FILE NAME Quebec Asbestos Mining Association QAMA DATE 1980 Nov DOC QAMA163 DOCUMENT DESCRIPTION QAMA Bulletin Vol 4 No. 5 Proposed regulatory action unjustified In a brief submitted to the Ontario Ministry Labour the Association des mines d'amiante du Qu^'beccontends that there is neither a scientific basis nor any medical social or economic justification for a regulation proposed by the Ministry that would lower the permissible average exposure to asbestos in the work environment Basing itself on the 1978 Occupational Health and Safety Act the Ministry is proposing that the permissible level of airborne dust emissions in the asbestos mining and manufacturing industry be reduced to one fibre per cubic centimeter Unwarranted haste The Association is unable to find any justification for the suggested stan- dard which seems to have been largely precipitated by recent media coverage that has been more sensationalist than informative Moreover the proposal comes at time when a Royal Commis- sion of inquiry into all aspects of the asbestos health issue has barely begun its work in Toronto This contradiction is underlined in the brief which has been documented from a scientific and medical as well as technological economic and social point of view Pointless reduction medical research studies including the results of the latest and most important epidemiological study on the effects of asbestos exposure The AMAQ brief points out that at an exposure level of roughly 20 fibres per CC a level which has not been found for many years an increase in risk is practically undetectable At 2 fibres per cc - the current standard - it is scientifically impossible to prove any increased risk Tightening the standard any further would thus be utterly pointless and would provide no addi- tional guarantees with respect to workers health In view of the fact that the present standard should be considered safe as acknowledged by both the Canadian and Qu^'bec governments and since a reduction of the norm to 1 fibre per cc would not increase safety the only effect likely to arise from enforc- ing such a needlessly severe standard would be to hamper the asbestos industry's ability to function effectively Technologically unfeasible The AMAQ brief also establishes that existing technology does not per- mit a constant average exposure level of 1 fibre per cc to be maintained in the mining sector The Association supports its poi- tion with numerous scientific and Based on the results of dust monitor- ing and control measures and statisti- cal data compiled by the Association and its member companies the brief shows that even with the utmost effort and using all means available including the very latest technology it proved impossible even the cleanest and most modern mine facilities operating under optimum conditions to reduce average airborne dust concentrations below the level which is now obtainable on a continuous basis and which varies between 1.5 and 2 fibres per cc Planned standard unjust However the fact that it is neither feasible nor possible at present to reduce the norm should not be a cause for concern As the report emphasizes it has been medically proven that aside from those exposed to the higher dust levels of more than twenty years ago the health of asbestos workers is comparable to that of the general population It is hoped that the Association's brief which also puts in perspective the importance of the asbestos industry's economic contribution to Canada will convince Ontario Ministry of Labour authorities that the proposed standard is indeed unfair since it is scientifically and medically unjustified technologically unfeasible and potentially very damaging in economic terms L | Bulletin Information centreand three research projects funded by IRDA When the Institut de Recherche et de D^'veloppement de l'Amiante IRDA was founded it was decided that not all research work or projects would necessarily be done within the IRDA Itself in order to take advantage of all available resources that could help the Institute to fulfill its objectives Within the framework aof Research Support Program it was anticipated that certain projects would be entrusted to the groups best able to produce good results such as public perapublic or private research centres or organizations in the academic or industrial sectors In keeping with this policy IRDA's Board of Directors has recently acled on the recommendations of the Scien- tific Committee to authorize 224 476 in grants aimed at financing an asbestos documentation centre and At the Universit^'de Sherbrooke's asbestos documentation centre electronics facilitate reference work three research projects and G Poirier Ph D. from the Univer- invaluable information on the biologi- cal effects of various materials proposed as asbestos substitutes This project is a follow on recent studies which reveal that when pure chrysotite fibres are incorporated in mixtures chemical changes occur in the fibres that can modify their biological effects Applied research In accordance with another IRDA objective to improve existing products and develop new asbestos applications a 52 650 grant was awarded to R.
