Safe Drinking Water and Toxic Enforcement Act of 1986 [Proposition 65, California only]:
Small quantities 鈥? less than 100 ppm (parts per million) 鈥? of impurities, including bromates, may be
found in all chlorinating products, including this product. Bromates are derived from bromides, which
are present in sodium chloride (table salt) from which chlorine is manufactured. Additional small
quantities of bromates may be generated during the disinfection process. Bromates are known by the
State of California to cause cancer when administered by the oral (drinking or ingesting) route. Read
and follow label directions and use care when handling or using this product. The US Environmental
Protection Agency has established a maximum contaminant level (MCL) for bromates in drinking
water at 10 ppb (parts per billion). Application of this product in accordance with label directions at
use dilution will not exceed this level.
This warning is provided pursuant to Proposition 65, the Safe Drinking Water and Toxic Enforc ement
act of 1986, Chapter 6.6 of the California Health and Safety Code, which requires the Governor of
California to publish a list of chemicals 鈥渒nown to the state to cause cancer or reproductive toxicity.鈥?
This list is compiled in accordance with the procedures established under the proposition, and can be
obtained on the internet from California鈥檚 Office of Environmental Health Hazard Assessment at
http://www.oehha.ca.gov. There are over 700 chemical substances on this list.

GENERAL PRECAUTIONS FOR SAFE USE AND HANDLING
Mix only with water. Do not mix with other chemicals. Use clean, dry utensils when mixing. Do not add this
product to any dispensing device containing remnants of other products. A violent reaction or explosion may
result when chemicals are mixed. Do not contaminate with moisture, other chemicals, or human wastes.
PERSONAL PROTECTION AND HYGIENE
Wear goggles or face shield and rubber gloves when handling. Avoid breathing dust. Remove and wash
contaminated clothing before reuse. Wash hands after handling.
CLEAN-UP OF SPILLS
Granules should be kept in tightly closed container in a cool, dry, ventilated area. Spilled materials should be
picked up and placed in a dry container. If granules are contaminated by water or other chemicals, or human
waste, place in bucket with lots of clean water. Dissolved granules may be used on-site in pool or spa for
disinfection or disposed of in an approved landfill. Small quantities of granules or solution made from granules
may be discharged into a sanitary sewer. Granules must be disposed of in accordance with Federal, State,
and/or local laws and regulations. Read the label for additional information. Contact HASA, Inc. for guidance.
FIRST AID
Eye Contact: Flush with water. Remove contact lenses [if applicable]. Hold eyelids open.
Continue flushing with water for 15 minutes. Get prompt medical attention.
