• Description:
  A walk through survey was conducted at the Cyprus Industrial Minerals Company, Los Angeles, California as part of a study to characterize talc (14807966) used in the United States. Cyprus Mines acquired its present site in 1964. The mill has been in operation since 1919 and graded different blends and grades of talc for use in paints and tile. Nine employees work at the site during two or three shifts per day. Stockpiled talc was fed into the crusher where it was conveyed by elevator to a bin, and then dropped through a Raymond Roller mill before being bagged. If a finer product was required, the talc was also passed through a Raymond Vertical mill before bagging. The employees were potentially exposed to noise and excessive dust. The personnel records at this site included social security numbers, work histories and the lost time accident data back to at least 1964. The authors suggest that an audiometric hearing program should be instituted to determine the effectiveness of the current hearing protection program, and that dust levels in the air be reduced by increasing the exhaust ventilation around the packing machines.
