WARNING: INJURIOUS TO EYES: CAUSES SKIN IRRITATION: READ THIS WARNING BEFORE USING: CONTAINS PORTLAND CEMENT.
Contact with wet, unhardened concrete, mortar, cement, or cement mixtures can cause skin irritation, severe chemical burns or serious eye damage. Avoid contact with eyes
and skin. Wear waterproof gloves, a fully buttoned, long-sleeve shirt, full length trousers and tight-fitting eye protection when working with these materials. If you have to stand
in wet concrete, use waterproof boots that are tight at the top and high enough to keep concrete from flowing into them. If you are finishing concrete, wear kneepads to protect
knees. Wash wet concrete, mortar, cement or cement mixtures from your skin with fresh, clean water immediately after contact. Indirect contact through your clothing can be as
serious as direct contact, so promptly rinse wet concrete, mortar, cement or cement mixtures from clothing. Seek immediate medical attention if you have persistent or severe
discomfort. In case of eye contact, flush with plenty of water for at least 15 minutes. Consult a physician immediately. KEEP OUT OF REACH OF CHILDREN. USER AGREES
TO CONVEY THIS WARNING TO ALL PERSONS WHOM MAY USE OR COME IN CONTACT WITH WET (UNHARDENED) CONCRETE, MORTAR, AND CEMENT OR
CEMENT MIXTURES.
CRYSTALLINE SILICA CARCINOGENIC POTENTIAL: Concrete frequently contains crystalline silica in concentrations greater than 0.1 percent, principally contributed by the
aggregates. Respirable crystalline silica is classified by the International Agency for Research on Cancer as a known human carcinogen and by the National Toxicology Program
as "reasonably anticipated to be a carcinogen". Crystalline silica in wet concrete is not respirable and does not pose a hazard when the concrete is in its plastic or unhardened
state. Once concrete has hardened, airborne dust generated by grinding, sawing, drilling, breaking, etc., can lead to potentially hazardous exposures to workers and appropriate
respiratory protection precautions should be taken.
