How many chemicals require the prop 65 warning?
When Prop 65 went into effect in 1987, there were about 30 chemicals listed. Now there are nearly 900. No manufacturer can afford to routinely test for that many chemicals. In addition, some “naturally occurring” chemicals and substances are included on the list. For example, in 2009 wood dust was listed. In this case, the American Home Furnishings Alliance was able to obtain a ruling from the California Attorney General’s office exempting finished furniture from the warning requirement, as long as the product does not require the consumer to perform any type of assembly activity – such as “sawing, sanding or other actions that would produce wood dust.” However, to be safe, some manufacturers provide the warning anyway, even if consumers are simply required to screw in the legs of a table or chair.
