Wilkins General The OSHA regulations are to go into effect April 1, 1975, assuming no action results from an SPI appeal to the Supreme Court. The table below from the December, 1974 issued of "Plastics Technology" suimnarizes the requirements of the standards: Table 1--EMPLOYER REQUIREMENT? Exposure Level, ppm <0.5 >0.5< 1.0 >1.0 Monitoring Program Medical Surveillance Medical Records Regulated Areas Roster of Authorized Persons Entering Regulated Areas Respirators Warning labels on Storage Containers Training None No No No No No Yes Ye* Quarterly Yes Yes No No No Yes Ye* Monthly Yes Yes Ye* Yes Ye Yes Ye* Data supplied by Diamond Shamrock Chemical Corp. GC 000747 Plastics Division Team - Meeting Notes Page 2 February 21, 1975 /t Plastics Division Fabrication Plants In the case of the bottle and film plants, it appears that all plants will be below the 0.5 ppm exposure level, thus requiring only a training program and warning labels on scrap containers, assuming it will be reprocessed. Columbia Pine Plant Data from recent Columbia sampling showed 0,48 ppm and 0.63 ppm exposure levels. Thus, in addition to the training program and labels, medical surveillance and records may be required for the blender operator. Additional sampling at Columbia is planned to determine the effects of repairs to the fan system and revisions to hopper car unloading procedure. It might be noted that resin during the sampling period contained 840-980 ppm VC1. Mr. Wilkins noted that most of this resin should be used by April 1st, thus reducing the exposure potential. Tiptonville Compounding Plant Personnel sampling, stationary sampling, and Century surveys were conducted during run no. 65T-2, producing 7042 wh 40 compound from SM-160 resin. The resin contained 1670-4400 ppm VC1 and finished compound con tained 161 to 286 ppm VC1. The Century survey indicated numerous locations with 1-10 ppm VCl in the atmosphere. Locations showing around 5 ppm VC1 where the operator was likely exposed were the additive hopper filling station and the boxing station. The potential exposure at the additive hoppers was due to the resin scale vent. A vent hood is being designed for correction. Based on the results of the Century survey, it is unlikely that the no action level can be met when processing non-steam stripped SM-160, Personnel were monitored during this period, but data are not yet available. Plans are to provide steam stripping capability for this resin at Baton Rouge. Comnercial scale steam stripping tests on SM-160 are underway. Unofficial results from previous Tiptonville personnel monitoring on a SM-250 based compound showed less than 0.1 ppm exposure on all 24 samples. Sandston Truck Unloading Ethyl traffic has indicated to the Sandston, Virginia film plant manager that a "regulated" area is required at the truck dock unloading pelletized film compound. We don't believe this will be required and are gathering supporting data. Thus far, we have the following: (1) None of the personnel samples obtained at Sandston have ever shown an exposure of greater than 0.1 ppm; 2) A trailer truck half loaded with 7053 showed a maximum exposure potential of 2.0 ppm when initially opened after four days' storage. Sub sequent samples taken one and two days later showed < 0.5 ppm exposure potential. GGC G00748 Plastics Division Team - Meeting Notes Page 3 February 21, 1975 (3) Film compound normally has less than 5 ppm VCl residual; based on the trailer tests, we would expect a maximum exposure potential of less than the detectable quantity. Results from two stationary carbon tube samples from the truck and from one personnel sample during unloading are not yet available. Financing The indicated final cost for the Part I appropriation is $74,000, as shown in the attached cost report. This does not include revisions and improvements to the systems as discussed below. Equipment Operability A list of operating problems and potential solutions was previously distributed to team members for comments. Inputs from plant personnel were discussed and the general scope of revisions defined. The immediate proposed scope is outlined in the attached Appendix A. Action Items 1. Mr. W. C. Baker will prepare a letter to Corporate Medical detailing Plastic Division's desires for personnel monitoring beyond that required by regulations. 2. Dr. C. P. Loechelt will compile a training manual (based on the Baton Rouge plant manual) for use in the Plastics Division plants. 3. Process Design will prepare process specifications detailing equipment revisions to be made at each plant. Next Meeting March 21, 1975 17th floor Ethyl Tower, Conference Room 9:30 a.m. DMM:mfl * D.
