IO ROBINTECH INCOMOMT CD corporate orrice* (817) 332-7323 P.a BOX 2342 FORT'WORTH, TEXAS 76101 STATEMENT OF ARTHUR A, SMITH Vice President of Operations Robintech Incorporated Fort Worth, "Texas Prepared for Presentation at the Department of Labor Hearing on Vinyl Chloride; Occupational Exposure Standard June 25, 1974 - I am Arthur A. Smith, presently Vice President of Operations for Robintech Incorporated, headquartered in;Fort Worth, Texas. Robintech is a producer of polyvinyl chloride resin with; plant in Painesville, Ohio. A second plant is cinder construction at Freepbrt, Texas. f' Robintech is also a manufacturer of PVC pipe and fittings. We currently operate nine plants in eight states with the tenth plant under construction. We have two other plants on the drawing boards. I left the teaching profession and began itiy industrial work career in the early 1950s, when I was employed .by a PVC Resin Producer (Diamond Alkali), as a chemist in its quality control laboratory. This work assignment required daily analysis of vinyl chloride monomer and polyvinyl chloride resin. Due to the state of the art at that time, my activity required daily contact with liquefied vinyl chloride monomer. As our product line expanded, I began working on polymer develop ment in our polymerization pilot plant to develop and prove out recipes for new and/or improved resins. At this point in time, I began doing some Technical Service work OLI 938 *\ RDBINTECH ihceroR*tto CO**RATE OFFICES Statement of Arthur A. Smith Occupational Exposure Standard Page 2 * with customers in their processing or converting plants. In the late 1950s, I changed assignments and began working solely in Technical Service and Sales, calling on all types of processors and convertors using polyvinyl chloride resin. 4 This involved working with customers on their equipment in search of solutions to specific problems in extrusion, calendering, and molding. Since the early 1960s, I have been in the management of either sales or manufacturing (processing) of polyvinyl chloride resin. In my present position, when we received word about the alleged tie between vinyl chloride monomer and angiosarcoma of the liver this year, we began monitoring our products for residual VCM, monitoring our PVC plant, and monitoring^>ur pipe and fittings plants. As the potential for processing plant involvement became a question, I became associated with the SPI committee and worked with the task force assigned to study the fabricator situation. It would first be well to recognize there are hundreds of processing plants with multi-product lines within the same facility. Many processing plants utilize only pelletizing compounds. Some use both resin and pelletized compound, while others use only specialized OLI 939 \ RDBINTECH iNCOBPOMATCO corporate offices Statement of Arthur A. Smith Occupational Exposure Standard Page 3 resins. The main difference between pelletized compound and resin is that the pelletized compound has additives incorporated and has been subjected to an extensive heat history. There is still another category of processor who utilizes a powder blend compound which has also been subjected to heat history. There are combinations of types of processing plants such as molding, calendering, extrusions, and coatings. There are also numerous combinations within these types of processes. I have been working on the task force investigating and collecting data from the processors plants. We have collected data from numerous sources, even some from Europe. Since no two plants are alike, we set out to have all our plants monitored and results obtained on the same methodology with same instruments and same technicians. In addition to this, we have requested our insurance carrier to make the same survey with their Industrial Hygienist and both sets of this data are attached. This data teaches us that our range is from no detectable level on the low side to tfisS ppm; that level being present only directly above the intensive mixer. Personnel carbon tube sample for the same ar a shows 15.4 ppm vinyl OLI 940 N RDBINTECH inco*oaat co COftfOftATE OFFICES Statement of Arthur A. Smith Occupational Exposure Standard Page 4 37-L, chloride. This high level of ppm can readily be eliminated by venting the mixer through safe work procedures. The mixing room areas range from zero ppm to a high of 20.5 ppm. In connection with this area of the plant operation, it is felt that if the area meets the current clean air portion of an existing standard - 1910.93, the employee will not be exposed to hazardous levels of vinyl chloride monomer. Based on all our findings, we join in the view that processing plants should be excluded from the coverage of the proposed standard, since it has been demonstrated that there is no significant exposure for employees in ar as other than in mixing operations, where readily attainable ventilation and work practice procedures will eliminate any possible danger. * AAS/if Arthur A.

PLASTIC PIPE PLANT HILLSBORO, TEXAS HAY 10, 1974 On May 10, 1974, an industrial hygiene survey was conducted at the above location to determine concentrations of vinyl chloride in the working atmosphere. Recent studies have implicated vinyl chloride as the possible cause of a rare form of liver cancer known as angiosarcoma. Present Federal standards limit permissible working air concentrations of vinyl chloride to a ceiling value of 50 parts per million. A new standard has been proposed, however, which would make any detectable level of vinyl chloride a violation (based on a method sensitive to 1 part per mi 1.1 ion). Battery-operated MSA Monitaire Pomps were used in conjunction with activated charcoal tubes to collect seven (7) air samples in the resin mixing and ex trusion areas. Subsequent analysis by gas chromatography yielded the fol lowing results' .

The use of a resin with large amounts of unreacted monomer v/ill obviously produce higher air concentrations of vinyl chloride. This data indicates the use of a high quality PVC resin. If this continues, VC air concentration should remain low. If there are any questions regarding this report, please contact me.
