FILE NAME: US Gypsum (USG) DATE: November 1973 DOC#: USG125 DOCUMENT DESCRIPTION: 1973 Report of Special Task Force on Joint Treatment Compound ; PLAINTIFFS EXHIBIT 1633(41 REPORT OF SPECIAL TASK FORCE ON JOINT TRSATHEi-.T COMPOUND fC* / 2 This is the first report on the proceedings and status of the work being done by the Special Committee on Asbestos in Joint Compound. As you will recall, a recommendation was made to the Gypsum Association that it involve itself in the assessment of release of asbestos fibers during the use of the joint treat ment products by the customer. This recommendation was based on the stringent regulations of the Occupational Safety and Health Act. At the annual meeting, all committees and the Board supported a basic program and funds were appropriated to conduct a field test program to determine what level of asbestos fibers are re leased in mixing and sanding operations when using joint compound products. It wes further stipulated that an independent laboratory would serve to monitor this type of program in order to minimize cost due to duplicate individual efforts by the membership. . In May of this year, representatives from the Gypsum Association met with OSHA representatives in Washington to. discuss regulations pertaining to asbestos. The two purposes for this meeting were (1) a hope to obtain an interpretation of the law which would precludethe need for placing labels on containers of joint compound if the asbestos fiber environment generated during its normal use would not exceed the OSHA limits, and (2) a variance from the regulations which would eliminate the need for the con tractor to provide monitoring at each job site. Although OSHA was impressed with our interest in our consumers use of the pro duct, they verbally denied any general relief from either the labeling or the monitoring requirement. Subsequent to the meeting with OSHA, a special Association committee was formed from member designates who were skilled in air sampling techniques and evaluations. This committee formulated a test pro gram and selected George D. Clayton and Associates as the independ ent laboratory to do the monitoring for the test. The actual test work was conducted by Gardineer Crywall Company, Aurora, Colorado, and they provided excellent cooperation in order that the monitoring of dust and asbestos fibers could be evaluated. Ten dry powder and ready mix topping grade joint compounds from five manufacturers were delivered to the site by the Association members. Containers were unmarxed except for a code number assigned by the Association's confidential depository. Ten test houses, in close proximity to each other and of relatively comparable size were designated for the test program. One product was assigned for each -- house for the mixing and sanding procedures. i * The mixing tests required about 15 minutes per product and the sanding required an average-of one hour per house; sanding was accomplished in a manner typical of fiat work. or*.tv., r: - 2- A1though a final report has not been submitted by Clayton, there was a special committee meeting held October 3 and a discussion of preliminary results indicated that there might be some area of inconsistency or incompletion of data obtained from this test program. The Committee recommends that certain portions of this program be redone to assure the Association that results which are to be published in the final report are accurate, complete and consistent. The Phase II program has already been established and the Committee is ready to proceed. It is estimated that this phase will cost no more than $2,000 and it is requested that the Board of Directors approve such expenditures. If funds are appropriated, Phase II can complete their work and submit a comprehensive report of findings and recommendations by the end of January 137^. It is not possible as of now to predict if additional testing will be required after Phase l I .
