Rochdale Insert the following in 1st paragraph and omit sentence on fourth line commencing "The data etc*" A Mortality study of a cohort of asbestos workers was commenced in the 1950's. It has been periodically up-dated by enlarging the cohort as workers qualified for Inclusion, thus constituting a retrospective/prospective study reported on in 19551 19^4 and 1966* The latest report is at present being compiled* In addition a limited morbidity study was undertaken in 1966 and the data* based on the experience of 290 men* was analysed by the British Occupational Hygiene Society's Asbestos Standards Sub-Committee and led to the Soclety*s recommended Standard for Chxysotile Asbestos (published in 1968)* This population has been reviewed and the cohort enlarged at the end of 1972* This data is at present being analysed by the 80H3 Asbestos Sub-Coanittes which hopes to publish its findings soon* Page 2* Pinal taragraoh. 7th line Insert as follows " after 19 years of exposure observed) 1*86 expected* p m 0.04)* In this entire population there were 0 cases of lung cancer observed where 9*20 were expected (p 0*11)* All $ esses etc*" Omit the sentence on line 11 of this paragraph* "The expeoted p 0*11)*" Mesothelioma Please amend as follows (where underlined)* 130 mesotheliomas have been recorded in the Rochdale factory of TEA 1 all but one were first exposed before 1949) /eont'd*** ! o ! ftr*rLCXtf W'rijr'fc'.'***: / / / Ar WP Howard 2- 19th July, 1976 TAG Construction Materials T.td- 1 think you should make it clear that the two cases who also worked for J,V. Roberts are part of a larger number of "asbestosis" claims from that Company, According to my Annual Report to the T & tl Board for 1970 - 1971* based upon information supplied to me by Hr* J,M* Atkinson, J,W Roberts had been responsible for 1 mesothelioma between 1948 and May 1970 Between 1948 and 1970 T & R legal Department recorded $4 cases of asbestosis** related disease, which of coursie includes the case of mesothelioma* In view of the many eases of mesothelioma known to have oceurred in Leeds among ex~J,W, Roberts employees (at least 40), it is obvious that the record-keeping at JV Roberts (and TAG) leaves much to be desired* If you W3nt me to go into this matter in greater detail, let me know and Z will scan the records of deaths of J*V* Roberts employees which Z used to receive before the TAC merger* Zn the same T 4 R Board Report Z indicated that between 1948 and 1970 TAC had been responsible for 21 cases of "Asbestosis", At that time only one mesothelioma was recorded among ten deaths, but in seven cases the cause of death was not known* - TOAL SUMMARY ' Page 10, "We have /escribed cases " Z would be happier if you omitted the final paragraph* The present review by the BOHS Sub-Committee is nearing completion and may well lead to a different standard* Furthermore! it is not valid to use the mortality data to attempt to exonerate the present standard aa this data hat not been (atonaslyeseedtheinfitnhealsadmreafwtaoy fbtyhethe"BBri*g0h*Rto*Sn*PapIert"hwinhkichitZwhoauvlde be helpful to you forwarded today to Mr* R*A* Vella for approval for publication and Z trust that you will ask him for a copy.
