BATXOIUL ACABBB OP SCHSCES ASBESTOS OOSFESB8CE JUKE 1976 The Generic Policy on the Regulation of Carcinogens ie involving the full time efforts of OSHA and the Office of Toxic Substanoes. T.o action ie expected on asbestos until resolution of the procedure in 1979. Pressure is now building by researchers, the V.A.V., and the Government .. to lover the 2 fiber/oc standard. High probability exiete of a 1 fiber/oc . standard. However, the new British approach consists of asbestos concentrations being reduced to the lowest attainable level under the 2 fiber/oc tux, ceiling, further regulation will encourage the use of substitutes. The poseibillty remains for a more stringent standard of .5 fiber/oc or lower. Thie would virtually eliminate asbestos usage. In the interim, the iesue ie attaining oontimicc vorIawJ.de involvement and ooncern as evidenced from the publicity Jt received from the Meet tne PresB telecast Sunday June 29, 19?B and the large international represents tion at the conference. Highlights of Presentations Canadian (McGill Study) * Withdrawl from exposure does not halt the progress of the carcinogenic condition. ( . The longer end/or greater the exposure, the greater the number of deaths. * Smpying influences the incidence of larnyx cancer under conditions of asbestos exposure. * Carcinogenic conditions are moBt prevalent 20-30 years from first exposure. * Eaob year cancer deaths ere on the uprise from equal sample elves of exposed populations. German . One fiber will not produoe tumors. * Asbestos fiber could ect as an aosorber of c^rtTnugen*. Knowledge ie lacking on the initiation of cancer. , r_ * The current U.S. standard allows for adequate control. ' Conditions have changed from the past and the issue ebould be updated in that perspective. c Asbestos vss discussed by Mt. Sinai, J-M, and the U.A.V.
