conditions to avoid

no data available

10.5 Incompatible materials

Reacts with water and with acids releasing chlorine. Forms explosive compounds with ammonia and amines. Strong oxidizer. Other incompatible materials include organics, nitrogen containing compounds, dry chemical fire extinguishers containing mono-ammonium phosphate, combustible or flammable materials. /Calcium hypochlorite, dry or calcium hypochlorite, mixtures, dry/

10.6 Hazardous decomposition products

The 70% grade may decomp violently if exposed to heat or direct sunlight. Gives off chlorine and chlorine monoxide above 350 deg F (poisonous gases).

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
