I :tm concerned that asbestos con tinner, to be used extensively by the Navy in the fabrication, inctnllnliwn, repair and renewal of pipe and boiler Insulation. Many years of r.edicul research have firmly established the serious effects of iniutlcd asbestos fibers reaching the lungs and resulting in lung cancer and asbortosic. Although alternate materials have ^ccn available for years, NAVSHIFS has not taken action to prohibit ^uso of high asbestos content materials in insulation. 2. Reference (a) reported to HAYSFT- the results of a study conducted by the Na^al Ship Engineering Center, Philadelphia Division to determine actions necessary to ni;umise the health hazards to which insulation workers ar.j exposed while working with asbestos. This study included inquiries to all Naval s,.nJ private shipyards and visits.to representative Naval and privutc slipyarus on the East and West Coasts.- In addition, some 20 manufacturers and vendors of thermal insulation wore contacted. This report concluded (l) considerable usbestos-containin- insulation material currently is being used in Naval applications and stringent handling precautions are not being enforced in all instances, and (2), the use of high-nsbezl-os containing thermal insulating materials should be curtailed duv to hazards to the health of insulation workers. FUMED stated in reference (b) t:.at "the high asbestos content materials should be replaced uiiere feasible from an engineering point of view by materials of lower asbestos content." Reference (c), which is a'proposed MAVSKIfo Instruction.for control of asbestos hasardy, requires safety controls to bo taken by s'ulpyardr. nnd merely provides a list of replacement matcritiln for high asbestos content insulating materials. 3t An example of concern by other countries with this problem is a recent article Jn the Journal of Naval Engineering (cony attached) "The Elirdra tion nr Arbrst-i;: in !*.

I recommend the following additional actions be tuken promptly to b. Require licit high asbestos content materials removed during nuc~ powered chip overhauls be replaced with other materials. Howoverj it m: be desirable to re-install pre-formed asbestos materials in cases where no insulation ro-vork is required since minimal Jiazard results from r.ucl re-installation, i [C. Initiate action to eliminate high osbcst03 content insulation froruall new construction ships and to discontinue use of high asbestos content insulation in ships in.overhaulj where practicable, I would appreciate being advised of action taken. ) 4 ( 00103".
