Oil-Dri Sweeping Compound

SECTION 2: Hazards identification

EMERGENCY OVERVIEW This product is a wood dust-sand mixture which will burn under fire conditions. This product contains naturally occurring crystalline silica as quartz. Prolonged overexposure to respirable crystalline silica may cause lung disease (silicosis) and increase the risk of lung cancer. Risk of cancer depends on duration and level of exposure. The physical form of this product is such that no exposure to respirable crystalline silica and wood dust is likely under normal conditions of use, therefore the risk of adverse health effects is minimal.

Health hazards

INGESTION: May cause irritation to the mouth, throat and gastrointestinal tract. May be harmful if swallowed. INHALATION: Inhalation of excessive concentrations of dust may cause irritation of mucous membranes and upper respiratory tract. EYE: Contact may cause mechanical irritation and possible injury. SKIN: May cause mild skin irritation. Prolonged skin contact may cause dermatitis. SENSITIZATION: This product is not expected to cause skin or respiratory sensitization. CHRONIC/CARCINOGENICITY: Inhalation of excessive concentrations of any dust, including this material, may lead to lung injury. This product contains crystalline silica. Excessive inhalation of respirable crystalline silica may cause silicosis, a progressive, disabling and fatal disease of the lung. Symptoms may include cough, shortness of breath, wheezing and reduced pulmonary function. The International Agency for Research on Cancer (IARC), in Monograph 68 has concluded that crystalline silica inhaled in the form of quartz or cristobalite, from occupational sources is carcinogenic to humans (Group 1). However, in making the overall evaluation, the Working Group noted that carcinogenicity was not detected in all industrial circumstances studied. Carcinogenicity may be dependent on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution of its polymorphs. The National Toxicology Program (NTP) classifies crystalline silica as a "known human carcinogen." Wood dust has been classified by the International Agency for Research on Cancer (IARC) as "carcinogenic to humans" (Group 1) and "known to be a human carcinogen" by the National Toxicology Program (NTP). This classification is based primarily on increased risk in the occurrence of adenocarcinomas of the nasal cavities and paranasal sinuses associated with exposure to wood dust. The physical form of this product is such that no exposure to respirable crystalline silica and wood dust is likely under normal conditions of use, therefore the risk of adverse health effects is minimal.
