NFPA Ratings
0 FLAMMABILITY 0 Fire = 0 2 0 REACTIVITY 0 Reactivity = 0 EMERGENCY OVERVIEW: This product is a brown granular powder. A single short term exposure is not likely to cause serious harm. However, exposure of sufficient duration to wet mixture can cause serious, potentially irreversible tissue (skin or eye) destruction in the form of chemical (caustic) burns. The same type of tissue destruction can occur if wet or moist areas of the body are exposed for sufficient duration to dry product. SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: This product can damage skin, eyes, mucous membranes, and other contaminated tissue. INHALATION: Exposure to this product may cause irritation to the moist mucous membranes of the nose, throat, and upper respiratory system. It may also aggravate other lung conditions. Potential health effects of inhalation are as follows: Silicosis – Respirable crystalline silica (quartz) can cause silicosis, a fibrosis (scarring) of the lungs. Silicosis may be progressive: it may lead to disability and death. Lung Cancer – Crystalline silica (quartz) inhaled is classified by IARC as a carcinogen. Tuberculosis – Silicosis increases the risk of Tuberculosis. Autoimmune and Chronic Kidney Disease – Some studies show excess numbers of cases of scleroderma, connective tissue disorders, lupus, rheumatoid arthritis, chronic kidney diseases and end-stage kidney disease in workers exposed to respirable crystalline silica. Non-Malignant Respiratory diseases (other than Silicosis) – Some studies show an increased incidence in chronic bronchitis and emphysema in workers exposed to respirable crystalline silica. CONTACT WITH SKIN: Discomfort or pain cannot be relied upon to alert a person to a hazardous skin exposure. Consequently, the only effective means of avoiding skin injury or illness involves minimizing skin contact, particularly contact with wet product. Exposed persons may not feel discomfort until hours after the exposure has ended and significant injury has occurred. Exposure to dry material may cause drying of the skin with consequent mild irritation or more significant effects attributable to aggravation of other conditions. Dry material contacting wet skin or exposure to moist or wet cement may cause more severe skin damage in the form of (caustic) chemical burns. Some individuals may exhibit an allergic response upon exposure to this material. The response may appear in a variety of forms ranging from a mild rash to severe skin ulcers. Persons already sensitized may react to their first contact with the product. CONTACT WITH EYES: Exposure to airborne dust may cause immediate or delayed irritation or inflammation. Eye contact by larger amounts of dry powder or splashes of wet material may cause effects ranging from moderate eye irritation to chemical burns and blindness. Such exposures require immediate first aid (see section 4) and medical attention to prevent significant damage to the eye. INGESTION: Though ingestion is not anticipated to be a significant route of over-exposure to this product, ingestion of large amounts can be harmful and requires immediate medical attention. INJECTION: Though injection is not anticipated to be a significant route of over-exposure to this product. HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. ACUTE: Contact with this solution may cause irritation of the eyes, skin, mucous membranes, and any other exposed tissue. If inhaled, irritation of the respiratory system may occur, with coughing, and breathing difficulty. CHRONIC: Repeated skin contact with this product may result in dermatitis (inflammation and reddening of the skin). Prolonged or repeated exposure may cause liver and kidney damage.
