The chemical agents used in the different processes include lead (7439921) and lead alloys with tin (7440315) and antimony (7440360) for type; steel, copper (7440508), aluminum (7429905), zinc (7440666), magnesium (7439954), chromium (7440473) and brass for plates; mineral acids and salts for etching, carbon black and pigments for inks, organic and petroleum solvents for thinning, oils and greases for ink thickening; polymers, gelatin, and cellulosic esters for photographic films and materials; photographic emulsions; glues, varnishes, resins and paints. Many of these substances are toxic, flammable, and potential hazards, and may contaminate the workers' skin, clothing, and surroundings while washing, handling and during accidental spilling. Carbon black may enter the respiratory system and other parts of the workers' bodies. Excessive noise commonly occurs and can cause permanent hearing damage. Press rooms and other printing plant operations develop noise at 90 decibel (A) levels. Other safety and health hazards are also discussed. (Contract No. 210-77-0120)
