A:Answer Hi there - Great question! We comply with all federal, state and international requirements regarding hazardous substances and meet those standards. We also comply with federal and state chemical labeling laws, like California Proposition 65. The presence of a Proposition 65 warning does not necessarily mean the product is unsafe or poses a health risk. Over 800 chemicals are on this list, including wood dust, nickel (found in stainless steel), nicotine, and alcohol. Additionally, even inaccessible parts can cause the warning. We can understand your concern; however, we do not provide detailed information about what causes the Prop 65 warning to apply. Thanks for checking! -Mikayla@GEA
