Contains: less than 1% Silica, crystalline quartz - CAS# 14808-60-7
The International Agency for Research on Cancer (IARC) has stated that there is sufficient evidence of carcinogenicity of crystalline silica to
human beings. It was noted that carcinogenicity was not detected in all industrial circumstances studied. The NTP's Sixth Annual Report on
Carcinogens include respirable crystalline silica. The Hazard Communication Standard (29CFR 1910.1200) requires that any material containing
over 0.1% of a substance reported as a carcinogen in an IARC monograph or the most recent NTP Annual Report on Carcinogens must be
identified as a carcinogen. These identifications are for hazard communications only and do not serve as assessments of carcinogenic risk.
Crystalline silica is known to cause silicosis. At dust levels below the recommended PEL exposure to the crystalline silica contained in this
product should not present a health hazard.
NTP - Yes (respirable)
Section 11 Toxicological Information
Reporting Requirements: The components of this product are not subject to the reporting requirements of U.S. Superfund Amendments and
Reauthorization Act (SARA), Title III, Sections 302, 304, and 313.
Slightly soluble in strongly alkaline solution
Marine Pollutant: No (per 49 CFR 172.101 appendix B)
Section 13 Disposal Considerations
Waste disposal must be in accordance with U.S. Federal, State and local regulation or those of Canada and its Provinces. This product, if
unaltered by use, may be disposed of by treatment at a permitted facility or as advised by your local hazardous regulatory authority.
NTP: Amorphous silica is generally less toxic than crystalline silica. Since it has greater water solubility, it is cleared more rapidly from the body.
Effects observed after inhalation of amorphous silica were milder than those observed for crystalline silica. The IARC considered the available
data inadequate for determining the carcinogenic potential of amorphous silica.
