TOXICOLOGICAL INFORMATION

The information below may not be consistent with the material classification in Section 2 if specific ingredient __________________________________________________________________________________________ Page 4 of 8 4600-NID NON-INDICATING DESICCANT BAG 05/21/18 classifications are mandated by a competent authority. In addition, toxicological data on ingredients may not be reflected in the material classification and/or the signs and symptoms of exposure, because an ingredient may be 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: May be harmful if inhaled. Skin Contact: Contact with the skin during product use is not expected to result in significant irritation. Eye Contact: Contact with the eyes during product use is not expected to result in significant irritation. Ingestion: No known health effects.
