Pool Chemical

A variety of chemicals are used to control water conditions in swimming pools, spas and hot tubs. Try to give away unused swimming pool chemicals. If you are unable to give chemicals away, contact a hazardous waste vendor.

They include disinfectants (such as chlorine), algaecides, chlorine stabilizers, oxidizers, alkalinity adjusters, pH adjusters and water conditioners. 

Of the disinfectants, calcium hypochlorite is an extremely volatile chemical when mixed with organic compounds. It can react with combustible materials such as paper, cloth or wood and cause fire or explosion if improperly handled. 

Gaesous chlorine is highly toxic. Store pool chemicals in non-combustible containers. 

Store acid products separately from oxidizers and bases. Do not store any of the oxidizing chemicals on wooden pallets. 

The Washington State Public Health Association and the Washington State Environmental Health Association have published Pool Operator's Manual, A Guide to Safe and Healthy Operations of Pools.
