REVISION DATE : 03/09/2016 Page 8 of 15
Stability and Reactivity Summary:
Product is not sensitive to mechanical shock or impact. Product is
not sensitive to electrical static discharge. Product will not undergo
hazardous polymerization. Product is an NFPA Class 1 oxidizer.
Not pyrophoric. Not an organic peroxide. If subjected to excessive
temperatures, the product may undergo rapid decomposition,
evolution of chlorine gas, and heat sufficient to ignite combustible
substances. If product is exposed to small amounts of water, it
can react violently to produce heat and toxic gases and spatter.
Use copious amounts of water for fires involving this product.
Conditions to Avoid:
Do not store next to heat source, in direct sunlight, or elevated
storage temperature. Do not store where the daily average
temperature exceeds 95 °F. Prevent ingress of humidity and
moisture into container or package. Always close the lid.
Chemical Incompatibility:
This product is chemically reactive with many substances,
including, e.g., other pool treatment products, acids, organics,
nitrogen-containing compounds, dry powder fire extinguishers
(containing mono-ammonium phosphate), oxidizers, corrosive,
flammable or combustible materials. Do not allow product to
contact any foreign matter, including other water treatment
products. Contamination or improper use may cause a fire,
explosion or the release of toxic gases. If product is exposed to
small amounts of water, it can react violently to produce heat and
toxic gases and spatter.
Hazardous Decomposition Products:
Chlorine
Decomposition Temperature:
170 - 180 °C - , 338 - 356 °F- 170 - 180 °C
