Section 2
SECTION 2: Hazards identification
Emergency Overview: Color: Tan Form: Powder Odor: Odorless Nonflammable
Contains
SUSPECT CANCER HAZARD. (Attapulgite contains naturally occurring crystalline silica.) However, in reviewing this material, IARC has determined that there is inadequate evidence of carcinogenicity to humans and experimental animals (Group 3). Prolonged or repeated exposure effects: Inhalation of dust may cause a disabling, progressive pulmonary fibrosis.
Potential health effects
Inhalation: May cause irritation of the respiratory tract. Prolonged or repeated exposure causes lung damage. Ingestion: No adverse health effects are expected from swallowing. Skin Contact: May cause skin irritation. Eye Contact: Dust may cause irritation and inflammation. Carcinogenicity: Ingredient Weight in NTP IARC
Health hazards
NIOSH has studied the exposure effects of Attapulgite, which contains crystalline silica, on pulmonary function and has determined that there is no evidence of significant respiratory morbidity. Prolonged or repeated inhalation of crystalline silica dust may cause disabling, progressive pulmonary fibrosis (silicosis). May cause chronic bronchitis.
Medical Conditions Generally Aggravated by Exposure
Pulmonary disorders. Allergies.
