ITEM 11-61-73 OBSOLETE PUBLICATIONS Mr. Brackett reported that some Association publications were outdated and should be revised or dropped. It was agreed, when possible to include the data in other popular current, publica tions. It was requested that the Promotional Committee, who has ultimate responsibility for the publications, allow the Technical Committee to review them for technical accuracy, as they are indi vidually considered for revision. COMMITTEE ACTION1: A motion was made, second and carried to remove the item from the agenda. ITEM II-62-73 STANDARD FOR DAMAGE RESISTANT WALLS The sense of this item was considered under Item 11-37 " Standards for Durability. - COMMITTEE ACTION: A motion was made, seconded and carried to remove this item from the agenda. ITEM 11-63-73 ASBESTOS FIBER IN JOINT COMPOUND It had been recommended that the Association begin an in vestigative program to determine the extend of hazards to health and safety of use of asbestos in joint compounds, as a result of sanding and dry mixing operations. OSHA regulations are strict concerning asbestos and there could be problems within the gypsum industry as a result of inhalation of asbestos fibers present in dust environments. The committee proposed the following initial considerations: 1. The member companies should pool information they have on the subject. 2. It is necessary to determine ranges of hazards. 3. The staff is to develop a list of testing agencies qual ' Ified to conduct tests of dust envi ronments containing asbestos, determine estimated costs of test programs, and report on methods used. 4. The Chai rman is to include this subject in his report to the membership and request funds from the Board of Di rectors for a standard industry test program. - 13 - 5. Request that the Safety Committee recommend what is needed to protect the applicator working in these conditions. It was reported that contractor organizations had requested guidance from the Association on the problem. The possibility of drafting an ASTM standard on joint treatment compound was discussed but no recommendation was made. An opinion was expressed that asbestos may not be an ingredient in joint compound within the next three years. It was further speculated that contractor groups such as GDCI and iaV/CC may wish to participate financially in the develop ment of an industry safety program for hazardous dust protection. ITEM II - NEW BUSINESS a) Product endorsement. The Technical Committee took a position against the endorsement of any product or tool by any manu facturer outside the Association in any Association literature. Questions relating to this subject rightfully belong to the Board of Directors and legal counsel. COMMITTEE ACTION: A motion was made, seconded and carried to remove this item from the agenda. b) Record Vaults. A request was attached to the agenda from Planning/Design Consultants for data regarding vault construction for record storage. UL has such data and the committee recommended the inquiry be directed to UL for answer. c) Specification for application of finish materials outside of 55 to 70F. A question was brought that ANSI A97.1 should clearly state temperature application limitations for materials such as joint treatment. The committee suggested that 55F minimum should be shown in bold type for such application in future revisions to A97.1. ^ 2 & S2 L__ DE. EX. NC - 15 - and urgency of the metrication problem. We should not ignore the problem now, and then later, when forced to comply with new require ments, be in a disadvantageous position. Old test data will be affected by new measures. The committee recommended that the mem bership participate in industry activities toward metrication. It was further recommended that a task group be appointed to develop recommended metric units for all basic board dimensions and that the recommendations be sent to the Manufacturing and Mining Committee to be utilized in their work on conversion to the metric system. A task group of Messrs. Shull, Lehnert and V/eightman was appointed. ITEM 11-63-73 ASBESTOS IN JOINT COMPOUND The secretary reported that member companies were appointing representatives to serve on a Special Association Committee to eval uate and recommend a pilot test program. The first meeting of the Special Committee had been scheduled for August 8, 1973 in Chicago. ITEM II - NEW BUSINESS a) Texturing of Gypsum Wallboard Ceilings. The need for an Association special 'recommendation on the application of water-based spray texturing to ceilings was reiterated. A draft copy was re viewed and approved for immediate printing. b) Laminating Gypsum Board to Ceilings. Mr. Abbey reported that there were problems in the field occuring whure a second layer of gypsum board had been laminated to ceilings several years ago without the use of fasteners. Some of these ceilings were separating and gypsum man ufacturers were being blamed for the casein type adhesive failures re sulting from improper application procedure. Mr. Abbey maintained that these practices were contrary to recommendations of the Association at that time. c) "ANSI Reporter" Publication. The Association has been dis tributing copies of the publication to the committee for information. The "ANSI Reporter" reports standards actions of ANSI as well as general news items. Comments end problem areas relating to ANSI standards actions should be forwarded through the Association. d) Weights Supported by Walls. Mr. Lehnert reported that questions are frequently received concerning the structural values and recommendations for hanging shelving and brackets and the proper fasteners to use with walIboard. l/vv n .P ' T n m
