Roberts Ltd., Midland Works, Armley, Leeds, 12. AttentionI- Mr. N.L. Dolbev Dear Sir, I was referred to you by Mr. H.A.Williamson of the Atlas Asbestos Company Ltd.. Montreal Branch, for further information about your "Sprayed Limpet Asbestos" process. c We actually are interested very much in the use of asbestos `under any working conditions, specially regarding the danger of asbestosis. What made me contact your Canadian subsidiary is the fact that the question arises whether the workers employed in the appllcatioi of insulation by the process mentioned above might not be exposed in such a vaj as to develop such a disease. I understand that in England you have been using this process for quite a number of years, whereas in Canada it has been in use since 1935 only. V.......... . ... . ' .1*1 In your experience in England,' did you ever have to pay compensation for asbestosis occurring through the exposure to the dust, produced when applying the asbestos insulation by the above mentioned process. If so, we would-be very grateful if you would let us know about the details of such cases that may have occurred. c% It is understood that this information will be kept as highly confidential, and that it is not to the detriment of the company, but rather in view of helping in the improvement of the process to reduce the dust if possible in case there is a potential danger for the health of the workers. . : .... `. . ./*. - . r<........ .. .
