11. Toxicological Information
EFFECT OF OVEREXPOSURE - INHALATION: Prolonged, repeated, or high exposures may cause irritation to the respiratory tract
(nose, mouth, mucous membranes). Dust from dry sanding may cause eye, skin, nose, throat and respiratory tract irritation.
EFFECT OF OVEREXPOSURE - SKIN CONTACT: Under normal use conditions, this product is not expected to cause adverse
health effects. Prolonged or repeated contact with skin may cause mild irritation.
EFFECT OF OVEREXPOSURE - EYE CONTACT: Under normal use conditions, this product is not expected to cause adverse
health effects. Direct eye contact may cause irritation. May cause eye irritation.
EFFECT OF OVEREXPOSURE - INGESTION: Under normal use conditions, this product is not expected to cause adverse health
effects. Single dose oral toxicity is very low. Amounts ingested incidental to industrial handling are not likely to cause injury; however,
ingestion of large amounts may cause injury. Ingestion may result in obstruction when material hardens.
CARCINOGENICITY: No Information
EFFECT OF OVEREXPOSURE - CHRONIC HAZARDS: The International Agency for Research on Cancer (IARC) has determined
that crystalline silica in the form of quartz or cristobalite that is inhaled from occupational sources is carcinogenic to humans (Group 1-
carcinogenic to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (published in June 1997) in
conjunction with the use of these materials. The National Toxicology Program (NTP) classifies respirable crystalline silica as "known
to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial
Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (Group A2). Breathing dust containing
respirable crystalline silica may not cause noticeable injury or illness even though permanent lung damage may be occurring.
Inhalation of dust may have the following serious chronic health effects: Excessive inhalation of respirable dust can cause
pneumoconiosis, a respiratory disease, which can result in delayed, progressive, disabling and sometimes fatal lung injury.
Symptoms include cough, shortness of breath, wheezing, non-specific chest illness and reduced pulmonary function. Smoking
exacerbates this disease. Individuals with pneumoconiosis are predisposed to develop tuberculosis. There is some evidence that
breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease
endpoints such as scleroderma (an immune system disorder manifested by fibrosis of the lungs, skin and other internal organs) and
kidney disease. Prolonged or repeated inhalation of dust may cause lung damage.
