California Prop 65 Labels that warn of exposure to wood dust. These are 1" x 2" product warning labels that comply with the California State regulations from the required changes needed for August 30th 2018. There are 500 labels on each roll, however, we do add a few extra stickers to help out for specific projects that require an exact amount. Warning: Drilling, sawing, sanding, or machining wood products can expose you to wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask or other personal protection. For more information, visit www.P65Warnings.ca.gov. These prop 65 labels are in English only with black font which is a compliant 8 point font. We create the labels on a semi-gloss paper with permanent adhesive backing. The adhesive is also considered cold temp. This means that they can hold up in freezers and extremely cold temperatures down to negative 65 degrees. They can also withstand very warm climates. All our labels are produced at InStockLabels.com in Salt Lake City, Utah.
