SURVEY Georgia Pacific Corporation Gypsum Division - Acme Plant Quanan, Texas On September 8, 1972, an industrial hygiene survey was performed by Jerry F. Lsuderd- Assistant Engineer, Industrial.Hygiene Program, Texas State Department of Health f a r the purpose of detecting the exposure levels of employees in the Joint System Departs to airborne esbestos fibers. The survey w* requested by Mr. Bill Howard Safecv Superintendent, through the Texas Health Department, Air Pollution Control/Program. 1^2jfCir U n ? cl-BTk* Supervisor of the Joint System Department, and other employees ga cordial assistance in conducting the survey. 7 S The Joint -System Department mixes and packages a compound, CP Triple Duty Joint Compound, "which is used in construction to smooth joints between wall boards.
