SUBJECT VCM personnel Monitoring - Actual Vs. Potential __________________In Mask Monitoring Last February each FVC plant vas asked to report on Its vork on monitoring Inside respirator masks. The purpose of this vork vas to obtain data to justify raising the Lower alarm level from 1 ppm to 2 ppm or more. This vould enable a man to spend more time out of the mask and still maintain a 1 ppm TtfA. The data has been reviewed and it vas decided that monitoring vork inside the mask should be continued only at Avon Lake GCP. Other plants are no longer requested to perform in mask monitoring. The Avon Lake latex plant has been operating successfully for the past few weeks with the lover level alarm set at 2 ppm. During this period 21 monitorings inside the mask averaged 0.21 ppm. All except one were less than 1 ppm. Other plants wishing to raise the lover level alarm above 1 ppm should submit a request with justification for review. Several plants have asked if the Bendix flasher method is equiva lent to the NIOSH carbon disulfide method. Paul Zakriski expects to publish a report around August 1 canparing the two methods for monitoring 1 ppm VCM over a 6 hr. period. JAKjcj Distribution C.L. Woods-B.W. Holdman J.L* Nelson A.W.

I feel that I am not qualified to comment on the computer requirements. The purchase of the gas chromatograph should not be justified on health grounds for the following reasons: 1. There is no loss of sample integrity or in the accuracy of results from shipping the sample tubes to Brecksville or holding the samples under refrigeration. Dr. Paul Zakriski, Brecksville Environmental Laboratory, can be contacted for confirmation. 2. Individual plants have been requested to develop their own capabilities to do routine environmental analysis. Routine environmental analyses are those required by law or high use volume chemicals and such analysis as directed by the Environ mental Health Department. The only routine sampling that ALGC is required to do at this time and needs the use of a gas chromatograph is the vinyl chloride monitoring. Instru mentation is presently available at ALGC for this purpose. Other exposures that ALGC has that are done on a gas chroma tograph are acrylonitrile, -vinylidene chloride and pyridine, none of which are required on a routine basis. The exposures to acrylonitrile and vinylidene chloride in the plant are infrequent. Sampling conducted in the past has shown that acrylonitrile exposures are ^1.0 ppm with some short term exposures of up to 6.5 ppm. This data would indicate that a routine AN monitoring program is not necessary at this time. VDC is used in approximately 2 charges/month. Pyridine has been monitored in the lab and shown to be less than 2.2 ppm, below the TLV of 5 ppm. Again, there is no legal requirement for routine sampling for either of these compounds, therefore routine sampling is not recommended. Non-routine sampling, that is, sampling to characterize a process or its change, or sampling to evaluate a potential exposure or a new control can and should be accomplished through the Brecksville Environmental Health Laboratory. /l/r-t * * * & 8`'G-49S6-D 2/77 LITHO USA NGC 15460 December 16, 1977 TO; T.

NUMBER C.A. AMOUNT $30,000 EXPLANATION OF PROPOSAL (Explain need of proposal and method of accomplishment. Do not Include cost data here.) At the present time we monitor plant personnel for exposure to vinyl chloride utilizing a gs chromatograph committed to this single analysis and an old Wang minicomputer for data re duction. It is necessary that we provide additional analytical equipment and a larger data handling system so that we may carry out other required analyses and expand our computer capabi1ities. Hie approval of this project will provide instrumentation which will allow us to carry out the analyses now required. In addition, it will provide an adequate data reduction system with room for future expansion. The net effect of this project is that our laboratory will have the capability to monitor plant personnel for exposure to many other chemicals plus the ability to measure residual nitrogen bearing compounds in our plant products. We will also have the computer capacity necessary to handle all of our gas chromatography calculations plus other time consuming management programs. All of these needs and advantages have been detailed in Exhibit "A" and the Scope Summary. The complete proposal calls for the purchase of a gas chromatograph equipped with flame ionization detectors, a nitrogen/phosphorus detector and an autosampler plus a small computer equipped with dual mini diskette drives.

ALGC - Professional Services FIELO POINT OR DEPT. S. BLOB. NO. ALGC - Safety Department Exhibit "A" Meed for Additional Laboratory Services date vdub letter DATE THIS LETTER 8-1-77 With the ever growing list of chemical standards I feel the ALGC laboratory must develop the analytical capability to perform the NIOSH approved carbon disulfide (CS^) extraction technique for airborne hydrocarbons. At the present time all non vinyl chloride (VC1) samples collected at ALGC which require gas chromatography analyses are shipped to .the Corporate Environmental Laboratory at Brecksville. The Brecksville lab requests two weeks notice before any sampling and requires a minimum of two additional weeks before reporting the data back to the submitting plant. While the lead time required can be scheduled, with some difficulty, I am particularly concerned about the accuracy of the data due to the length of time between sampling and actual analysis. Analyzing the samples in the ALGC lab will insure the integrity of the data. The carbon disulfide extraction method can be used immediately for vinylidene chloride, acrylonitrile and pyridine monitoring. Community monitoring samples for vinyl chloride and other pollutants may also be analyzed by this technique. By enploying this method we will be able to collect twenty-four (24) hour community samples as recommended by Ken Kaminski in his correspondence to M. D. Rider of 7-20-77. The carbon disulfide extraction method is also suitable as a back-up for the Bendix flasher technique. I feel that having the capability to perform the carbon disulfide extraction technique will greatly assist our OSHA and EPA compliance programs. Therefore, I am requesting that you take the steps necessary to acquire the required equipment and train the needed technicians. If I may be of any further assistance, please call. M. C.

It is intended firstly to provide additional -instrumentation in the gas chromatography lab which will meet two specific and unique applications. Secondly# it will provide appropriate data reduction equipment which will not only meet all of our gas chromatography needs but will allow us to carry out certain technical and management programs. The programs are designed to minimize expenditures, reduce the budget to the lowest possible level and reduce testing error thus improving departmental performance. The data reduction system chosen will be expandable to meet future needs. These two purposes are defined in more detail in th following paragraphs. The ALGC laboratory has been asked to provide two distinct chromatographic servicesThe first# as described in Exhibit "A"# is that we develop the analytical capability to perform the NIOSH approved carbon disulfide extraction technique for airborne hydrocarbons. We have been asked to do this in order to assist the plant in meeting OSHA and EPA compliance programs. The second# as requested by Latex Technical and La Sales# is that we develop the ability to measure residual nitrogen bearing compounds our Hycar product line. An example of this would be residual acrylamide and residual n-methylolacrylamide in 2600X120 sold to Johnson and Johnson for baby diaper liners. This determination requires a nitrogen/phosphorus detector. In order to determine ho best to meet these dual needs, we met with several suppliers of chromatographic equip aent. We found that the Varian 3700# equipped with dual flame ionization detectors# an autosampler and a nitrogen/phosphorus detector would allow us to meet both needs. This would immediately eliminate the need of purchasing two separate instruments. Th major advantages of the Varian 3700 over competitive equipment are as follows. The d injection ports on the Varian 3700 are far enough apart that when one is covered (tak up) by the autosampler the other may be readily used. We will use the other injectio port for our latex work with the nitrogen/phosphorus detector. This is a major probl with competitive equipment where the injection ports are too close together. The Var autosampler injection system uses a dynamic# controlled-pressure purge rather than th. traditional aspirating-type syringe'injection. This means the dangerous fumes of car] disulfide, which is used in the NIOSH extraction technique# are confined within the instrument at all times. It will not be necessary to vent the entire chromatograph at would be with competitive equipment in order to protect the operator (s) from exposure this hazardous chemical. The ALGC laboratory currently uses an old Wang microcomputer# which was salvaged from phased out production project# to handle all gas chromatography calculations. It does not have memory capacity to handle programs exceeding basic type calculations. In addition to this# it is becoming difficult and costly to maintain. For example, our last service call cost $648.83 and Wang will no longer guarantee the service. Both the Wang representative and our own computer group recommend that the unit be phased out of service in favor of a new microcomputer or minicomputer of appropriate design. Although a Wang replacement is specified in the "Detail Estimate"# our computer group may recommend an alternative system such as an Imsai or a Digital since these systems provide more RAM memory and more floppy disk capacity at equivalent cost. This would allow for greater use of the equipment at the present time plus more future expansion. NGC 15465 Scope Summary (cont'd) The replacement unit will be used to run several other technical and management programs in addition to all gas chromatography calculations. Examples of these applications are as follows. Expenditures will be minimized by using the computer to carry out, in-house, programs currently run on time shared computers and by com puterizing overtime records. Budgets and subsequent expenditures will be reduced to the lowest possible level by utilizing the computer to measure operator efficiencie determine training (work organization) needs, determine manpower needs and balance workloads between classifications. Testing errors will be reduced by utilizing the computer to calculate HBR (half blind replicate) data, determine training (procedural) needs, establish experimental designs and evaluate experimental data and calculate test errors. A small computer has many applications in a large lab such as that at ALGO. Personnel Monitoring Chromatograph ALGC Project No. 652 DGD 12-12-77 -4- ALGC Project No. 652
