present below the threshold for labeling, an ingredient may not be available for exposure, or the data may not be
relevant to the material as a whole.
11.1. Information on Toxicological effects
Signs and Symptoms of Exposure
Based on test data and/or information on the components, this material may produce the following health effects:
Inhalation:
Dust from grinding, sanding or machining may cause irritation of the respiratory system. Signs/symptoms may include cough,
sneezing, nasal discharge, headache, hoarseness, and nose and throat pain.
Skin Contact:
Mechanical Skin irritation: Signs/symptoms may include abrasion, redness, pain, and itching.
Eye Contact:
Mechanical eye irritation: Signs/symptoms may include pain, redness, tearing and corneal abrasion.
Dust created by grinding, sanding, or machining may cause eye irritation. Signs/symptoms may include redness, swelling,
pain, tearing, and blurred or hazy vision.
Ingestion:
No health effects are expected.
Carcinogenicity:

Additional Information:
This document covers only the 3M product. For complete assessment, when determining the degree of hazard, the material
being abraded must also be considered.
This product contains titanium dioxide and quartz (crystalline) silica. Cancer of the lungs has been associated with inhalation
of high levels of titanium dioxide in animal studies, and occupational exposure to inhaled quartz silica has been associated
with silicosis and lung cancer. No exposure to titanium dioxide or quartz silica is expected during the normal handling and
use of this product. Titanium dioxide and quartz silica were not detected when air sampling was conducted during simulated
use of similar products containing these substances. Therefore, the health effects associated with titanium dioxide and quartz
(crystalline) silica are not expected during the normal use of this product.
Toxicological Data
If a component is disclosed in section 3 but does not appear in a table below, either no data are available for that endpoint or
the data are not sufficient for classification.
