OBJECTIVES, CONCLUSIONS AND SUMMARY 1. OBJECTIVE Demonstrate that the amount of residual vinyl chloride monomer (RVCM) in Geon PVC resins and compounds is so low at the time of shipment from the BFGCC manufacturing plants that employees engaged in the transportation, storage, pro cessing and use of these products will not be exposed to quantities of ambient vinyl chloride (AVCM) above the action level of 0.5 part per million (ppm) averaged over an 8-hour work day under normal, good work practices without special engineering controls. Under these conditions it should no longer be necessary to use the cancer-suspect label on PVC packages. 2. CONCLUSION The testing conducted and reported herein demonstrates that personnel engaged in the transportation, storage, and processing of BFGCC resins are not exposed to vinyl chloride above the action level when resin containing a low level of RVCM is shipped. Much of the testing done outside of BFGCC manufacturing areas during 1974 was conducted on resins having much higher levels of RVCM than the same resins contain today. The significant decrease in RVCM achieved to date and the additional improvement anticipated by year end when new equip ment is installed provided further assurance that safe exposure will not be exceeded. 3. SUMMARY During the past year, BFGCC has determined the amount of RVCM in its resins at every manufacturing plant. This was done several times per week until new analytical equip ment was installed at each location to permit analysis of every production lot. Concurrently, intensive efforts were undertaken to minimize the amount of residual vinyl chloride in the resins. These efforts included modification of the physical structure of the resin itself to foster release of VCM as well as improvements in manufacturing techniques and in stripping process technology. Effectiveness of the program is indicated by the con stantly decreasing levels of RVCM. Resins not responsive to these techniques have been discontinued. Analysis of ambient vinyl chloride (AVCM), after ship >0 ment from BFGCC plants, in the transportation, storage, and C,d customer processing areas has shown that personnel are not h* exposed above the action level under normal, good work prac tices.

ANALYTICAL METHODS The method used to determine ambient vinyl chloride (AVCM) in the atmosphere, BFGCC Procedure No. 1021-T, is described in the appendix as Exhibit I. During 1974, glass sample tubes were used in accordance with the method approved by NIOSH at the time. During 1975, carbon tubes were used. The pump is calibrated for each sample and is operating during static samplings. The sensitivity' of the AVCM analysis is 0.01 ppm. The method now used, starting January, 1975, to determine residual vinyl chloride (RVCM) in PVC resin is BFGCC Procedure No. 1005-T, described in the appendix as Exhibit II. The sensitivity of this analysis on resin is 0.02 ppm. In the last part of 1974, a manually operated version of this method was used (BFGCC Procedure No.999-T, Exhibit III). Prior to October, 1974, a solvent method, similar to NIOSH P&CAM #178, was used. The method used to determine RVCM in compounds (both powder and hot mixed cubical granule types) is BFGCC' Procedure No. 937-C, described in the appendix as Exhibit IV. The sensitivity of this analysis on compound is 1.0 ppm. How small a difference between samples the test can detect reproducibly. BFG37834 io a o -v is z Page 4 III. RVCM CONTENT AT THE TIME OF PACKAGING IN BFGCC PLANTS A. Resin Samples of each resin are taken at the time of packaging whether the container be bag, box, bulk railcar, or bulk truck. The analytical method used during most of 1974 was solvent extraction of the sample and subsequent determination of VCM content in a gas chroma tograph. Starting in October, 1974, Perkin Elmer "Head Space" units, which analyzed the gas directly in the gas chromatograph, were introduced (BFGCC Procedure No. 999-T). Beginning February 1, 1975, all five plants were so equipped, permitting increased frequency of testing so that results are reported on each lot of resin. The- attached graphs (Figures 1-4 inclusive) on Geon resin 102EP F-5, 103EP, 103EP F-76, and 92, starting with the average values for the fourth quarter of 1974, show these average values on a weekly basis in 1975 for each manufacturing location at which the particular resin is produced.' A condensed summary of the 1975 data on which the graphs are based is contained in Table I. This includes the number of analytical tests used to determine i:he average value, the average of these determinations, as well as the highest single value and the lowest single value. During the Iasi quarter of 1974, 1,044 analyses were made on about 135,000,000 pounds of resin. In the first half of 1975, 2,700 analyses were made on about 175,000,000 pounds of resin. These data show the effects of product and process tech nology improvements in reducing the RVCM content of resins during this period from 100 to 150 ppm in the last quarter of 1974 to about 20 ppm in June of 1975. B. Compound - RVCM The RVCM content of compounds, as well as the RVCM of the specific lot of resin used in their manufacture, is listed in Table II. All of these compounds, except 85721 and 83824, were made by hot mixing in Banbury type mixers and are supplied in the form of cubical granules. The 85721, a rigid compound, and 83824, a flexible compound, were made in powder form on a high intensity, internal mixer. Of those compounds (48) made from resin having 20 ppm or less RVCM, 95% contained less than 1.0 ppm RVCM. Of the 18 compounds made from resin having 20 ppm to 100 ppm RVCM, only two compounds were above 1.0 ppm RVCM. There were three compounds made from resin containing more than 100 ppm RVCM. All three contained more than 1.0 ppm RVCM. BFG37835 rn o n T ,T p y Page 5 C. Compound - AVCM As a responsible manufacture under existing regula tions a study was undertaken to determine the relationship between the level of RVCM in resin and the degree of ex posure to AVCM in compounding operations within our own plants. Thus, the entire study was made under close control. The study involved five manufacturing locations where both resin and compound are made. The compounding operations included: 1. Mill Mixing 2. Banbury Mixing 3. Continuous Mixer 4. Sheeting, Granulating and Packaging Operations connected with each of the above 5. High Intensity Powder Mixing, Cooling and Packaging Products made include flexible and rigid compounds in both powder and hot mixed granule form. After resin is manufactured, it is stored in bins and transferred in bulk to the compound lines. RVCM content of the resin is determined on a sample taken from the bin. Thus, the time lag between manufacture of resin and consumption in compound is relatively short compared to that in a customer's plant since resin must first be shipped to his location. Personal monitoring was conducted on each of the operators involved in the compound manufacturing process, viz. the men involved in weighing, charging the mixer, tending the strip mill and packaging. The data determined in March, April, May and June, IS75 are included in Table III and plotted in Figure 5. The data indicate that, with resin containing less than 25 ppm (95% confidence) or 15 ppm (99% confidence), personnel engaged in the manufacture of PVC compounds are not exposed above the action level in the work atmosphere. These results are con sistent with those obtained in the modeling study discussed later in this report (page and Exhibit VIII). K C-.' H c n:\fv: Page 6 IV. FIELD TESTS DURING TRANSPORTATION, STORAGE, AND PROCESSING A. Introduction During the latter part of 1974, personal monitoring was done to determine the exposure of AVCM to personnel during transportation, storage, and processing. During this period, BFGCC did not have the capability to analyze each lot of resin for RVCM, but the data available in the previous section are sufficient to show that the levels of RVCM in the resins produced at the time of most of this testing were a great deal higher than the amounts contained in the equivalent products today, i.e., values of up to 150 ppm have been reduced to about 20 ppm. Despite the higher levels of RVCM, almost all of the personal monitoring in dicated that personnel were not exposed above the action level. The reduction of RVCM to low levels and the commitment that resin will not be shipped or used in compound should-the RVCM exceed this level provides assurance that those engaged in the transportation, storage, and processing of these mater ials will not be exposed above the action level under normal, good work practices. Evidence to support this conclusion has been developed in more recent testing based on low RVCM resin and compound, and additional support is provided by the VCM diffusion model ing study. B. Transportation Personal monitoring was conducted on men engaged in load ing and unloading bulk trucks and truckloads of bags of PVC resins and compounds. Bulk loading is done by gravity from a storage tank and unloading by air conveying under vacuum or pressure. A truckload of bags is usually loaded or unloaded with forklift trucks in 30 to 45 minutes. In the case of bulk trucks, monitoring is done on the truck driver who may make the hose connections and operate the valves for loading and unloading. In bag or box shipments, monitoring is done on the driver of the forklift truck used to move the pallets. The presence of combustion products from some forklift trucks using propance as a fuel interferes with the analysis for VCM, giving high values part of which are caused by the combustion products. In most recent testing, two carbon tube samples are taken so that, if the first reading is high, a second analysis can be carried out to distinguish between combustion products of propane and VCM. BFG37837 Page 7 Table IV shows results obtained by personal monitoring during the last quarter of 1974. Per sonal monitoring of forklift truck operators in 1975, with compounds based on lower RVCM resins, is included in Table v. Outside of the resin manufacturer's plant, these operations are short time and sporadic in nature. All instances were below the action level. The effect of the reduction of RVCM in resin on the amount of AVCM which can accumulate within a closed trailer for three days is shown in Table VI. C. Storage Table VII summarizes the AVCM data obtained in 1974 in public warehouses which contain from 50,000 to 350,000 pounds of PVC resins and compounds. Though some values with high RVCM resin are marginally above the action level, more recent data with low RVCM resin show results below this level. Evidence of this is co: tained in Exhibit v listing results obtained from the BFGCC warehouse in Louisville, Kentucky. Special engineering controls are not used in thisbuilding for there is no forced ventilation. Monitoring results are all below the action level. The amount of PVC raw materials in this warehouse was approximately 10,000,000 pounds. Exhibits VI and VII represent AVCM data obtained in BFGCC distribution centers at Avon Lake, Ohio, and Pedricktown, New Jersey. Both of these buildings contain in excess of 15,000,000 pounds of PVC resins and compounds. Both make use of forced ventilation. All of the results are below the action level except one at Pedricktown where the resin stored contained 69 ppm RVCM and the ventilating fans were turned off. D. Processing In Customer Plants Within customer plants, resin containing low levels of RVCM does not result in exposure of personnel above the action level in the work space areas. Equipment in which VCM may be released in confined areas above the action level include internal, high intensity powder mixers, Banbury mixers, and the various types of processing equipment such as extrusion and molding machines, as well as calenders. Such equipment is ventilated. Personal monitoring of operators actually working in each of these areas in 1974, shown in Table VIII, has never indicated exposure above the action level even with ^ resin containing up to 150 ppm of RVCM. Table VIII lists the results of 77 anilyses of personal and static monitoring carried ` out in nine customer plants during 1974. BFG37838 TT Page 8 Reduction of RVCM to less than 20 ppm increases the margin on safety as shown in Table IX. This table shows the results of 75 analyses of personal and static monitoring carried out in 1975 at eleven different customer plants. Static samples were taken in storage or processing points where AVCM would be expected to accumulate. At the same time, personal monitoring was conducted on operators working in these specific areas. In all cases, including the two where static sampling indicated a concentration above the action level, actual exposure of workers as determined by personal monitoring was below the action level.

A PHYSICAL MODEL FOR THE DIFFUSION OF VINYL CHLORIDE MONOMER FROM PVC RESINS UNDER VARIOUS CONDITIONS OF STORAGE A model, based on large scale laboratory experimental data, has been developed to show the relationship between the amount of residual vinyl chloride monomer in PVC resins (RVCM) and the concentration of atmospheric vinyl monomer (AVCM) under various conditions of storage. The variables studied in the experimental work leading to the development of this model included temperature, time, ventilation rate, RVCM content of the resin, mass/volume ratio and resin type (varying in porosity). The results obtained from a statistically designed series of 24 experiments show the interactions of all the variables and permit (1) the effects of the variables to be established, and (2) the derivation of a model which permits the AVCM levels to be predicted for any combination of the variables. The developed model has been used to predict the AVCM level in BFG warehouses at Avon Lake, Louisville and Pedricktown. We have found excellent agreement between predicted and measured AVCM levels at these three locations and under a variety of stor age conditions. Additionally, the model has been used to show that under less than the most severe storage conditions, the .OSIIA action level will not be exceeded (500 ppb AVCM) when the RVCM content of the stored resin does not exceed 18 ppm. Even under the most extreme storage conditions the OSHA action level is not exceeded when the RVCM content of the resin is 8.5 ppm or less. The details of this study are shown in Exhibit VIII. in J ,T P 'y BFG31840 r- RESIDUAL V IN Y L CHLORIDE (VCM) CONTENT 1 0 5 BFG37841 * o w Q in > E-i o 33 f P Ot b' U O N4 ro rin CN --i 00 ID CN rH m 00 o\ in rH o i--1 . oo in c a< n1 r H" CN l o w Q N< . > Bo f--A 3 P 04 B O o in m m i--i iH H 1--1 o o O rH ro co ro m in in H CO ro ro ID CN ro H1 i--l CM CJ\ VD o\ CN rH CN VD VO O VO CT\ o ncn oo i--i CN < H* 1/ i--1 cn r- N' ckn r~~ oo uo CN N* >1 Eh fa m <d o H wD CO CO 3 H1 CO CQ 1 w fa ..--, *--< cr e' u P< en > 04 '0w4' H K Cl w o3 fa w 13 H CQ CO p g f--f M 3Hu Hsw o. a 3i fa W o 04 w CQ CO O EH B fa a o 04 ci w Q ro > Bo 33 Bo 33 C 01 0 3O 3 01 04 B O O o 00 o rH CN o o CN in CN ro 1--1 o ro CN CO r* m ro o\ o 00 o m in o 00 rH CO H r- ro in ID in i--i VO CTi H oo ro in *h ro i--1 iH 00 o ro ID i--1 iH CT\ cn VO c\ rH ro CN O l) rH 00 <n 00 rH cn ro o in i--i ro cn ro ro CN rH cn rH O CO N* ro H* O 1--1 00 rH VD VD CO rH <7* iH CN rH rH ID i--1 00 04 CN in CN o CO 00 ro in CN ro rH ro a o rrH ro Cn rH i--1 CN rH cn N1 ro O rH ro >H CN rH ro CN rH in in r- rH IQ rH i--i H* CO VD r- VD r- n* rH H H ro o in vd ro rH CN CN VO oo in <y\ in CN i--I in VO o ro ro in o rH CN O N* 00 --1 iH ro rH rH rH O os rH n4 r- wm cn cn 4J 4-> -P P Cl 3 3 fa H H -H in H 04 01 0 m a) 0 01 0 01 0 >1 B Cn 3 04 id G i O'! 3 3 Pi 3 Cn 3 3 04 id i Cn 3 3 04 fa <d fa3 -H *H m Vi r-i *H td Sh -h H rd H -rt H cd 3 a) 3 X -P Pi a> C X P 0* 01 C X p- 01 C X 4-1 M CN > -H <$ nS 01 K H rtf id w > -H ctJ :d P > -H id id CO CTv fWa 1 a Q IN O S 3*!
