11. Toxicological Information
Effects of Overexposure - Eye Contact: No Information
Effects of Overexposure - Skin Contact: No Information
Effects of Overexposure - Inhalation: Constituents of this product include crystalline silica dust which, if inhalable, may cause
silicosis, a form of progressive pulmonary fibrosis. Inhalable crystalline silica is listed by IARC as a group I carcinogen (lung) based
on sufficient evidence in occupationally exposed humans and sufficient evidence in animals. Crystalline silica is also listed by the
NTP as a known human carcinogen. Constituents may also contain asbestiform or non-asbestiform tremolite or other silicates as
impurities, and above de minimus exposure to these impurities in inhalable form may be carcinogenic or cause other serious lung
problems.
Effects of Overexposure - Ingestion: No Information
Effects of Overexposure - Chronic Hazards: High concentrations may lead to central nervous system effects (drowsiness, dizziness,
nausea, headaches, paralysis, and blurred vision) and/or damage. Reports have associated repeated and prolonged occupational
overexposure to solvents with permanent brain and nervous system damage.
