chances of getting cancer by no more than 1 case in 100,000 individuals so exposed. With respect to reproductive
toxicants, the "no significant risk" level is defined as the level of exposure which, even if multiplied by 1,000, will not
produce birth defects or other reproductive harm. In other words, the level of exposure is below the "no observable
effect level," divided by 1,000. (The "no observable effect level" is the highest dose level which has not been associated
with observable reproductive harm in humans or test animals.) Proposition 65 does not clarify whether exposure is to
be measured only in normal operation, or in the event of misuse such as intentionally damaging, incinerating or
consuming an Ambient Weather Product or component and Ambient Weather has not attempted to evaluate the level of
exposure.
A Proposition 65 warning means one of two things: (1) the business has evaluated the exposure and has concluded that
it exceeds the "no significant risk level"; or (2) the business has chosen to provide a warning simply based on its
knowledge about the presence of a listed chemical without attempting to evaluate the exposure. The California
government has itself clarified that "The fact that a product bears a Proposition 65 warning does not mean by itself that
the product is unsafe." The government has also explained, "You could think of Proposition 65 more as a 'right to know'
law than a pure product safety law."
While using Ambient Weather Products as intended, we believe any potential exposure would be negligible or
well within the "no significant risk" range. However, to ensure compliance with California law and our
customers' right to know, we have elected to place the Proposition 65 warning signs on Ambient Weather
Products.
