These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
CALCIUM HYPOCHLORITE is a powerful oxidizing agent, particularly in the presence of water or at higher temperature as Calcium hypochlorite decomposes to release oxygen and chlorine gases. As strong oxidant Calcium hypochlorite may react with vigor in combination with carbon, especially finely divided is explosive; acetylene, leads to creation of explosive chloroacetylenes; organic matter, oil, hydrocarbons; alcohols may cause explosion, methanol, ethanol, etc.; nitromethane caused delayed violent reaction; organic sulfur compounds, sulfides tend toward ignition and sometimes explosion; with iron oxide in metal containers catalyze oxygen evolving decomposition of the oxidant. Calcium hypochlorite forms highly explosive NCl3 on contact with urea. Produces highly toxic gaseous chlorine gas when heated or on contact with acids [Sax, 9th ed., 1996, p. 1905]. Mixture of damp sulfur with hypochlorite caused a violent reaction, that ejected molten sulfur, Chem Eng. News, 1965, 46(29), 6.
Bleaching of wood pulp, linen, cotton, straw, oils, soaps, and in laundering; oxidizer in calico printing to obtain white designs on a colored ground; destroying caterpillars; disinfecting drinking water, sewage, etc.; as a decontaminant for mustard gas and similar substances.
Calcium hypochlorite, Ca(OCl)2.4H20, also known as calcium oxychloride, chlorinated lime, and bleach, is a deliquescent white powder used as a bleaching agent in the textile and pulp industries and as a disinfectant. It contains 60 to 65% available chlorine,
Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
Calcium hypochlorite (molecular formula: Ca (ClO)2) is a kind of inorganic compound. It appears as a white granular solid with chlorine odor. Though it is relatively stable and non-combustible, it will accelerate the burning of combustible materials. Sodium hypochlorite solid is generally not commercialized. Instead, it is highly soluble in water and can be formulated into various concentrations. The resulting sodium hypochlorite solutions appears as clear, green to yellow liquids. It has two major applications. One is sanitation. For this purpose, it is primarily used as bleaching agent or disinfectants to sanitize publish swimming pools as well as disinfect drinking water. It is also used in the disinfection of surfaces and equipment of kitchen and bathroom. Moreover, it can be used as algaecides, herbicide and laundry detergents. Another major application is in organic chemistry. It can act as a general oxidizing agent for the cleavage of glycols, keto acids to obtain fragmented aldehydes or carboxylic acid. It can also be used for the manufacture of chloroform. Calcium hypochlorite can be manufactured through the reaction between limes (Ca(OH)2) with chlorine gas to give various concentrations of products. Calcium hypochlorite is toxic. Its solution can emit toxic gases such as chlorine. Inhalation can lead to olfactory fatigue and irritation on the lung airway. It is also irritating to the skin and eye upon contact. Ingestion of it can cause vomiting and corrosive injury to the gastrointestinal tract.
Calcium hypochlorite, hydrated is a white granular solid or tablets compressed from the granules having an odor of chlorine. Calcium hypochlorite is noncombustible, but Calcium hypochlorite will accelerate the burning of combustible materials. Calcium hypochlorite is decomposed by water with evolution of chlorine gas and heat. Prolonged exposure to fire or heat may result in the vigorous decomposition of the material and rupture of the container. Material containing less than 39% available chlorine may undergo reactions as described above though Calcium hypochlorite may take longer to initiate, and the resulting reactions may not be as vigorous. Calcium hypochlorite is used for water purification, disinfectant for swimming pools, for bleaching paper and textiles, and for many other uses.
