Recommendation: Drop those products from the reporting forms to reduce their bulk and obviate the reporting and collection of useless data. 3. There are reported discrepancies in the list of members * product trade names, by report category. Reconendation: Mr. Barnhart ask each member for an up-to-date list of trade names for publication to all members. 4. Delays of several months in feed-back from Price, Waterhouse during 1969 were reportedly caused by one member's data pro cessing difficulties. That member is having similar trouble now but expects to catch up by the end of April. Recommendation: All members determine if they can report by the end of the following month; if so, revise the instructions for reporting accordingly. 5. A table of industry shipments for the ten years 1960 through 1969 is attached and made a past of this report. Note: After adjusting 1966 for those items unreported in 1969, Industry shipments grew from $88.7 million to $92 million, growth of 3.7Z. REPORT OF TECHNICAL & RESEARCH COMMITTEE J. K. Barnhart reported as follows: Since the November 2, 1969, NXMA Annual Meeting, the technical activities have included the following: AS7M C-1S, PHILADELPHIA, PA.

M. Barnhart repcrttd on the activities cf the Committee In accordance vlch the Minuets o choir meeting, vhich is attached hereto and cade part o these minutes. MTKrRAL FIBER SECTION* 5ZPGJIT In the chairmen's absence, J. M. Barnhart reported as follows: Insulation K-Valuest This project was completed at the March 6, 1970, meeting In New York. The K-Values of glass fiber Insulation were firmly established, and it was based on nine micron fibers. These values plus 102 arc to be used la writing military and federal specifications. Insulation UL Listing for Fire Hazard Classification This project was also completed on March 6, 1970, at the meeting. Underwriters Issued a letter on the subject of classifying in sulation by category instead of the usual ratings for flame spread, fuel contribution and smoke. The first insulation class ification will be FEC 25/50. This was well received by all % concerned, and to date two members are presently using this system. This will give more freedom in our testing, as we will not be required to do the number of tests required for classifi cation, and, likewise, the labelling of our product will be ouch simpler. Temperature Limits The Temperature Limits Tests were conducted by Gustin Bacon and PPG and the conclusions reached from these tests indicate that when the binder is completely removed from the insulation In contact with the hot surface and the product vibrated in accor dance with the tests described In U.S. Coast Guard 32MA3C the thickness of Insulation is reduced due to the felting action of the vibration. However, some of the members felt the vibration cycle was too severe and mors research should be done as to what vibration cyele should be established. Also, a warning should be Incorporated in each company's literature similar to that shown in Johns Kanville Flame Safe Glass Fiber Pipe Insulation brochure. Military Specifications The coQB&ittee members will attempt to eomblne Military Specifications MIL-I-2818, MIL-I-15475, MIL-I-16411, KIL-I-22344, MIL-I-22023, MIL-I-23128 also the cotm&ittee Federal Specification HHI-558, HHX545 and M2L-X-742. 6 - Thermal Conductivity Test This project has been on the books for some tine. An initial study was made by the participating laboratories and correlation was reached on a 9 lb. per cu. ft. glass fiber up to 150 F. mean temperature; however, no correlation was reached on other samples at higher mean temperature. The program was started again with renewed effort. Each company exchanged Information on their equip** aent to determine what could be done to standardize the unit and the second phase of the program was to prepare a high temperature standard for calibration and a Round Robin study. Two members were scheduled to prepare these samples, however, this work was never completed. It was agreed that this program be tabled. REPORT OF Tag DUCT COMMITTEE J. M. Barnhart reported on the activities of the Committee in accor dance with the Minutes of the Meeting which is attached hereto and made part of these Minutes. REPORT OF THE OCCUPATIONAL HEALTH & SAFETY COMMITTEE In the chairman's absence, J. M. Barnhart reported as follows: A joint cocssiteee meeting was held on Wednesday and Thursday, March 25, and 26, in the Fiberglas Tower in Toledo. Represen tatives of Johns-Manville, PPG, Certain-Teed/St. Cobain and 0C? were present, as well as Mr. Jack Barnhart of NIMA. The items discussed were the fibrous glass studies being carried out by Dr. Clark Cooper of the University of California, the duct study being carried out by Professor Cholak of Kettering, and the status of the necropsy study being carried out by Dr. Paul Gross of the Industrial Hygiene Foundation. Each of these studies will be detailed below. FIBROUS PARTICLES IN AMBIENT AIR - Cooper The revised protocol of this study, which was received on March 12, wrfs reviewed and approved. This study is underway and is expected to be completed by Mid-year. 7* OCCUPATIONAL & OTHER ENVIRONMENTAL EXPOSURES TO FIBROUS GLASS VENTILATION SYSTEMS - Cooper The completed report of this study was reviewed In deteil end the results were found to be favorable. It is felt that the report should be coopletely edited, and some areas rewritten by Dr. Cooper in order to emphasise important points and reduce the document's length. We will be meeting with Dr. Cooper on Thursday, April 16, to discuss the matter. THE ASBESTOS WORKERS STUDY - Cooper The study was only briefly discussed. We have not received the final report. It is expected ve will receive the report about the first of April. This study will be discussed with Dr. Cooper at the April 16 meeting. It is hoped that it can be finalized at that time. SHEET METAL WORKERS STUDY - Cooper The proposed protocol was discussed only briefly since it is anticipated that this study should complement the asbestos workers exposure study. The protocol is also expected to be final ized in Chicago with Dr. Cooper. It is anticipated that this study will begin after the completion of the Ambient Air Study and should be completed by late Fall, 1970. NECROPSY STUDY - Gross It was brought out during the meeting that the four fibrous glass manufacturers have now funded the seudy. Dr. Gross has received all of the necessary necropsy material and the study is progressing smoothly. KETTERING STUDY - Cholak A draft copy of the completed Kettering Duct Study was reviewed end accepted as written with only minor changes. The suggested bibliographic reference will be added to the report. This reference will be forwarded eo Professor Cholak by Mr. Barnhart. It was brought out during ths meeting that, as a result of the studies, Kettering and at the University of California, objective documented data is now available which lends perspective regarding airborne concentrations of fibrous glass in air handling systems containing fibrous glass and work exposures to men installing fibrous glass materials. If called upon, Dr. Cooper cen give objective and effective reporting on his findings and conclusions regarding the fibrous glass exposures and health. -8- REPORT OF TOE EDUCATION & LEGISLATION COMMITTEE Chairman C. Sheckler reported as follows; Legislation to eliminate the use of fibrous glass ducts, and duct liner In air transmission systems has been extremely active during 1970 to date. Some of the major legislative activities are as follows: KANSAS BILL 8-1642 - HEARING 2/12-16/70 This Bill was introduced by James L. Francisco. Representative Francisco cold our NXMA representative chat the Bill was intro duced at the request of Dr. Irving Sellkoff through the Wichita International Association of Heat and Frost Insulators and Aabestos Workers. Proponents for the Bill were Dr. Irving Sellkoff, Mt Sinai Hospital, and two representatives of the Heat, Frost and Asbestos Workers. One Asbestos Worker was R. Tucker, and the other un-naoed. The Asbestos Workers testimony was brief end very general in conjunction with costs, air pollution, clean interior air, and the contamination caused by fibrous materials installed next to the air stream. Dr. Sellkoff testified for approximately one hour. He reviewed his routine statistics on the health studies of the insulators. He dlscuseed asbestos at length end then by inference attempted to relate the seme health hazards to fibrous glass as to asbestos. There were over twenty people appeared in opposition to the Bill. Most of these people appeared by arrangement of our NIKA Committee. The Sheet Metal Workers, Sheet Metal Contractors, Engineers, Archi tects, end our Committee members testified. Dr. Paul Gross, Di rector of Research, Indue trial Hygiene Foundation of America, testified as our NIMA medical expert. The Kansas Legislative Committee wss comprised of 19 members. There wee a 16 to 3 voce in opposition to the Bill. A Rouse Con current Resolution No. 1106 was then introduced to place the Bill in e study committee for report end recommendations to be submitted in the 1971 legislature. We Immediately vent to work on the Resolution and was advised on 3/9/70 that the Resolution was defeated end no interim study will be held. Unless reintroduced, the Bill in Kansas is dead for the current year. -9- MASSACHUSETTS BILL H-1074 - HEARING 3/2/70 This Bill was introduced by David C. Ah earn. We have been unable to determine at who's request Representative Ahearn Introduced the Bill. We were advised chat the Massachusetts local of the Heat, Frost and Asbestos Workers were not aware that the Bill would be Introduced again in 1970 inasmuch as a similar Bill introduced by Ahearn at the request of the Asbestos Workers was defeated in 1909. The Inference was that someone from the Asbestos Workers in Wash ington had requested Aheam to sponsor the 1970 legislation but had not conferred with the Massachusetts local. Mo one appeared or communicated as proponents of the Bill. Six people were present in opposition to the Bill. We did consider able background work with the Chairman of the House Legislative Commit tee through legislative counsel. When no one appeared in favor of the Bill, the House Chairman asked us to summarize our testimony. C. L. Sheckler summarized for the NIMA Committee. J. Connelly, International Vice-President for the Sheet Metal Workers and a representative for the Sheet Metal Contractors briefly voiced their opposition to the Bill. We had been advised that Dr. Irving Selikoff would definitely testify in Massachusetts as a proponent of the Bill. We, therefore, had Dr. R.T.P. deTreville, President of the Industrial Hygiene Founda tion of America, present to testify as our medical expert. Written statements and supporting publications were submitted in lieu of testimony. The Committee Chairman has advised us that the Bill is dead for 1970. CALIFORNIA BILL A-384 This BUI was introduced by L. Townsend. Assemblyman Townsend is from the Torrance District - Los Angeles area. Our NIMA Committee recognized that the California Bill was of the utmost importance to A. Hutchinson, President of the Heat, Frost and Asbestos Workers. This was obvious by Mr. Hutchinson's edi torial, Dr. Selikoff*s Insulation Industry Research Fund Report, and the physical layout of both in the February 1970 issue of the Asbestos Workers publication. -10- CALIFOSMIA BILL A-384 (Cont'd) We also recognized Chat if this Bill went to a public hearing in the California Legislature, we would be faced with our most diffi cult defense to-date. We, therefore, worked with the West Coast Asbestos Workers, Sheet Metal Workers, and Assemblyman Townsend, Sponsor of the Bill. In addition, we also worked closely with the California Manufactures Association. Our objective was to prevent the Bill from cosing to a public hearing. Assemblyman Townsend requested the Bill to be "taken off calendar". He indicated this was a permanent measure which would effectively kill the Bill. He claims the Asbestos Workers took advantage of him by having him introduce legislation which involves a Juris dictional matter. Assemblyman Townsend took the Bill off calendar, however, an Assemblyman H. Johnson, has revived it. Johnson claims that his purpose is to amend it by removing reference to fibrous glass and using it for another purpose. This has not been done to-date and ve are currently working on the matter. Our NIKA Committee is fully prepared for a public hearing. We have our people and presentations ready. Our medical expert is on call. The Sheet Metal Workers, Sheet Metal Contractors and a number of other construction organization representatives are also standing by. KENTUCKY BILL H-743 This Bill was introduced by Thomas Ray. We were advised of this legislation on March 17th. We have no background regarding who requested the legislation to be sponsored. Through our contacts In Washington, we reached the Recording Secretary of the Sheet Metal Workers in Kentucky. Be, in turn, contacted Representative Norbert Bloom, Speaker of the House. The Recording Secretary has assured us that Mr. Bloom will with draw the Bill and it should be considered deed. The Kentucky legislative session ended March 31st, therefore, any Bills not brought out of Committee by that date, automatically die. -11 NEW YORK CITY ENVIRONMENTAL PROTECTION ADMINISTRATION REGULATIONS NO HEARING SCHEDULED Dr. Jacob Friedlander, Executive Assistant of the Environmental Control Board, New York City Environmental Protection Administration, has ad vised us that there is a regulation being considered that will eliminate "asbestos and all ocher fibrous materials" that can become Airborne from air transmission ducts. We questioned the background and reason for this regulation. He would not reveal the source of the recommendation but indicated that Dr. George James, Dean of Mt. Sinai is a member of the Control Board. A meeting was held with the Commissioners of the Environmental Protection Administration, Department of Air Resources, and Department of Water Resources. C. L. Sheckler reviewed the fibrous glass medical-scientific research studies and results, plus other background information. As a result of this meeting, the EFA agreed to remove the section of their proposed regulations regarding fibrous glass in air transmission systems. The interim regulations have been promulgated with no reference to fibrous glass. We are following up this matter regarding a Public Hearing prior to promul gation of permanent codes, rules and regulations by the EPA - New York City. In addition to the foregoing legislation, there has been extensive corres pondence and communications with contractors, school boards, hospital boards, engineers and architects; plus housewives and customers in re lation to health hazards of fiber glass. The fear of fibrous glass as a health hazard among the general public appears to be more serious than asbestos, and gaining momentum. This is the situation in spite of the documented evidence that fibrous glass insulation is an inert material with an ACGTH threshold limit value of nuisance dust. The material being published by Mr. Hutchinson, and the potential dangers being publicized by Dr. Sellkoff, is having an adverse effect in the en tire fibrous glass industry, including home insulation, textiles, as well as duct board, liner, and celling tile. -12- ASTM - C-16 PROPOSED COMMITTEE ON POTENTIAL HAZARDS ASSOCIATED WITH THERMAL INSULATIONS Subject Committee Meeting was held 12/22/69. The scope of the proposed Committee vas to survey the field of insulation in regard to potential hazards in manufacturing, installing, testing, handling and use of all materials covered by C-16. C. L. Sheckler, W. Gubar and J. Barnhart attended, representing the Interest of the NIMA Education and Legislation Committee. Extensive medical-research studies, litigation, and other complexities Involved in substantiating toxicological data was discussed, and it was determined that in view of the work underway, the ASTM C-16 would take no further action except to keep informed. FIBROUS GLASS POSITION PAPERS Fibrous Glass Position Papers have been prepared by this Committee. They are entitled "Health Aspects of Fibrous Glass in Heating or Air-conditioning Ducts"; "Questions and Ansv/ers about Fibrous Glass in Heating and Air Conditioning Ducts"; and "Summary of Documented Medical Evidence on the Health Aspects of Fibrous Glass". In addition, a back-up file of complete information and publications on the subject of fibrous glass has been com piled. This information has been and will be used to take a positive approach concerning questions and problems related to health and taxicology. PUBLICATIONS AND PRESENTATIONS This Committee is currently preparing a paper for publication concerning health aspects of fibrous glass. A presentation will be made at the MICA General Meeting by J. Barnhart and C. L. Sheckler on the subject of NICA-NH1A relationship for oc cupational health and safety. Both of the foregoing communication projects will be of a positive nature to emphasize Insulation Manufacturers activities in the area of health and .safety. GENERAL The Education and Legislation Committee has been working closely with the Health Committee on medical-scientific research projects sponsored by, or of, Interest to NINA.
