SECTION 2: Hazards identification

29 CFR 1910.1200) EMERGENCY OVERVIEW: The material is white or tan sand, or ground sand; the ground sand looks like white powder. It has no odor and is not flammable, combustible or explosive. It does not cause burns or severe skin or eye irritation. A single exposure will not result in serious adverse health effects. Crystalline silica is not known to be an environmental hazard. Personal protective equipment – respirator -- is not required unless the concentration of respirable silica dust exceeds applicable occupational exposure levels. Crystalline silica (quartz) is incompatible with hydrofluoric acid, fluorine, chlorine trifluoride or oxygen difluoride. Romanoff International Supply Corporation 9 Deforest Street Amityville New York 11701 USA Phone 1-631-842-2400 , Fax 631-842-0028 OSHA REGULATORY STATUS This material is considered hazardous under the OSHA Hazard Communications Standard (29 CFR 1910.1200).

Potential health effects

The potential health effects are CHRONIC; the route of exposure is INHALATION; the hazards described are associated with respirable crystalline silica dust – respirable dust particles are less than 10 microns in aerodynamic diameter. . 2.3.1. Inhalation: a. Silicosis: The prolonged repeated inhalation of respirable crystalline silica can cause silicosis, a fibrosis (scarring) of the lungs. Silicosis may be progressive; it may lead to disability and death. b. Lung Cancer: Crystalline silica is classified as carcinogenic to humans. c. Tuberculosis: Silicosis increases the risk of tuberculosis. d. Autoimmune and Chronic Kidney Diseases: 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. e. 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. 2.3.2. Eye Contact: Crystalline silica (sand or ground silica) may cause abrasion of the cornea. 2.3.3. Skin Contact: Not applicable. 2.3.4. Ingestion: Not applicable. 2.3.5.

Potential chronic health

The adverse health effects -- silicosis, lung cancer, autoimmune and chronic kidney diseases, tuberculosis, and non-malignant respiratory diseases -- are chronic effects. 2.3.6. Signs and Symptoms of Exposure: Generally, there are no signs or symptoms of exposure to crystalline silica; silicosis may result in shortness of breath, especially upon exertion. See Section 11 for additional information. 2.3.7.

Medical Conditions Generally Aggravated by Exposure

The condition of individuals with lung disease (e.g., bronchitis, emphysema, chronic obstructive pulmonary disease) can be aggravated by exposure. 2.3.8

Environmental effects
