SECTION 2: Hazards identification

OSHA EMERGENCY OVERVIEW: No unusual conditions are expected from this product. Inhalation of dusts produced during cutting, sanding or grinding of this product may cause irritation of the respiratory tract.

Principle Routes of Exposure

Inhalation, skin contact, eye contact, ingestion

Potential health effects

Dust from this product may cause slight irritation to the eyes including redness, tearing and blurred vision. Such exposures require immediate first aid (see Section 4) and may require medical attention to prevent damage to the eye. EYES: Dust from this product may cause slight irritation to the eyes including redness, blurred vision and tearing. SKIN: Dust from this product may cause itching, rash and short- term irritation. INGESTION: Ingestion of this product may produce gastrointestinal irritation and disturbances; however, ingestion of this product is unlikely. INHALATION: Dusts from this product may cause irritation of the nose, throat and respiratory tract. This product contains crystalline silica. Prolonged and repeated inhalation of respirable crystalline silica may cause a chronic lung disease called silicosis. This disease is characterized by fibrosis and scarring of the lung tissue which can result in a decrease in lung function, breathlessness, wheezing, coughing and sputum production. Short- term overexposure to extremely high concentrations of respirable crystalline silica can produce acute silicosis. Acute silicosis is a disease that can rapidly progress within months of initial overexposure and reportedly has caused death within 1 to 2 years.

Acute Health Hazards

Irritation, itching, coughing, wheezing

Health hazards

Silicosis as a result of extremely high concentration exposures

Medical Conditions Generally Aggravated by Exposure

Chronic respiratory or skin conditions may temporarily worsen from exposure to dust from this product. CARCINOGENICITY: General Product Information CRYSTALLINE SILICA: The International Agency for Research on Cancer (IARC) recently reviewed existing epidemiological data and concluded that crystalline silica inhaled in the form of quartz from occupational sources is a known human carcinogen (Group 1). In making the assessment, the IARC noted that carcinogenicity was not detected in all industrial circumstances studied. However, IARC reported that a majority of studies indicated an elevated mortality for lung cancer among silica-exposed workers. IARC noted that increased rates of lung cancer were reported among some workers in ore mines, quarries, foundries, ceramics, granite and stone cutting industries. The workers in some of these occupational studies were exposed to other potential respiratory carcinogens such as arsenic, radon, diesel exhaust, polycyclic aromatic hydrocarbons or cadmium. The IARC reviewed animal studies and concluded that there is sufficient evidence in experimental animals for the carcinogenicity of quartz. Silica-crystalline quartz has resulted in liver, blood, and lung tumors in rats by inhalation, intraperitoneal and intravenous injection, intratracheal and intrapleural administration. Component Carcinogenicity ACGIH, IARC, OSHA, and NTP carcinogen lists have been checked for those components with CAS registry numbers. Iron oxide (1309-37-1) ACGIH: A4 - Not Classifiable as a Human Carcinogen (dust and fume, as Fe) IARC: Supplement 7, 1987; Monograph 1, 1972 (Group 3 (not classifiable)) Quartz (14808-60-7) ACGIH: A2 - Suspected Human Carcinogen NTP: Known Carcinogen (Select Carcinogen) IARC: Monograph 68, 1997; (inhaled in the form of quartz or cristobalite from occupational sources) (Group 1 (carcinogenic to humans))
