Lafarge Hydrated Lime

SECTION 2: Hazards identification

Corrosive - Causes severe burns. Toxic - Harmful by inhalation. Respiratory Eye (Contains crystalline silica) to prevent exposure to wet or dry product. Protection mL Use proper engineering controls, work practices, and personal protective equipment Waterproof Read MSDS for details. Gloves. Boots Page 1 of 6 (continued) Emergency Overview: Hydrated lime is a granular, white or grey, odorless powder. It is not combustible or explosive, A single, short-term exposure to the dry powder presents little or no hazard. Exposure of sufficient duration to hydrated lime can cause serious, potentially irreversible tissue (skin, eye, respiratory tract) damage due to chemical (caustic) burns, including third degree burns.

Potential health effects

Eye Contact: Airborne dust may cause immediate or delayed irritation or inflammation. Eye contact with large amounts of dry powder or with wet hydrated lime can cause moderate eye irritation, chemical burns and blindness. Eye exposures require immediate first aid and medical attention to prevent significant damage to the eye. ‘Skin Contact: Hydrated lime may cause dry skin, discomfort, irritation, and severe burns. jurns: Exposure of sufficient duration to wet hydrated lime, or to dry hydrated lime on moist areas of the body, can cause serious, potentially irreversible damage to skin, eye, respiratory and digestive tracts due to chemical (caustic) burns, including third degree burns. A skin exposure may be hazardous even if there is no pain or discomfort. Inhalation (acute): Breathing dust may cause nose, throat or lung irritation, including choking, depending on the degree of exposure. Inhalation of high levels of dust can cause chemical burns to the nose, throat and lungs. Inhalation (chronic): Risk of injury depends on duration and level of expasure. Silicosis: This product contains crystalline silica. Prolonged or repeated inhalation of respirable crystalline silica from this product can cause silicosis, a seriously disabling and fatal lung disease, See Note to Physicians in Section 4 for further information. Hydrated lime is not listed as a carcinogen by IARC or NTP; however, hydrated lime contains trace amounts of crystalline silica which is classified by IARC and NTP as known human carcinogen. Autoimmune Some studies show that exposure to respirable crystalline silica (without silicosis) or Disease: that the disease silicosis may be associated with the increased incidence of several autoimmune disorders such as scleroderma (thickening of the skin), systemic lupus erythematosus, rheumatoid arthritis and diseases affecting the kidneys. Tuberculosis: Silicosis increases the risk of tuberculosis. Renal Disease: Some studies show an increased incidence of chronic kidney disease and end-stage renal disease in workers exposed to respirable crystalline silica. Ingestion: Do not ingest hydrated lime. Although ingestion of small quantities of hydrated lime is not known to be harmful, large quantities can cause chemical burns in the mouth, throat, stomach, and digestive tract. Medical Conditions Individuals with lung disease (e.g. bronchitis, emphysema, COPD, pulmonary Aggravated by Exposure: disease) can be aggravated by exposure. Page 2 of 6
