SECTION 2: Hazards identification

Emergency Overview Color: Grey Physical State: Cured concrete Odor: Slight cement odor Hazards of product: Toxic – Harmful by inhalation (Contains crystalline silica) Concrete in its intact state will not release airborne dust, but dust can be produced during cutting, grinding, drilling, and other machining of the product.

Potential health effects

Eye Contact (acute): Concrete dust may cause immediate or delayed irritation or inflammation. Eye exposures require immediate first aid and medical attention. Direct contact can cause irritation before mechanical abrasion. Skin contact: Cured concrete dust may cause dry skin, discomfort, irritation, severe burns, and dermatitis. Ingestion: Do not ingest concrete. Small quantities not know to be harmful. Ingestion of large amounts may cause gastrointestinal irritation and blockage. Inhalation (general): May result, depending on the degree of the exposure, from exposure to dust generated from cutting, grinding, crushing, or drilling hardened concrete. Inhalation (acute): Breathing dust may cause nose, throat, lung or mucous membrane irritation, including choking. 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 exposure. Silicosis: This product contains crystalline silica. Prolonged or repeated inhalation of respirable crystalline silica from this product can cause silicosis, and other seriously disabling and fatal diseases. Carcinogenicity: Concrete is not listed as a carcinogen by IARC or NTP; however, concrete contains trace amounts of crystalline silica and hexavalent chromium which are classified by IARC and NTP as known human carcinogens. Autoimmune Disease: Some studies show that exposure to respirable crystalline silica (without silicosis) or that the disease silicosis may be associated with the increased incidence of severe autoimmune disorders such as scleroderma (thickening of 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.

Medical Conditions Generally Aggravated by Exposure

Individuals with lung disease (e. g. bronchitis, emphysema, COPD, pulmonary disease) can be aggravated by exposure to concrete dust.
