Hastings Bath Iron Corp. Bath Maine Dear Mr. Hastings ; On May 31 1966 you inquired about a band saw used by the pipe- covers at this shipyard The unit is made up of a dust collector and a saw which has a built plenum at the base of the machine A sheet metal duct for attaching a suction the upper blade guides follows was added by this yard to the upper wheel guard hose to remove dust from the work area just above The specifications for these two units are as in } la Band saw light duty with 20 dia wheels and a ; sliding table 44 x 54 with graduations for making elbow segments . - b Electrical characteristics 1.5 H.P. 220/44 3 phase 60 cycle A.C.motor for C.

Environmental Survey of Pine Covering Operations At The Cath Iron Works 1, Introduction ny This survey was requested by Dr. B. G. Ferritso complement > mecical survey of a work population exposed to asbestos during pipe covering operations at the Bath Iron Works A previous study of these operations had been carried out in the 1940's and reported by et al Fleischer This report covers the value of additional the results of the present survey suggests environmental study and presents broad recommendations for dust control on asbestos handling operations II Ocerations A. Materials There has been little change in the material used in pipe covering operations since the previous survey The common insulating felts are still based on amosite and chrysotile asbestos Asbestos molded pipe covering is now commonly used The most significant change in materials has been the greater use of fiberglas and the introduction of form glass insulation Neither of these latter materials are felt to constitute a health hazard and therefore have been given little attention during this survey " A list of the materials now in use at this shipyard and a brief description of their composition is given in Table I. Process - rely ABl.though ' there has been little change in methods during the past twenty years it is felt worthwhile to indicate the major work areas ; ae and those changes that have been made PRODUCED ne Ss 514114 2 prohibited vacuum cleaner station should be provided for this purpose .
