File compilation with a handwritten cover sheet, a 1987 Cyprus letter sending talc Material Safety Data Sheets (Mistron Vapor, Beaverwhite 325) to UCAR Emulsion Systems, and an undated United Sierra bulletin (FP-13) on replacing asbestos-contaminated magnesium silicate extenders with platy talc in paints. The letter carries handwritten margin notes about respirable dust limits and the talc's OSHA hazard status. The MSDS pages describe talc composition, a respirable dust threshold limit value, and possible pneumoconiosis from prolonged exposure to talc-containing dusts.
