You will recall from previous efforts of this nature that the AIA, with approval of its Governing Council, has collected information on dust levels in factories and mines and mills from companies belonging to national associations that are members of the Asbestos International Association. Surveys were conducted for 1983 through 1987. This survey applies to 1988. It is understood that the asbestos producers in Canada will be submitting their information as coordinated by The Asbestos Institute. AIA/NA members and interested firms that participated in the 1987 survey included the following companies for which sincere appreciation is extended: CAPCO Pipe Company Allied/Bendix CertainTeed Hollingsworth & Vose KCAC Henry Company Grundy Industries Monsey Products Nuturn Supradur Vermont Asbestos Group Accordingly, AIA/NA members (less Canadian producers) are requested to give close attention to the enclosures at your earliest convenience. Return of the DUST MEASUREMENT RECORED - WORKPLACE (DMR 1) to this office by March 20, 1989 would allow for collation of the information and transmission to the AIA within the timeframe requested. Presentation of this data on a world-wide basis is planned during the AIA Biennial Conference scheduled for May 1989 in Brussels, Belgium. Thank you in advance for your assistance on this project. B.

This figure should be less than the total workplace figure but may well be greater than the figure for the number of workers under survey (see 8.2) 6 - Method in use Only menbrane filter results should be reported. Please state the method used if different to the standard STM 1; even small deviations from RTM 1 should be reported. If more than one method is used please specify. 7 - Range of sampling time By reporting the range and typical sampling times used one can ascertain whether the determined values of dust con centrations between different countries and/or measuring cen tres are ccnparable, since the sampling -times determine the detection limit. 8 - Data 8.1 - Number of monitored sanplinq locations Ih 'b^brting-ttte duist'- danc^hm(-L\^, tbB y^ultg of personal and static sampling (calculated as time weighted averages on an 8 hours basis) should be reported separately - For each monitored sampling location the annual, mean value has to be entered if more than one measurement took place in this location over the year. These mean values indicate to which concentration columns the respective monitored sampling locations have to be allocated. The number of monitoring sampling locations in the respective concentration ranges must then be entered into these columns. 8.2. Number of workers under survey Report the number of workers under survey in each dust concentration category (number should include workers of all shifts). The numbers needed here are those directly working in the monitored sanpling locations. 8.3 Natter of samples taken over the year Here the total number of samples (personal/static) taken over the year have to be entered.

Whilst appreciating that the DMR returns for 1987 were just being received the Governing Council at its meeting on 9th December 1988 nevertheless felt that as all caipanies would already have their Dust Measurement figures available for 1988 there should be few problems conpleting DMRs for the year. Bus would then enable the analysis and ccnparision to be made for the years 1983 to 1988 (inclusive) in Mr Bouige's forthcoming presentation on AIA Dust Records. This is bhe'Adf';the' aabcaftant'papers toibe*ieSantad m the..qpe*iing, day of the AlA's 7th Biennial Conference in Brussels in May 19819 and your cooperation once again will be greatly appreciated. Would you kindly said' copies of form- CMRl' for 1988 to ycUr Members asking them to record the information in such a way that data from factories in the same branch are on one form. In turn, could you collate the information received from different firms by brand! (without any indentities being divulged) and return the form to AIA by 31st March 1989 so that the total results can then be drawn up. Forms EMR2 for 1988 should be conpleted by National Associations. cc Executive Ccrmittee (without enclosures) Dust Advisory Panel CTD026137 1 NOTES FCR GOIDMCE CN CCMPLETUG TEE DUST WRSDRMNT RECORD FCR TEE VCFKPLPCE (OR 1) These notes are a guide to the cocpletion of the AIA Dust Measurement Record submitted to each Member Association. It is required that each country should nominate a co-ordinator who will be responsible for the return of the completed fonts to AIA. The source of information may vary from company to company since sane will have a central dust counting service and others will carry out such work independently at each individual factory. The final aim is is to have one Dust Measurement Record for each product group branch in a country. 1 - Country Association This is self evident. If an Association covers more than one country, there should be a separate return for each country. 2 - Name and address of co-ordinator It is necessary to supply the name and address of a technically qualified co-ordinator who can be contacted to answer any queries about the filled-in forms. 3 - Product Group * T'- 'if `fheretis!.inore than aae.pbQduct rfjrqjjp. qn.th?, same.; . factory site, separate forms should be completed fob each ` product branch. Please, circle the appropiate product group. 4 - timber of Mines/Mills/Factories The number of individual production units is to be _ recorded. 5.a) Total Workforce This figure should include all personnel on the pay roll at the time of completing the record - office, medical, service, etc. The figures recorded in Section 8 (table) should be restricted to the number of workers who are included in the monitoring survey. .../ CTD026138
