SECTION 2: Hazards identification

Principle Routes of Exposure

Inhalation: YES Skin: NOT LIKELY Ingestion: NO Acute: Eye contact Direct contact with dust may cause irritation by mechanical abrasion. Exposure to wet material may be slightly caustic and cause irritation or injury. Skin Contact: Direct contact with dust may cause irritation by mechanical abrasion. Exposure to wet material may be slightly caustic and cause irritation or injury. Skin Absorption: Not expected to be a significant exposure route. Ingestion: If ingested, the material may become slightly caustic and cause tissue irritation. Ingestion of large amounts may cause gastrointestinal irritation and blockage. Inhalation: Dusts may irritate the nose, throat, and respiratory tract. Coughing, sneezing and shortness of breath may occur following exposures in excess of appropriate exposure limits. Chronic: Inhalation: Chronic exposure to respirable dust in excess of appropriate exposure limits may cause lung disease. Silicosis may result from excessive exposure to respirable silica dust for prolonged periods. Not all individuals with silicosis will exhibit symptoms. Silicosis is progressive and symptoms can appear at any time, even after exposure has ceased. Symptoms may include shortness of breath, coughing or right heart enlargement and/or failure. Persons with silicosis have an increased risk of pulmonary tuberculosis infection. Tobacco smoking may increase the risk of developing lung disorders, including emphysema and lung cancer. Carcinogenicity

Medical Conditions Generally Aggravated by Exposure

Inhaling respirable dust may aggravate existing respiratory system disease(s) and/or dysfunctions such as emphysema or asthma. Exposure may aggravate existing skin and/or eye conditions.
