SECTION VII - Preeautions of Safe Handting and Use

Stepsto Be Taken in CaseMaterial is Releasedor Spilled:

Material is toxic to fish. Contain in diked area. Neutralize with sodium sulfite, sodium bisulfite, or ferrous

salt solutions. Dilute copiously with water.

Waste Disposal Method: Contain in plastic tank or similar container; use sulfur dioxide gas, sodium sulfite,

sodium bisulfite or ferrous salts. Discharge of treated effluents into lakes, streams or public waters requires

a valid discharge permit. Contact Federal, State, County, and local environmental regulators for guidance.

Precautions to Be Taken in Handling and Storing: Proper handling of sodium hypochlorite solution requires

safety requirements (as described above) and as stated on the labels. Full protection as described above

should be provided when handling bulk shipments of concentrate4 indusrial

sodium hypochlorite solutions. Other Precautions: Strong oxidizing agent. Mix only with water according

to label directions. Store upright in a cool, dry area away from direct sunlight and excessive heat. Do not

store nem other incompatible swimming pool products such as chlorinated isoryanwates or muriatic acid.

Rinse container with water.
