Potential health effects

NOTE: Potential health effects may vary depending upon the duration and degree of exposure. To reduce or eliminate health hazards associated with this product, use exposure controls or personal protection methods as described in Section 12. EYE CONTACT (Acute/Chronic) Exposure to airborne dust may cause immediate or delayed irritation or inflammation of the cornea. Eye contact by larger amounts of dry powder or splashes of wet Concrete Mix may cause effects ranging from moderate eye irritation to chemical burns and blindness. SKIN CONTACT (Acute) Exposure to dry Concrete Mix may cause drying of the skin with consequent mild irritation or more significant effects attributable to aggravation of other conditions. Discomfort or pain cannot be relied upon to alert a person to a hazardous skin exposure. (Chronic) Dry Concrete Mix coming in contact with wet skin or exposure to wet Concrete Mix may cause more severe skin effects, including thickening, cracking or fissuring of the skin. Prolonged exposure can cause severe skin damage in the form of chemical (caustic) burns. (Acute/Chronic) Some individuals may exhibit an allergic response upon exposure to Concrete Mix. The response may appear in a variety of forms ranging from a mild rash to severe skin ulcers. INHALATION (Acute) Exposure to Concrete Mix may cause irritation to the moist mucous membranes of the nose, throat and upper respiratory system. Pre-existing upper respiratory and lung diseases may be aggravated by inhalation. (Chronic) Inhalation exposure to free crystalline silica may cause delayed lung injury including silicosis, a disabling and potentially fatal lung disease, and/or cause or aggravate other lung diseases or conditions. INGESTION (Acute/Chronic) Internal discomfort or ill effects are possible if large quantities are swallowed. CARCINOGENIC POTENTIAL
