Health hazards

IDENTIFICATION HMIS Classification A. CHRONIC HAZARDS: Emergency Overview:

Principle Routes of Exposure

Inhalation PPE GHS WHMIS Inhalation: Dusts may irritate the nose, throat, and respiratory tract by mechanical abrasion. Use of natural sand and gravel for construction purposes is not believed to cause additional acute toxic effects. However, repeated overexposure to very high levels of respirable crystalline silica (quartz, cristobalite, tridymite) for periods as short as six months have caused Contains crystalline silica acute silicosis. Acute silicosis is a rapidly progressive, incurable lung disease that is typically fatal. Symptoms include (but are not limited to); shortness of breath, cough, fever, weight loss, and chest pain. B. SUBCHRONIC AND CHRONIC HEALTH EFFECTS: Pulmonary Diseases: Excessive exposure to particulates (dust) over an extended period of time may result in the development of silicosis and other pulmonary diseases. Carcinogenicity: The classifications below are based on experimental studies with animals and epidemiologic studies of workers exposed to respirable crystalline silica. IARC: classified respirable crystalline silica (quartz) as Group 1, a known carcinogen in humans. NTP: classifies as human carcinogen ACGIH: classified as suspect human carcinogen NIOSH: classified as a potential occupational carcinogen California Proposition 65 Warning: This product will expose you to respirable crystalline silica which is “known in the State of California to cause cancer and to other substances which are known to the State of California to cause cancer, birth defects and other reproductive harm.” 1

WHMIS Classification

Products containing quartz (crystalline Silica) are typically classified as Division 2 A (very toxic) if the chemical has been shown to be carcinogenic, mutagenic (to reproductive cells), reproductive toxic, sensitizer (to respiratory tract or chronic (long-term) toxicity (at low doses).

Medical Conditions Generally Aggravated by Exposure

Excessive dust exposure may aggravate any existing respiratory disorders or diseases. Possible complications of allergies resulting in irritation to skin, eyes and respiratory passage may occur from excessive exposure to dusts. D. ACUTE HAZARDS: Eye Contact Direct contact with dust may cause irritation by mechanical abrasion. Skin Contact Direct contact may cause irritation by mechanical abrasion. Ingestion Expected to be practically non-toxic. Ingestion of large amounts may cause gastrointestinal irritation and blockage. Dusts may irritate the nose, throat, and respiratory tract by mechanical abrasion. Coughing, sneezing, and shortness of breath may occur following exposures in Inhalation excess of appropriate exposure limits. Use of natural sand and gravel for construction purposes is not believed to cause additional acute toxic effects. However, repeated overexposure to very high levels of respirable crystalline silica (quartz, cristobalite, tridymite) for periods as short as six months have caused acute silicosis. Acute silicosis is a rapidly progressive, incurable lung disease that is typically fatal. Symptoms include (but are not limited to); shortness of breath, cough, fever, weight loss, and chest pain.
