CHRONIC EXPOSURE: Repeated or prolonged inhalation of air-born dust of this material may cause scarring of the lungs (pulmonary fibrosis), with shortness of breath, chrome cough, and respiratory assisted heart failure. Prolonged exposure to talc can produce a mild symptomatic pneumoconiosis. RESPIRABLE QUARTZ A CARCINOGEN ACUTE EXPOSURE: Exposure to high concentrations of respirable crystalline silica may cause physical discomfort of the upper respirator tract. CHRONIC EXPOSURE: Inhalation of very high concentrations of finely dividcd-respirable-crystalline silica dust may cause a rapidly developing silicosis. Smoking can increase the risk of injury. FIRST AID: Remove from exposure area to fresh air. If breathing has stopped, perform artificial respiration, and get medical attention immediately. Keep person warm and at rest. Treat symptomatically and supportively. SKIN CONTACT ****************************** TALC ACUTE EXPOSURE: Direct contact may cause slight dryness, or may cause mild irritation if an allergic predisposition exists. CHRONIC EXPOSURE: Prolonged contact may cause slight dryness of the skin, or may cause mild irritation if an allergic predisposition exists. FIRST AID: Apply common skin moisturizers to relieve dryness. Irritations are uncommon; however, if irritation or redness develops, seek medical attention. Broken skin can be cleansed with mild soap and water. EYE CONTACT ****************************** TALC ACUTE EXPOSURE: Direct contact with dust may cause mechanical irritation of the eyes. CHRONIC EXPOSURE: Repeated exposure may cause conjunctival inflammation. FIRST AID: Wash eyes with large amounts of water or normal saline solution. If irritation or redness develops, seek medical attention. INGESTION TALC ************* ACUTE EXPOSURE: This material is considered to be harmless and inert when ingested. CHRONIC EXPOSURE: Repeated ingestion of large doses of talc for 13 and 10 successive days by rabbits and mice, respectively, revealed negative teratogenic and carcinogenic results. FIRST AID: Treat symptomatically and supportively. If vomiting occurs, keep head lower than hips to prevent aspiration. ANTIDOTE: No specific antidote. Treat symptomatically and supportively. 3 LUZ00000053 STORAGE AND DISPOSAL Talc is not considered a hazardous waste by RCRA criteria (40 CFR 261). Observe all federal, state and local regulations when storing or disposing of this substance. For assistance, contact the district director of the Environmental Protection Agency. STORAGE: Preserve in sealed containers to prevent dispersion of dust in air. WASTE DISPOSAL: Dry material can be landfilled. Wet material can be sewered, if quantities are small and diluted enough that slurries or gels will not cause drain system blockage. Prevent dispersion of dust in air. CONDITIONS TO AVOID ACCIDENTAL SPILLS OCCUPATIONAL SPILL: For large spills, shovel or sweep up (while keeping dispersion of dust in air to a minimum) and place into suitable sealed containers for reclamation or later disposal. Residue should be cleaned up using a high-efficiency particulate filter vacuum. The use of water washdown is not recommended. Wet material can cause a surface used for walking to become extremely slippery. PROTECTIVE EQUIPMENT VENTILATION: Provide local exhaust or process enclosure ventilation to meet published exposure limits. RESPIRATOR: The following maximum-use concentrations and respirators are recommendations by the U.S. Department of Health and Human Services; NIOSH Pocket Guide to Chemical Hazards; NIOSH criteria documents; or by the U.S. Department of Labor, 29 CFR 1910 subpart Z. The specific respirator selected must be based on contamination levels found in the work place, must not exceed the working limits of the respirator, and be jointly approved by the National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA).

CLOTHING: Protective clothing is not required. GLOVES: Protective gloves are not required, but may be worn to prevent skin dryness or irritation due to skin allergy. EYE PROTECTION: Employees should wear dust-resistant safety goggles to prevent eye contact with bulk quantities or high concentrations of air-born dust of this substance. EMERGENCY EYE WASH: Where there is a possibility that an employee's eyes may be exposed to bulk quantities or high concentrations of air-born dust of this substance, the employer should provide an eye wash fountain within the immediate work area for emergency use.
