PRESENT: MINUTES AMBIENT VINYL CHLORIDE STANDARDS COMMITTEE MEETING Cleveland Office February 20, 1974 E. W. Harrington H. R. Rex A. M. Fairlie John Gressler H. Waltemate L. B. Crider G. H. Metzger C. R. Flynn G. D. Schaaf f 1. To clear up any misunderstanding, the following units of measure are defined: A. The residual vinyl chloride in PVC resins is measured and reported in weight percent. B. The OVA and Bendix readings are measured and recorded in volume percent of vinyl chloride in air. The OSHA standards for gases in air for time weighted average and TLV are also expressed in volume percent in air. 2. The amount of residual vinyl chloride level in our finished products was re viewed with H. R. Rex from Sales. The data to date indicated a problem (above 1,000 parts per million) with solution resins and Geon 202. G. D. Schaaf will review with ths plants what can be done on a short-term basis to reduce this level. Marketing will prepare a position paper for review with the LMG. All resins must be reduced to the lowest residual vinyl chloride content possible, consistent with our current processing conditions. A list of resins for criti cal applications has been prepared by Marketing and is attached to these min utes . Manufacturing and Marketing will review what should be done with hi temp resin and compound which contains sizeable quantities of residual carbon tetrachloride. 3. Ventilation is proceeding on a design basis for 6, 12, and 20 interchanges at all plant locations. At the Henry plant it may be necessary to provide two ducts for air intake; one to the North and one to the South. This system then would be used with a damper depending upon the wind direction. 4. Herm Waltemate reviewed his discussions with the NIOSE representatives at the Pedricktown plant. He will prepare a set of revised guidelines as a result of 22852001 NOTE: Underlining denotes "Action Items" BFG22807 Ambient VC1 Standards Committee 2 this discussion. In general they were convinced that we could use a throw away suit for dry poly entry. In case of a entry into a wet poly, we would have to use an impervious suit or one similar to rain gear. A wet poly is defined as a vessel in which the operator would be likely to come in contact with slurry or water. The NIOSH representatives were quite impressed with the housekeeping at the Pedricktovn plant and they felt the operators were not exposed to as much dust as the operators are in the Louisville plant. Mr. Harrington said that as a result of a meeting with management on the 16th, all plants have been requested to implement the NIOSH standards, and to identi fy what pros lens are created as a result of this-order. A routine report will be issued by each plant snceing their compliance with the NIOSH standards in t'neir progress toward that goal. 5. It was recommended that Ed Katzenmeyer pet together with NIOSH representatives in Cincinnati to obtain their guidelines on measurement of dust. It appears they have some information that would be useful in our plants. 6. L. B. Crider summarized the results of the tests with the cartridges from our respirators supplied by Welsch. The preliminary information indicates that vinyl chloride concentrations as high as 100 parts per million can be protec ted against for one hour in normal breathing operations (30 liters per minute). Work will now be done to identify the breakthrough point at 500 parts per million. It appears that we can use the respirator cartridces for one shift before discarding under present conditions. More data will be supplied later. 7. The background level of our OVA's range from 5-7 parts per million. Currently, we cannot subtract this from our OVA reading since we do not know what is the cause of the background. It is possible the background is caused by measuring residual carbon in the air of the normal environment or the background can be caused by some problems in the instrument itself. L. B. Crider will work on this problem to define the causes of the background level. The problem with the use of the Bendix is not severe, since we have a completely enclosed sam pling system and always have a constant source of air for calibration and no changing of cylinders is required such as with the OVA which could contribute to a variation in background levels. 8. Currently there are five sampling systems on order from Bendix to be used with the total carbon analyzers. It was agreed to purchase six more sampling systems so that the n|ants would have them in tine to use with their Bendix instrument. 9. Ed DeCapita has been sent to Louisville to monitor the concentration of vinyli- dene chloride in Building 15 on an interim basis. He will set up a plan where f: by the gas in the building is sampled and taken to the laboratory for analysis in the chromatograph. Next week we will then set up an infrared unit in the building to monitor for vinylidene chloride on a continuous basis. 01 N to BFG22808 rT Ambient VCl Standards Committee -3- 10. Mr. Harrington requested that OVA readings be taken in the Paste Drier Building since there is quite a bit of dust in that area. This will start at Louisville inane diatelv. 11. A. K. Fairlie presented the data requirements for the mini computer. A letter formulating these requirements will be sent out to all plants for their review. Mark Forsythe and Bob Carroll will review the requirements and recommend the type of computer system required. We want to provide a system that can store data so we can get a monthly report which can then be saved for at least twenty years to meet OSiiA requirements. A sample data sheet is attached to this report. GDS/ds Atts. 2/25/74 CC: Attendees E. B. Katzenmeyer B. M. G. Zwicker W. J. Wilcox E. G. Schwaegerle A. Vittone R. D. Scott J. L. Nelson R. N.
