California Proposition 65
WARNING: Drilling, sawing, sanding or machining wood products, such as firewood, can expose you to wood dust, a substance known to the State of California to cause cancer.
CAUTION: Avoid inhaling wood dust or use a dust mask and other appropriate safeguards for your personal protection.
WARNING: Burning wood in any wood-fueled heating appliance such as a pellet or wood burning stove can cause the formation of creosote, a substance known to the State of California to cause cancer.
CAUTION: To minimize your exposure to potential smoke and creosote, operate only a wood heating appliance that has been EPA Certified and avoid inhaling smoke resulting from the operation of a wood heating appliance. As well, use adequate caution and appropriate protective equipment and clothing when removing ashes from your wood heating appliance and/or cleaning your chimney.
