Welch Marshfield As outlined in oirr initial discussion on March 22 and ' covered in some detail in our cloning discussions on Haroh 28, the ` objectives of my visit to Marshfield at this time were to-. 1} conduct a quarterly audit of the asbestos situation in both the Mineral Core Plant and the Core ill, 2) hold employee educational e e s ^ n f simiiar to those given during the week of February 26 - March 2, I73,.!*. 3) wiUl Moria Pacourok's assistance, collect com>arative breathing zone samples of asbestos dust by simultaneously sailing Our method and the Department Df Labor's reconmended9 f0i1Ovrl"9 report covers the various aspects and ' cations of each of these objectives in the order in which they are listed above. QUARTERLY AUDIT: Mineral Core Plant ' A. Installation of the new sander immediately down the process stream from the old aandor, which enables a single sanding pass to be made on cores out of the dryer, has some definite advantages for control of employee dust exposures and, -- coincidentally, minimisation of overhead in this area. '----\ Because each mineral core block arriving at the scissor lift asbeato*1 d fb? EOftlfl9 31)4 fading area is now fully sized, asbestos duat levels entering the workroom air from the sequential stacking (and dropping) of cores onto the Scissor f"1 to? expected to be drastically reduced from levels . found by the QSHA Compliance Officer on January 9. The fbabof `s samples were taken during the first pans (unsized] of the mineral core blocks through the Sander ^ ^ unilaterally-sanded mineral core block n W i U fWrthftt reduce employee exposures to asbestos 2?re block rotation and the additional handling unneces^aryr h SeC<SU<i pass; thW>ug the sander are now AURdufoj WY02-000587 AB001568 : While accomplishing an obvious impnoveraenjfc in control pf ' - asbestos around the trip Saw-sruider arfea with the addition Of- . the new Sander, a coincidental induction in overhead could also be realized. With the decxeaee in handling brought - aboyt by the addition of the new sunder, two employees could perform the work tasks formerly requiring four employees. . Two employees could unload and stack mineral core from the dryer,' feed the trim saw/sandsre and sort and grade the aimed, ' k ; , -i sanded mineral core blocks. Because less handling is necessary; some reduction in the percentage of broken cores in this area is also likely. - . . `The planned modification of the trim saw area from Bavs to rotating ^hogging- heads, 43 indicated by Jim Gallatin, should bring about another improvement in asbestos control by increasing tho effectiveness of dust pickup at these positions. evidenced by the substantial dust accumulation immediately inside the access door on the new Bander, further improvements in design of the internal dust pickup heads could be made. The relative importance of such a modification becomes apparent a*ter isolating and studying significant sources of mineral core scrap and duet which Ultimately lead to the accumulations of these materials in evidence under and alongside the process iinc in this ft-rea. . . v . ^testos levels at the sorting and g rading < stations, as indicated by the February sampling tests on employees working in this area (Steve Cant's April 4 report on Harm s February tests is attached for your information) , have finally dropped below the 1976 OSSA asbestos standard 1imTFi" tor two months in succession: These excellent results are-- reflective of several fine points In asbestos control in this woric ^reai 1 ) a mote consistent phenolic glue size application o the cores out of the dander, 2 ) sizing cores on the first Pass through the Sanders (thereby minimizing the 'puffing' of m o r a l core dust during stacking of unsized cores oq the . receiving scissor lift) , 3) better handling practices and 4) more frequent and thorough cleanup activities. An active ongoing control program ifl urged with respect to those contributory factors responsible tor t h e s e fem.it. U U s aiga exposure levels can be continuously maintain*?

Asbestos seen to be n .r H ,, ? work room air from this work sLatiOn was p icularly intense on Saturday morning, March 23. WY02-00059D AB0O1571 -5- Investigation o a probable cause fox the more pronounced problem of arch 23 revealed a coincidental situation involving partially-sized mineral core from last summer's inventory and i some side stile adhesion requiring pry separation. Engineering is presently studying a hood system design for this position which would capture the dust released near the point of generation. Another suggestion was made to locate a slot hood on the outlet end of the electronics to remove Surface dust and minimize potential release to the in-plant atmosphere at the abrasive planer feeder's position. D. A white film of dust on the face of the back Gander juxtaposed with the abrasive planer feeder position provided ample evidence of periodic system malfunctions. To significantly lessen the magnitude and extent of work room air contamination with asbestc fibers during infrequent system plug-ups or baghouse overloads, it is recogmetided that a pressure-sensitive warning system be installed near the baghouse which would trigger buzier/flashlng light alarms situated at the feeder positinns on the abrasive planer and double-end tenoners upon any sudden change in the negative air pressure sy,st<Ha~ Such a warning nyntom yniil d hahl machine operators to take exigent steps to stop thair machines and the product "feed" ahead of the time visible dust begins to spew out of their machines. Another desirable aspect of this system is that it will reduce markedly the asbestos exposures of those unprotected employees who work in areas contiguous to mineral core work areas. c. fugitive dust clouds continue to escape from the inlet end of the main abrasive planer, especially imirediately following entry of the tailing edge of a railed mineral core block into the abrasive planer. It appears that a marked drop in the efficacy of the sander negative air pickup system occurs at thi$ time, resulting in the loss of mineral core dust to the work room air. b- Removal of the negative air pickup system fane from the inside work room environment or enclosure of these fans is needed as evidenced by the sifting of dU3t buildup from around these tans down onto the floor or loads of rails stored immediately below the fans (S-- 1) . So long as the fans occupy thair' prepend positrons in the Core Mill, they will continue to act as sources of asbestos contamination for this work place, e . At the abrasive planer feeder position, another problem of significance which undoubtedly contributes to the high asbestos exposure in this employee's breathing zone is the makeup air system. One Of the inlets of this system Impinges directly down upon the railed mineral core blocks at the feeder position, blowing surface dust up into his face. A repositioning of this particular inlet is recommended. n M O ."i WY02-000591 AB001572 -6- F. During my discussions with Mr. Milan Racic, OSDA Compliance Officer/lndustrial Hygienist, on March 18 and 19 in Milwaukee, it became apparent that OSHA has extended the depth of the asbestos standard, section 1910.93a, with the inclusion of the teachings contained in the HIOSH criteria document. This extension has touched on all areas listed in the OSSA asbestos standard and served to expand each of them considerably. According to their new definition -- each employee "exposed to asbestos fibers" shall be covered by all applicable sections of thfe asbestos standard. To eliminate the probability of individual interpretation, "exposed to asbestos fibers" has new been defined as exposure to levels egual to or greater than 1 fiber/cc greater than 5 microns in length on a tineweighted average or 5 fibers/ce greater than 5 microns in length for a ceiling limit. Because of this interpretation, it is recommended that my previous reccroaeadation ind-ieating no showers would be necessary in the Core Hill Ibaaed upon our monitoring program which indicates near compliance with the 1976 OSHA asbestos standard) be disregarded and be superseded by a reconmendation to install aucb facilities and make these available to the employees (wearing uniforms) in a manner "" coinslatent with the program in effect in the Mineral core Plant. G. 9in.ee asbestos fibers were found in the dust accumulations on lunch tables ib the Cora Mill lunch room, each table should be wiped clean (with a damp Cloth) at least Once a day.. The floor in the lunch room should also be attended t-n <n a similar manner to minimire asbestos fiber contamination of lunch room air, etc. II. At least for the present, all employees working either in the north aisle (alongside the double-end tenoners) or against the north wall in the Core Mill mineral core area should wear masks just as operators and offbearers oti the double-end tenoners now do. The justification for this recommendation is three-fold: 1) Some consideration is being given to modifying, hopefully improving, the negative air pickup system around the double-end tenoners. While these changes are being implemented, all employees in this area should be protected against those upset conditions which typically arise i^iiH nq system iuodifications. ' -- a 2) The peocant behavior of several employees working in the mineral core areas of the Coro Mill; namely, the dOuble end tenoner and electronic arehs, indicates the need now for a strong reminder (masks required) in the north aisle.

Slocncs & Goa bv Weyerhaeuser m .R &fica -7- 3} Alleviate the cynicism which is boiling over the facetious magical boundary between support posts along the north aisle preventing airborne transport of asbestos fibers from the double-end tenoners across the north aisle to the work stations of the two rail sawyers. I. As in the case of the drinking fountain cover in the Mineral Core Plant, the drinking fountain cover in the Core Hill should be extended with a foam rubber strip around the periphery of the lid to restrict admission of asbestos fibers to the noz2le area between uses. Sanitization should also be conducted on a regular basis on the top of the drinking fountain and the underside of the lid to allay employee anxiety regarding unsanitary conditions. The lid on this drinking fountain should not be propped open, as observed in the Mineral Core Plant. J. A ventilation deficiency was noted on the dual saw CM-10 in a rather qualitative manner. When the switch activating a valve to close a gate is flipped from "wood* to "mineral," about one-half the pull in the main duct leading from the saw to the main system is in evidence vis-a-vis that obtained for wood. Investigation of this problem revealed a potential bottleneck at a manual gate approximately 2-31 from where the duct from CM-10 enters the main negative air system line- Opening the manual gate at this position more completely may resolve this dis crepancy. K. vacuum clean-up drop legs have now been installed around the two double-end tenoners (FD-9 fc FD-10) operating on mineral core full-time and the Crt-20 double-end tenoner, which handles mineral core block tongue and grooving only occasionally. These additions are excellent examples of a continuing asbestos control program which ultimately will bring the Marshfield complex into compliance with the 1976 OSUA asbestos standard. Volume and correspondingly, velocity, Of air entering these drop legs was found to be somewhat reduced when mineral core is being handled on the double-end tenoners and the abrasive planer simultaneously versus when the double-end tenoners only o are connected to the system. If some conveniently detachable handle could be used in conjunction with the present drop legs, o it would greatly facilitate clean-up, especially in large open areas. Such a modification is recommended to make the employees clean-up tasks easier, thereby encouraging continued 5 employee cooperation. Z h.Oj J.

M. Commendation is certainly in order for those involved in 016 saw travGl trac* on through the use of lead With the center groove now leaded in ana the rip-saw during a typical cut producing no visible dust, it is doubtful that .Sr this machine center will become a significant health problem. O c Inspection of tho washer and dryer for Core Hill en^loyees' uniforms showed that the filter in the washing machine was O' P' flogged and most certainly not functioning as it was n tho filter " * appropriate to maximize efficiency of fiber removal from the contaminated Uli1.VOOI3 * 0* A recent problem with an ostensibly abrasion-type dermatitis among many of the Core Hill employees required to wear uniforms precipitated a study of present work practice and uniform cleaning procedures. As near as is possible to tell from story re-creation and direct investigation, the trichloro- G isocyanuric acid used in Davies Hi-Brite bleach is not being n adequately removed from the uniforms and therefore may be causing a sensitization dermatitis. Restricting the size of :r". l0f ,, ^ 016 washing machine and/or washing uniforms without bleach may be the best ways to eliminate the problem. P ` Thc *?ew innovation which has been applied to the lite opening routers in the Detail Department very likely will brinq these machine centers to within the 1976 OSHA asbestos standard. S ^ i ! ! Bin9 efforts on mineral du3t control at the drilling asbestof TM at " 1? K ^ et "rtiai*9 stations should eliminate asbestos concerns m this department within the year.
