This program should ineluda pre-employment, raassignaant, and periodic audlonatrle examinations and issuance of ear protective devices to Individuals working in noise haaardous areas. B. The area in Building 433, adjacent to the Rstans dicer and granulator, must be regarded as a noise haaardous area, and personnel working there should be equipped vith ear protective devices. C. expedite an engineering program for noise reduction at various sites of noise origin. Special attention and consideration should be given to the ,*nolseM eepect of prospective nav equipment. D. No atmospheric problem of excessive MDI concentration currently exists la the Bataan manufacturing area. Housekeeping in this area is poor, however, aid sloppiness In this respect may eventually lead to serious industrial hygiene problems where any of the dlIsocy anates are handled. K. The entire warehouse area in Building 433 may at times present both noise and dust hasards. The Bstaae dicer aad granulator ere located here and both are sources of excessive noise. Ail personnel In the warehouse should be included under the hearing conservation program aad attention should he directed to reducing noise originating from this equipment. F. The dicer operator on the Sstane line and othar personnel In the immediate area should be supplied with U.S. Bureau of Mines respirators approved for silica dust. Initiate action immediately for installation of local exhaust ventila tion to confine and remove duet from this operation. II. Results and Dlscuasloo A. Noise Table I presents results of noise measurements performed at eight different locations. 1. Measurements at Location No. 1 (CM line at bagger stations) indicate haaardous noise no longer exists In this area. Results of the current survey will be checked on a future visit, end. If verified, personal ear protective devices will no longer be required in the area. 2B103001 * hwrlouil;, boIm aMwmnti had been made at this location (Im report of 7-H-W) after heavy curtains had bean leatallod to close the 6'a6' opening la the north end of the either enclosure. Although these curtains aided In reducing noise at the bagger stations* they did not succeed In bringing the critical octave band average below 85 decibels. The curtains had beas replaced by a rigid* transparent* plastic panel at the tine the current measurements uere made and this device appears adequate for llnlasting hesardous noise exposure at the bagger stations. 2. Noise at the bagger station on the No. 2 Banbury lino rant ins at a hesardous level. However* a recant attanpt to reduce the noise level has bean partially successful, A curtain of flexible vinyl strips (each atrip approximately 4" vide) has bean suspended la the region between the cubor and bagger station. Noise neasureaents at this bagger statlem on March 29* 1946 (See report datod April 22* 1966) showed a 90 decibel average of the 300*600, 600*1200, and 1200*2400 decibel octave bends. Current neasureaents, with the flexible vinyl curtain in position, show an 88 decibel average over these octave bands. Additional Measure ments will be necessary to determine If this 2 decibel reduction Is directly attributable to the presence of the curtain. The noise level at the bagger station remains too high, however, even with the curtain la place, but if the 2 decibel reduction Is shown to be real, perhaps further refinement and engineering of this type of barrier will provide satisfactory nolaa control. 2acently, at the suggestion of Mr. A. Vlttome, two nenbars of the Corporate Division's Haw Product Planning Group were asked to consider BfO'e Deadbeat material for uae in this noise problem. Mr. Don Smith and Mr. John Peterson of the New Products Group, will visit the Avon Uka Plant to obtain first-hand Information on this project. Suggestions sad recommendations will be submitted to the Plant. 3. Nolee measurements at Locations 4, 5, and 6 ware obtained for a matter of interest and record. Noise In the Drier Building (No. 452) appears to be adequately controlled. On the first floor, between the No. L and No. 2 drier eoess, an average of 83 decibels exists over the critical octave bands. This is an acceptable level. Inside the grinder rooms extremely hesardous noise levels exist and continuing precautions should be exercised to prevent personnel exposure to this noise without proper ear protective equipment. Bar muffs are now worn by personnel entering these roomst time in the rooms should be held to an absolute minimum. Doors to the roams should be nslateload In good operating conditions to assure complete and positive closure. 4. Hazardous noise areas exist in Building 433 (Batane).

One af these areas la Building 452, tha Briar Building, and the other Is Building 433, specifically, tha warehouse area housing tha Katana line where Ceb-Q-Bii and Superfloaa are handled. The duet condition existing In Building 452, arising fron the drying of paste resin, cannot reliably be evaluated at tha present tlat because of a lack of background Information relating PVC dust concentrations to pulmonary offsets. It is evident from observation that a continual air* borne dusty condition oxiats within the Drier Building and recent measurements place the concentration of thla duet at 3 milligrams per cubic aster. This la probably a conservative value since one of the driers was Inoperative during the tine these samples were obtained, end visually, the atmospheric duet condition was'estimated to be minimal. A dust concentration of 15 nllllgrama par cubic meter Is generally accepted as a tolerable limit for Inert or nuisance particulates and this la considerably greater (5X) than the PVC dust concentrations recently BFG46410 5 measured la Building 452. It haa buna prttUMd, la tba past, that FVC duat may be regarded as aa inert or nuisance partleulate, but Uttla rallabla Investigation has boon performed to substaatlata this presumption. Hi-fil aad ftiparfloss are balag uaad la lneraaolag amounts in Building 433 aa a dusting (aad cosqpouadlng?) aatarial for Kstane. Oaa short run which was observed esn the Katana line la the warehouse area produced extremely dusty conditions. A single saaple for airborne dust taken near the operator's position on the platform near the dicer, resulted la a saaple with a duat concentration too high to count. A second saaple taken approximately 20* from the dicer chewed an airborne duat concentra tion of l nillloa particle# par eublc foot (nppcf). The recoasaanded allowable concentration for crystalline quarts (filOj) ta 2.3 nppcf. It Is likely that this concentration night be easily exceeded la the general atmosphere of Building 433 during a lengthy run employing the Sstane dicer. Duat concentration la the dicer operator area is highly excessive on even s short run and presents a hasardous situation. RMW/je 11/8/66 Kobert V. Modre11 26103005 BFG46411
