The ratings in this publication are subject to the following conditions:

  1. Product ratings are based upon available information. Products may contain ingredients or contaminants unknown to Metro, King County, or Thurston County whose presence, if known, would change the product’s ratings.
  2. Safety of a product depends to a great extent upon how it is used. Because individuals may exercise different safety precautions, a lower hazard rating is not a guarantee of a product’s safety, just as a higher hazard rating does not necessarily imply that use will cause harm or damage.
  3. These ratings are presented as an informational service. A lower hazard rating does not constitute an endorsement of a particular product. Metro, King County, and Thurston County make no guarantees as to the safety or efficacy of any product and assume no responsibility or liability for any injury or damage that may result from using any such product.
