We have no part-time insulators. C. The most prevalent types of insulating materials used at Repauno in the order of consumption are Calcium Silicate, Limpet Asbestos Spray and Mineral Wool Block. D. We use Limpet Asbestos Spray at Repauno. E. (a) Asbestosis - 0. (b) Lung cancer - 0. F. At Repauno the preventive procedures against air bourne dust are as follows: (a) Our power equipment is installed in an air tight room with an external exhaust system. (b) The tables on the power equipment has installed a vacuum system for picking up heavy particles. (c) All persons working in the room on mechanical sawing of insulating materials are required to wear a dust mask. (d) All persons removing old insulation wear dust masks. (e> All persons spraying insulating materials wear dust masks. GAR:jel ____ __ . --------------- ------------------------------------ DUP 1121881 DU 056299 CC: J. K. Locthcr, Asst. Manager H. D.

A. 3'Alonzo, M.S i= bootos To sxTpplor.pnt that letter and to elaborate farther on each, question in your questionnaire, I subnit the following: 3. Occasionally nschsnies froa other crafts are used as part-tine inrulstors. Ihase ren on vary froa day to day but practically all nschunica gat scua exposure to c-sbu.ttce during field wor.c. 'iZi-sTM is constant handling, cutting, installation, rsaoval and replacanent going on to varying dssracs by sany esployees who are not classified as pipteovarers. C. It la difficult to determine, with any degree of accuracy, the :.ost_ prevalent type asbastcs-cciitaiaiag insulation naterial used. Great quantities of aubastco-centainiag naterials are used on Chvahers "erhs. These naterials cone in any stsber of sizes, shapes, rolls, druns, nixtures with other nccasbeatss-containing naterials, wat, dry, pewdared, paper, siding, floor covering, cloth, etc. Thus to arress quantity is difficult when one tries to ccspsrc. the typo used for the Insulation, its thichr.es s, handling, locale, and naans of application are all factors in the assessing, Jlore than one supplier is used to obtain cur naterials and ths type naterial used varies with the Chanters Yorhs Construction group and ths Chanbsrs Yarns Engineering KSC group. Eased os quantities purchased for use by ths latter group during 1365 as ccspared with 1966, there is a distinct over-all decrease in use in 1J66 of asbestos-containing naterials. 5. With e total of 1,420 wage roll sen in Class H, UZ or 17, ICO are so classified for puLncnaxy reasons. Of this ICO, two are plpecsverers. (See letter of 0/13/60.) Since the year 1330 through 1966 to date, ve list 1,313 esployees as deceased. Of the3e, 130 died froa pulnor.ary reasons and of this 130, 53 ware froa carcincaa of ths lung. Of ths total deaths, only 5 tare ever plpecsverers. One of these insulators died listed as "cor pul ocaala"--the resaining 4 were ncnpulaonary causes. V. laid, Jr., Jt.3.
